The best log splitter drill bits, compared.
Top pick: Spetsbst 45 mm and 32 mm set Best value: Ejoyous 32 mm hex cone – Highest value part among the listings that are not the top pick: about £12.50, and two of 11 UK reviews say it splits. Updated October 2026.
A log splitter drill bit is a threaded steel cone that chucks into a drill and wedges a log apart along the grain. In the UK you buy one for small, dry kindling when you already own a high-torque drill. It is a poor plan for a winter of knotted rounds. You tell a suitable log splitter drill bit by checks that stay true when the models change. The cone diameter has to match the pieces you split. The shank has to match the chuck. Round, hex, square and SDS-style adapters are not the same fitting. A screwed shank can unscrew in reverse and leave the cone in the log. Read the listing's own exclusion. If it says the bit is not for wood that is too hard, too wet or knotty, believe that line. The drill needs a side handle and a low gear. A bullet that mentions a hammer drill is not a reason to switch on hammer mode. The first session is in the [how to use a log splitter drill bit](/hub/drilling-and-accessories/log-splitter-drill-bit/sub/log-splitter-drill-bit-how-to-use) guide.

Question 1 of 2
What are you splitting?
The Spetsbst set lists a 45 mm head and a 32 mm head with four changeable shafts, at £15.52 and a listed 940 g. The listing line is 5.0 from 2 reviews, and both reviews in the file are tagged Reviewed in Germany, so that score is not a UK sample. Shank shapes are not named. The technical block prints power source hand_powered, while the title and bullets describe a drill-cone set, so that label is a catalogue field rather than a tool you turn by hand. The package is given as 12.9 x 12.6 x 5.2 cm. A five-star line from two Germany-tagged reviews is not a reason to prefer this set over a UK-reviewed cone.
Pros
Cons
Best for: Only a buyer who already accepts that the two reviews are not British shoppers.
Less suitable: A UK decision about whether the cone splits, or a reader who needs the shank shapes named.
Specifications
Common questions
What cone sizes does the bullet list?
A 45 mm head, a 32 mm head and four changeable shafts. Shank shapes are not named. Weight is 940 g.
Are the two reviews from the UK?
Both reviews in the file are tagged Reviewed in Germany. The 5.0 from 2 is the listing line. It is not a UK review sample.
Why does the file say hand powered?
The technical block prints power source hand_powered. The title and bullets describe a drill-cone set. Treat hand_powered as the catalogue label, not as a hand tool you turn yourself.
The Holy Feather set is two cones, 32 mm and 42 mm, each stated 90 mm tall, plus four shanks, at £9.97 and a listed 840 g. The listing is 4.4 from 2 UK reviews, which is the only positive UK pair in this capture and is not a trial on its own. One review says larger pieces may take several goes. The other says they would only use it on softwood and would start on an existing crack. A UK review names hex 6 mm, hex 10 mm, SDS and SDS+, while the attribute table only says shank type Straight, and a 25 mm dimension field conflicts with the 90 mm height. The bullets name beech, oak, birch and pine and do not print a wet-wood line. On that thin sample it is the top pick here for smaller or softer pieces, and two reviews do not make it a proven splitter.
Pros
Cons
Best for: Smaller or softer pieces when you already own a drill with a side handle and will start on a crack.
Less suitable: Large hardwood, or a buyer who wants a UK sample bigger than two reviews.
Specifications
Common questions
What is in the set?
The bullets say a 32 mm cone and a 42 mm cone, each 90 mm high, plus four shanks. A UK review names hex 6 mm, hex 10 mm, SDS and SDS+. The 25 mm item-dimension field conflicts with the 90 mm height.
Which drills do the bullets name?
The title and bullets name a hammer drill, an impact drill and an SDS-type rotary hammer. The attribute table only says shank type Straight.
What do the two UK reviews limit it to?
Both reviews are positive. One says larger pieces may take several goes. The other says they would only use it on softwood and would start on an existing crack.
The Saipor set is a 32 mm cone and a 42 mm cone with square, round and hex shanks, at £16.99 and a listed 1.07 kg. Across 27 amazon.co.uk reviews it sits at 2.8. The bullet says to start from the edge and does not recommend knotty woods or large-diameter hardwoods, in the same text that names oak, hickory, walnut and sycamore. UK reviews describe jams, a shank thread that did not match, a hole burnt in seasoned wood, and one SDS drill with a twisted shaft and a broken chuck. The title says 8 pieces and the piece-count attribute says 2, so those fields disagree. The exclusion is the useful line on the page, and the reviews still describe a cone that jams.
Pros
Cons
Best for: A reader who will follow the printed exclusion and still expects the jams in those 27 reviews.
Less suitable: Knotty wood, large hardwood, or an SDS drill you cannot afford to damage.
Specifications
Common questions
How many pieces are listed?
The title says 8 pieces. The piece-count attribute says 2. The bullet says two cones, 32 mm and 42 mm, plus square, round and hex shanks. Those fields disagree.
What wood limit does the bullet print?
Start from the edge. Not recommended for knotty woods or large-diameter hardwoods. The same bullet also names oak, hickory, walnut and sycamore.
What do UK reviews add?
The listing is 2.8 from 27. UK text describes jams, a shank thread that did not match, a hole burnt in seasoned wood, and one SDS drill with a twisted shaft and a broken chuck.
The METERXITY set at £19.49 is three cones, 38 mm, 45 mm and 50 mm, with four handles and gloves, at a listed 1.64 kg and a cone height of 9.2 cm. Across 34 amazon.co.uk reviews it sits at 2.6. The installation bullet says the bit is not for wood that is too hard or too wet, and that you should start at the edges and hold the wood so it does not rotate. Handle sizes are printed: square 45 x 9 mm, round 46 x 10 mm, hex 45 x 8.5 mm and small hex 32 x 6 mm. UK sentences in the file say the cone sticks, that it needs more drill power, and that it failed on several logs. Gloves in the box are not a reason to wear a loose glove against the thread. Three diameters do not repair a cone those reviews say sticks.
Pros
Cons
Best for: Someone who wants three diameters and a printed wet-wood exclusion, and who will stop when the cone sticks.
Less suitable: Wood the listing calls too hard or too wet, or a winter of rounds.
Specifications
Common questions
What must the wood be, according to the listing?
The installation bullet says the bit is not suitable for wood that is too hard or too wet. Start at the edges, not the middle, and hold the wood so it does not rotate.
Which handles are sized in the bullet?
Square 45 x 9 mm, round 46 x 10 mm, hex 45 x 8.5 mm and small hex 32 x 6 mm. Cone height is given as 9.2 cm. Gloves are included.
What do the UK reviews say?
The listing is 2.6 from 34. The UK sentences in the file say the cone sticks, that it needs more drill power, and that it failed on several logs.
The Ejoyous listing is a single 32 mm hex-shank cone, stated length 140 mm, at £12.50 and a listed 290 g. Across 11 amazon.co.uk reviews it sits at 2.6. Two of those reviews say it splits logs, and one of them says the cone can slip in the chuck. Others say it does not split large hardwood, and that a mains drill and a battery drill were burnt out in the attempt. The piece count is 1, and the included-components field only says inc, so extra parts are not listed. It is the best value here only as the other UK-reviewed cone in this set where a review reports a split, at a price below the three-cone sets. The burnt-out drills stay in the same picture, so this is not a second top pick.
Pros
Cons
Best for: A single 32 mm hex cone when a review that reports a split matters more to you than a second diameter.
Less suitable: Large hardwood, or a drill you cannot afford to stall.
Specifications
Common questions
What is in the box?
The piece count is 1 and the weight is 290 g. The included-components field only says inc, so extra parts are not listed.
Do the UK reviews agree it splits logs?
Two reviews say it splits logs, and one of those says it can slip in the chuck. Others say it does not split large hardwood and that a mains drill and a battery drill were burnt out in the attempt.
Which shank does the listing state?
Hex shank. Cutting diameter is 32 mm.
Across 221 amazon.co.uk reviews, the FOROREH 42 mm carbon-steel cone at £8.99 mostly drills in and jams, and that is the largest UK sample in this set. The box is four pieces, with square, round and hex shanks, and the listed weight is 666 g. Reviewers say reverse can unscrew the shaft and leave the cone in the log. The bullets name oak, hickory and walnut and do not print a wet-wood exclusion, which sits badly against those failed splits. You are looking at the cheapest listing in this capture, and the review record is the thing the price buys. It is not the top pick.
Pros
Cons
Best for: A reader who wants the largest UK sample on a 42 mm cone and already expects it to stick.
Less suitable: Knotted rounds, or anyone who needs the shank to stay on when the drill is put into reverse.
Specifications
Common questions
Which shanks does this listing include?
The bullet names a square handle, a round handle and a hex shank with the 42 mm cone. The piece count is 4. No gloves are named.
What do the UK reviews say about it sticking?
The listing is 2.5 from 221 reviews. In the first 50 UK reviews the repeated point is that the cone drills in and jams. Some reviews say reverse unscrews the shaft and leaves the cone in the log.
Does the listing exclude hardwood?
The bullets name oak, hickory and walnut and do not print a wet-wood or knot exclusion. UK reviews still describe failed splits.
The Spacnana listing is one hex-shank cone at £9.81, with a cutting diameter of 32 mm, a stated length of 140 mm and a weight of 290 g. Across 13 amazon.co.uk reviews it sits at 2.5. Those reviews say the bit sticks, and that reverse unscrews the adaptor and leaves the cone in the wood. One reviewer drilled the surrounding wood away to get the cone out. A battery drill is described as stalling on the same job. The title says 32 mm shank while the attribute field says cutting diameter 32 mm, so the file never separates those two figures. The bullets list one bit and do not confirm a case or a second cone.
Pros
Cons
Best for: A 32 mm hex trial when your chuck already takes that shank and you will stop as soon as it sticks.
Less suitable: Anyone who wanted a second cone, a storage case, or a compact battery drill.
Specifications
Common questions
Is the 32 mm the cone or the shank?
The title says 32 mm shank. The attribute field is cutting diameter 32 mm. The bullet adds a hex shank and 140 mm total length. The file does not separate the two 32 mm figures any further.
What happens in reverse, according to UK reviews?
UK reviews say the bit sticks and that reverse unscrews the adaptor, leaving the cone in the wood. One reviewer drilled the wood away to get it out. A battery drill is described as stalling.
Does the box include a case or a second cone?
The bullets list one bit. They do not confirm a storage box or a second cone.
This METERXITY set is 32 mm, 45 mm and 50 mm, with four handles and no gloves named, at £19.69 and a listed 1.57 kg. Across 11 amazon.co.uk reviews it sits at 2.5. The same exclusion is printed as on the sibling set: not for wood that is too hard or too wet, start at the edges, and hold the wood so it does not rotate. Cone height is stated as 9.2 cm. Two UK reviews in the file are blunt. One says the cone cut into bone-dry wood and the drill spun out of the hand. The other says a cone snapped off within 30 seconds. It is the sibling of the 38/45/50 mm set with gloves, at a similar price, with a smaller and harsher sample.
Pros
Cons
Best for: A 32 mm head alongside 45 mm and 50 mm, if you accept an 11-review sample that includes a snap.
Less suitable: Bone-dry hardwood, or a buyer who wanted the gloves from the other METERXITY set.
Specifications
Common questions
How is this different from the other METERXITY set?
This ASIN is 32 mm, 45 mm and 50 mm, part mma240703ty000515jp, £19.69, and the package line does not name gloves. The other set is 38 mm, 45 mm and 50 mm with gloves.
What wood limit is printed?
Not suitable for wood that is too hard or too wet. Start at the edges and hold the wood so it does not rotate.
What do the UK reviews say?
Two UK reviews are in the file. One says the cone cut into bone-dry wood and the drill spun out of the hand. The other says a cone snapped off within 30 seconds.
The WEDAMOO 42 mm cone is stated 90 mm long, with round, hex and square shanks, at £9.97 and a listed 590 g. Across 91 amazon.co.uk reviews it sits at 2.4, the lowest star line in this set with a double-digit UK count. UK text describes the log spinning, the cone sticking, a stripped thread and a failed 6 inch oak log. One review reports a wrist injury with a battery drill. The bullets name oak, hickory and walnut and do not print a wet-wood exclusion. The file writes each shank as 1/2 and does not say whether that figure is inches. A best-sellers line of 1 in Log Splitter Accessories is a rank in the capture, not a quality test.
Pros
Cons
Best for: A reader who wants the 91-review record on a 42 mm cone before spending the same £9.97 as the two-cone set.
Less suitable: Oak rounds, a battery drill without a side handle, or anyone who needs the thread to hold.
Specifications
Common questions
Which shanks are listed?
The bullet says a 42 mm cone, 90 mm long, with a round shank, a hexagonal shank and a square shank, each written as 1/2. The file does not say whether 1/2 is inches.
What do UK reviews report?
The listing is 2.4 from 91 reviews. UK text in the file describes the log spinning, the cone sticking, a stripped thread, a failed 6 inch oak log, and one wrist injury with a battery drill.
Does the listing exclude wet wood?
The bullets name oak, hickory and walnut and do not print a wet-wood exclusion.
The Wxeadu listing is a 50 mm cone plus square, round, hex and mini-hex handles, five pieces at £13.99 and a listed 940 g. The capture has no Customer Reviews line, so there is no UK star count to set a split against a jam. The bullet claims high-carbon steel with a heat-treated titanium coating, and the finish attribute says Titanium, with no hardness number. It names oak, hickory and walnut and does not print an exclusion. The included-components line names only the drill bit, while the bullet says four handles. A 50 mm cone needs more torque than a 32 mm cone, and this file cannot say whether that torque is enough, because nobody in the capture has reviewed it.
Pros
Cons
Best for: A buyer who specifically wants a 50 mm cone and will treat the missing reviews as a reason to wait.
Less suitable: Anyone who needs a UK review before chucking a large cone into a drill.
Specifications
Common questions
What is in the set?
The bullet says one 50 mm bit and four handles: square, round, hexagonal and mini hex. The piece count is 5. The included-components line names only the drill bit.
Is there a UK review score?
The capture has no Customer Reviews line, so there is no UK star rating to quote.
What material does the bullet claim?
High-carbon steel with a heat-treated titanium coating. The finish attribute says Titanium. No hardness number is printed.
Ten log splitter drill bits on amazon.co.uk were scored from the listings in this comparison. The saved listings were not re-checked on 22 October 2026. There was no lab test. The score is 0–100 from four parts: stars, the UK review sample, whether UK text reports a split, and value. A sample tagged Germany does not count as a UK star line. The highest score is the top pick, once. Best value is the highest value part among the listings that are not the top pick, once.
Stars
30%UK amazon rating divided by 5, then times 30, rounded. No review line scores 0. A sample tagged Germany is not a UK star line, so those stars score 0.
UK sample

Fit
30%UK text that reports a split on small, dry wood scores higher. A cone that bores, a shank that unscrews in reverse, a spinning log, or a burnt-out drill scores low. A printed exclusion is a small credit. It does not replace a reported split.
Value
15%What the box contains against the price, after the failure reports. Two cones and a thin positive UK note score high. A large UK sample of jams scores low. No UK reviews scores low.
Start with the size of the wood, then the listing's exclusion, then the cone and the shank. A star rating comes after those checks. The notes below follow that order for these ten amazon.co.uk listings. The saved listings were not re-checked on 22 October 2026. None of the scores is a drilling test.
A log splitter drill bit is a threaded steel cone that chucks into a drill and wedges a log apart along the grain. UK buyers are mostly households making small, dry kindling. It is a trial if you already own a high-torque drill. It is a poor plan for a winter of knotted rounds. UK reviews on this kind of listing repeatedly send you back to an axe, a hammer wedge or a hydraulic splitter.
Listings that print a method say start at the edge, or on an existing crack, and hold the wood so it does not rotate. Starting in the middle is where UK reviews describe a cone that bores and jams.
A bullet can name oak, hickory and walnut and, in the same text, say the bit is not for knotty wood or large hardwood, or not for wood that is too hard or too wet. Believe the exclusion. The species name is not a test.
On more than one listing, UK reviews say reverse unscrews the adapter and leaves the cone in the log. Stop when the cone is buried. A compact driver and hammer mode, because a bullet mentions a hammer drill, are the same class of mistake.
Job size comes first. These cones are a trial for small, dry kindling if you already own a high-torque drill. They are a poor plan for a winter of knotted rounds. UK reviews on this kind of listing repeatedly point back to an axe, a hammer wedge or a hydraulic splitter. Believe what the listing excludes. One three-cone set says the bit is not for wood that is too hard or too wet, and says to start at the edges and hold the wood so it does not rotate.
The shank has to match the chuck you own. Round, hex, square and SDS-style adapters are not the same fitting. One attribute table says straight while a UK review names hex 6 mm, hex 10 mm, SDS and SDS+. A one-piece shank and a screwed shank fail differently. On more than one listing, UK reviews say reverse unscrews the adapter and leaves the cone in the log. Read the sample, not the star alone. A large UK count outweighs 5.0 from two reviews tagged Germany.
Three typical situations, each with a recommendation from this comparison.
You have small, dry pieces, a drill with a side handle, and you will stop if the cone sticks. The Holy Feather set is two cones, 32 mm and 42 mm, at about £9.97. It is 4.4 from 2 UK reviews, and those reviews limit it to smaller or softer pieces. Two reviews are not a trial.
You want a single 32 mm hex cone, and a UK review that says it splits matters more than a second diameter. The Ejoyous cone is about £12.50, at 2.6 from 11 reviews. Two of those reviews say it splits. The same file includes burnt-out drills on large hardwood.
You want the listing to say what wood is out of scope. The gloved METERXITY set, 38 mm, 45 mm and 50 mm, at about £19.49, says it is not for wood that is too hard or too wet, and to start at the edges. It is 2.6 from 34 reviews, and that UK text still says the cone sticks. Large or knotted rounds belong with an axe or a hydraulic splitter.
Holy Feather scores 61, the highest in this set, so it is the top pick: 4.4 from 2 UK reviews, about £9.97, with 32 mm and 42 mm cones, and those reviews limit it to smaller or softer pieces. Ejoyous has the highest value part among the rest, so it is the best value at about £12.50. Two of 11 UK reviews say it splits, and the same reviews include burnt-out drills on large hardwood. The gloved three-cone set ties Ejoyous on 44 and loses on the value part, 7 to 8. A 5.0 from two reviews tagged Germany, and a listing with no review line, sit at the bottom. This is not a lab test.
Ejoyous 32 mm hex cone
Highest value part among the listings that are not the top pick: about £12.50, and two of 11 UK reviews say it splits.
