Log splitter drill bit buying guide

Updated: 23 October 2026

You already own a drill, and small dry offcuts are waiting by the stove. A log splitter drill bit looks like the cheap way to make kindling, while titles in this capture name oak. The UK reviews mostly describe a cone that bores in and sticks. Before you spend £8.99 to £19.69, check whether the wood is in scope, what the listing excludes, which diameter you need, and whether the shank fits your chuck and stays on in reverse. The ten rows are on the [log splitter drill bit comparison](/hub/drilling-and-accessories/log-splitter-drill-bit). Prices are the saved listings from 22 October 2026.

Is a log splitter drill bit the right job?

A log splitter drill bit is a threaded steel cone that chucks into a drill and wedges a piece apart along the grain. In this capture it is a trial for small, dry kindling when you already own a high-torque drill with a side handle and a low gear. It is a poor plan for a winter of knotted rounds. If the wood is large, wet or full of knots, skip the cone. An axe, a hammer wedge or a hydraulic splitter is the tool, set out on the log splitter drill bit vs axe page. A compact driver is the wrong drill even for a short offcut.

What the listing excludes

Believe the exclusion, not the word oak in the title. Both sets near £19.50 say the bit is not suitable for wood that is too hard or too wet, and tell you to start at the edges and hold the wood so it does not rotate. The 32 mm and 42 mm set at about £16.99 says start from the edge and does not recommend knotty woods or large-diameter hardwoods, in the same bullet that names oak, hickory, walnut and sycamore. Holy Feather names beech, oak, birch and pine with no wet-wood line. If the bullet excludes the wood in your basket, a larger diameter does not put it back in scope.

Diameter and how many cones

This capture runs from a single 32 mm cone to a 50 mm cone, and from one head to three. A larger cone needs more torque. More heads do not fix a cone that only bores. The 50 mm listing at about £13.99 has no review line, so that head is an untested claim here, not a step up. The £15.52 listing's 5.0 from 2 reviews is tagged Germany, so it is not a UK sample. UK text on the gloved set says it needs more drill power and failed on several logs.

Shank and whether it stays on

The shank has to match the chuck you already own, and it has to stay attached when the cone binds. A round shank belongs in a three-jaw chuck. A hex or square shank needs a chuck that grips the flats. An SDS or SDS+ adapter is not a three-jaw shank, and a review that names SDS is not a conformity mark. Holy Feather's table says shank type Straight. A UK review names hex 6 mm, hex 10 mm, SDS and SDS+. One box writes each shank as 1/2 and does not say whether that means inches. On FOROREH and on the 32 mm hex at about £9.81, UK reviews say reverse unscrews the shaft and leaves the cone in the wood.

What this capture costs

These ten top out at £19.49 to £19.69. betterout.co.uk listed a 32 mm and 42 mm set at £37.99. That is one shop price, not an average. The cheapest row carries the deepest record of a cone that sticks. If the wood is in scope, the first session is on the how to use a log splitter drill bit page. If the exclusion and the reviews both point away from your wood, do not buy one.

Common questions

What diameter should I buy for small, dry offcuts?
Start with the smaller head if the offcut is short and dry and your drill already has a side handle and a low gear. In this capture that is a 32 mm cone, or the 32 mm head in a two-cone set. A 42 mm cone is the other common size, and it asks more torque. A 45 mm or 50 mm head is a larger bite, not a better one, when the reviews already describe stalls and sticks.
Does a 50 mm cone need a more powerful drill than a 32 mm cone?
A larger cone needs more torque. That is the limit this capture supports. The 50 mm single cone, at about £13.99, has no review line, so nobody in the file has shown what drill turned it. The gloved set, which includes a 50 mm head, draws UK comments that it needs more drill power. This page will not quote a watt minimum from another site. If your only drill is a compact driver, neither diameter is the right purchase.
Will a hex, square or SDS-style shank fit my chuck?
Only if that chuck is made for that shank. A round shank is the three-jaw fit. Hex and square shanks need a grip that matches the flats. An SDS-style adapter belongs in an SDS chuck, not in a normal three-jaw chuck, and a review that names SDS is not a conformity mark. One table in this capture says Straight, while a UK review of the same set names several shanks.
Why do listings say oak if the same page excludes hard wood?
The title is the sales line. The bullet is the limit. One 32 mm and 42 mm set names oak, hickory, walnut and sycamore and, in that same bullet, does not recommend knotty wood or large-diameter hardwood. Both sets near £19.50 say the bit is not for wood that is too hard or too wet. A 42 mm cone names oak and does not print that exclusion, and 221 UK reviews still describe a cone that sticks. When the two lines disagree, follow the exclusion and the reviews.
When is the honest answer not to buy a cone?
Do not buy one for knotted rounds, wet wood, a winter of fuel, or a compact driver. Do not buy one if you need the shank to stay put in reverse and the listing you are looking at is the sort the 221-review cone and the 32 mm hex reviews describe, where reverse unscrews the adapter.
