The best Bosch Professional mitre saws, compared.
Top pick: Bosch GCM305-216S Best value: Bosch GCM305-216S – Lowest price in the set at about £209.49, with a blade, clamp and dust bag named, despite only three reviews. Updated October 2026.
A Bosch Professional mitre saw on amazon.co.uk is a corded or 18 V crosscut saw for skirting, architrave and timber. You tell them apart by the crosscut at the angle you will actually use, by whether the head bevels both ways, and by whether a battery is in the box. The score is editorial, from the amazon.co.uk stars, the review base, how clearly capacity and bevel are stated, the named kit and the price . How to order capacity, bevel and power before price is in the [Bosch Professional mitre saw buying guide](/hub/power-saws/bosch-professional-mitre-saw/sub/bosch-professional-mitre-saw-buying-guide).

Question 1 of 2
Where will you cut?
The GCM305-216S at about £209.49 is the cheapest corded saw in this set, and the three UK reviews from August and September 2026 describe an LED cut line that needed no adjustment and a front bevel control. Reviewers also mention a solid base, a smooth slide, and a clean cut in a hardwood sample, with the clamp, extensions, and dust bag in the box. One of those three reviews is based on test pieces only, so the 5.0 score is a short record. The listing does not print a wattage or a crosscut. Bosch’s GB page for part 0601B61070 states 70 x 315 mm at 0 degrees and a 47 degree left and 2 degree right bevel, which the amazon bullets do not. The dust bag is still not enough for heavy indoor cutting, and one reviewer plans to bolt the saw down because of the weight. The amazon weight cell says 20.4 kg, while Bosch lists 15.3 kg, so the cell is not the Bosch figure. It is best value if you will read capacity on the Bosch page.
Pros
Cons
Best for: You want a corded Bosch with an LED line and a clamp, and you will read capacity on the Bosch page.
Less suitable: You need a long UK review record, or a head that bevels fully both ways.
Specifications
Common questions
Does the GCM305-216S listing include a blade?
Yes. The included list names the saw, a measuring ruler, a clamp, a dust bag, a blade and a wrench. The blade diameter is not printed on the listing. The model is the 216 mm class.
Is the bevel dual?
The listing says the bevel control is at the front. It does not say the head tilts both ways. Bosch’s GB page for part 0601B61070 states 47 degrees left and 2 degrees right.
What mains voltage is printed?
The listing does not print a voltage or a wattage. Corded Bosch pages for this set state 220–240 V. UK mains are 230 V with a BS 1363 plug. This title is not a 110 V site tool.
The GCM 80 SJ listing at about £315.81 shows 4.7 from 462 reviews, with a 240 V cell, 1,400 W, 13.5 kg, and a 270 mm horizontal capacity in the bullets. The first 50 reviews come from Germany, Sweden, France, Spain, Italy, Belgium, and the Netherlands, and none is marked United Kingdom. Those reviews call the angles precise, including 45 degrees, and one notes there is no laser. A reviewer says the slide needs space behind the saw, and another says the clamp cannot be used on the right because the motor hits it. The title says two blades, while the bullets list one 216 x 30 mm blade, an Allen key, and a box. No dust bag is named. You pay about £86 more than the GCM 800 SJ listing for the same compact class unless a second blade is actually in the carton on the day.
Pros
Cons
Best for: You want part 0.601.B19.001 and you have checked how many blades are in the carton.
Less suitable: You can buy the GCM 800 SJ for the same 270 mm class at a lower amazon.co.uk price.
Specifications
Common questions
How many blades does the listing include?
The title says two circular saw blades. The bullets list one 216 x 30 mm blade, an Allen key and a box. Check the carton on the day you buy.
What capacity is stated?
The bullets state a 270 mm horizontal cutting capacity and a weight of 13.5 kg. A cut height is not printed on this listing.
Is a dust bag included?
No dust bag is named in the title or the bullets.
Across 75 amazon.co.uk reviews at 4.7, the GCM 800 SJ at about £229.80 is the compact sliding saw with a stated 270 mm horizontal capacity and a 216 mm, 24-tooth blade in the title. Thirty-one UK reviews praise accurate 45 degree stops, a smooth slide, and a slow-start 1,400 W motor for softwood, skirting, architrave, and a hardwood floor. Reviewers call the listed 13.5 kg light for the class. Several also say there is no laser, the manual does not explain how to adjust the square, and at least one box had no dust bag. One reviewer measured about 87 degrees at the 90 degree stop. The voltage cell says 24 while the title says 240 V, and the part-number cell says GCM 800 SJ (230 V), so the title is the voltage to read. Trench cuts are awkward: the bullets do not include a depth stop, and one reviewer improvised an M5 nut. It is the top pick when you want a compact corded slider for second fix on a 13 A socket.
Pros
Cons
Best for: You want a compact corded slider for skirting and second fix on a 13 A socket.
Less suitable: You need a cut line, a dust bag in the box, or a dual bevel both ways.
Specifications
Common questions
Is this GCM 800 SJ cordless?
No. The title says 240 V and the power source is corded. A cell that says 24 volts conflicts with that title. The part-number cell says GCM 800 SJ (230 V). Read the title.
Does the box include a dust bag?
The title lists a hex key and one 216 mm blade. It does not list a dust bag. One UK review says the bag was missing.
What crosscut does the listing state?
The bullets state a 270 mm horizontal cutting capacity and a weight of 13.5 kg. Bosch’s GB page states 70 x 270 mm at 0 degrees and 70 x 190 mm at 45 degrees mitre.
The GCM 18V-216 D at about £453.00 is an 18 V BITURBO body-only saw. The item type says solo, and the scope lists a 216 mm 24-tooth blade, two supports, a dust bag, and a clamp, not a battery or a charger. The rating is 4.6 from 91 reviews, but only one of the first 50 is marked United Kingdom. That UK review calls it light, usable for small jobs, and strong enough for bigger ones. The bullets state dual bevel. Bosch’s page for this model is 47 degrees both ways. The title says 66 x 305 mm and a bullet says 70 x 305 mm, so both figures are on the listing and they do not agree. A 1,600 W cell sits on this cordless saw and is not a Bosch specification in the bullets. Without an 18 V pack you already own, the price does not switch the saw on. Bosch names an EXPERT 18 V pack of 8 Ah or 12 Ah for runtime, and that pack is not in this price.
Pros
Cons
Best for: You already own Bosch 18 V packs and want a dual-bevel saw away from a socket.
Less suitable: You have no packs yet, or you need one capacity figure that the title and the bullets share.
Specifications
Common questions
Is a battery included?
No. The item type says solo, and the scope line lists a blade, two supports, a dust bag and a clamp, not a battery or a charger. Bosch recommends an EXPERT 18 V pack, 8 Ah or 12 Ah, and that pack is not in the price.
What capacity is printed?
The title says 66 x 305 mm. A bullet says 70 x 305 mm. Both figures are on the listing, and they do not agree. Do not treat either cell as settled until you check the Bosch page for your order number.
Does it bevel both ways?
Yes. The bullets state a dual bevel function. Bosch’s page for the GCM 18V-216 D is 47 degrees both ways.
The GCM 18V-254 D at about £619.07 states a cut up to 90 x 305 mm, dual bevel, and a 254 mm 48-tooth wood blade, with two supports, a dust bag, and a clamp. It is body only. The rating is 4.3 from 46 reviews, and five of the captured reviews are marked United Kingdom. Those UK notes include clean cuts, a joiner who liked the mitre index and bevel lock on a first test after an eight-year-old 110 V saw, and supports described as light but usable for longer lengths. The same small UK set includes a poor dust path, a blade one buyer wanted to replace, and a trigger that lit the laser and did not start the blade. The surface cell says wood and metal, while the included blade is named Standard for Wood. Bosch names an EXPERT 18 V pack of 8 Ah or 12 Ah for runtime, and that pack is not in this price. The 254 mm D models state 90 x 215 mm at 45 degrees mitre.
Pros
Cons
Best for: You own large 18 V packs and need the 90 mm class away from a socket.
Less suitable: You need a saw that runs from the box, or you are uneasy about a trigger fault on day one.
Specifications
Common questions
Is a battery included?
No. The item type says solo, and the scope lists a 254 mm blade, two supports, a dust bag and a clamp. An EXPERT 18 V pack of 8 Ah or 12 Ah is Bosch’s runtime advice, and it is not in this price.
What cut size is stated?
The title and the bullets say it cuts up to 90 x 305 mm. The blade is 254 x 30 x 2.2 mm with 48 teeth. The 254 mm D models state 90 x 215 mm at 45 degrees mitre.
What did UK reviews report on arrival?
Five of the captured reviews are marked United Kingdom. One describes clean cuts. One describes a poor dust path. One says the trigger failed on first use, with the laser on and the blade not turning.
The GCM 305-254 D at about £627.87 is the large corded saw in this set, with a stated cut of 90 x 305 mm, a dual bevel, and a 254 mm 40-tooth blade, plus two supports, a dust bag, and a clamp. Bosch’s GB page states 1,500 W, dual bevel at 47 degrees both ways, and 90 x 215 mm at 45 degrees mitre. The headline rating is 4.3 from 6 reviews, with three written UK reviews. One buyer says it does the cuts they wanted and is straightforward to set up. Another describes the build as good and then found the bevel detent jammed on arrival, so the saw could not be set, with cosmetic damage to the packaging. A UK review also says the slide bars need extra bench depth behind the saw. The voltage cell says 24 V and the wattage cell says 250 W, and neither figure is a Bosch specification in the bullets. At the listed 19.8 kg it is a bench tool, not a saw you carry between rooms.
Pros
Cons
Best for: You cut stock in the 90 mm class on mains and you can give the rails room behind the bench.
Less suitable: You want a compact second-fix saw, or a listing whose voltage cell matches a UK plug.
Specifications
Common questions
What cut does the listing state?
The title and the bullets say it cuts up to 90 x 305 mm. The blade line is 254 x 30 x 2 mm with 40 teeth. Bosch states 90 x 215 mm at 45 degrees mitre for the 254 mm D models.
Does it bevel both ways?
Yes. The bullets state a dual bevel function. Bosch’s GB page is 47 degrees both ways.
Can the wattage cell be used?
No. The cell says 250 watts and the voltage cell says 24 volts. Neither figure is in the bullets. Bosch’s GB page for this saw states 1,500 W. Treat 24 V and 250 W as conflicts, not as a motor rating.
Six Bosch Professional mitre saws on amazon.co.uk were scored out of 100. There is no laboratory cut. Star rating is up to 40 points, the review base up to 20, spec clarity up to 20, the named kit up to 10, and price in this set up to 10. The highest score is the top pick, once. Best value is the GCM305-216S, once. A 5.0 from three reviews does not outrank a 4.7 from 75 reviews.
Star rating
40%Up to 40 points, from the amazon.co.uk stars on that ASIN. The headline number is the stored rating, not a measured cut.
Review base
20%Up to 20 points, from the review count, with a lower figure when almost none of the captured reviews is marked United Kingdom.
Spec clarity
20%Up to 20 points, for a capacity printed on the listing and a bevel that is either dual or clearly limited. A voltage cell that fights the title is a deduction.
Kit
10%Up to 10 points, for a blade, clamp, dust bag and supports that the listing actually names. A solo box with no battery does not score as a complete kit.
Price in this set
10%Up to 10 points, against the other five GBP prices on amazon.co.uk. Bosch GB shelf prices are not mixed into this column.
Buy the crosscut at the angle you will use, then the bevel, then corded or body-only, and only then the shelf price. These six amazon.co.uk listings are not one Bosch Professional mitre saw. Two are compact corded sliders, one is a newer corded 216 mm saw, one is a large corded 254 mm saw, and two are 18 V body-only saws. The score is editorial. It is not a laboratory cut.
A Bosch Professional mitre saw, in the six amazon.co.uk listings in this set, is a corded or 18 V crosscut saw for skirting, architrave and timber. Prices run from about £209.49 for the GCM305-216S to about £627.87 for the GCM 305-254 D. The GCM 800 SJ is about £229.80, the GCM 80 SJ about £315.81, the GCM 18V-216 D about £453.00 body only, and the GCM 18V-254 D about £619.07 body only.
A 216 mm blade is not a 270 mm or 315 mm crosscut, and a 254 mm blade is not the same thing as 90 x 305 mm. Read the height and the width at the mitre you will use. The GCM305-216S listing does not print that crosscut. Bosch does.
The GCM 18V-216 D and the GCM 18V-254 D are body only. The scope is a blade, supports, a dust bag and a clamp. Bosch names an EXPERT 18 V pack of 8 Ah or 12 Ah for runtime, and that pack is not in the amazon price.
A cell that says 24 V, 250 W or 1,600 W fights the title on more than one listing. The GCM 800 SJ title says 240 V. Bosch states 1,500 W for the GCM 305-254 D. Do not use those conflicting cells as the motor rating.
Start with the cut at the angle you will use. Bosch states 70 x 270 mm at 0 degrees and 70 x 190 mm at 45 degrees mitre for the GCM 800 SJ, and 70 x 315 mm and 70 x 215 mm for the GCM305-216S. The 254 mm D models state 90 x 305 mm at 0 degrees and 90 x 215 mm at 45 degrees mitre. The GCM 80 SJ listing states 270 mm horizontal and does not print a height. The GCM 18V-216 D title says 66 x 305 mm and a bullet says 70 x 305 mm. The GCM 800 SJ bevel is 45 degrees to the left only.
Corded pages state 220–240 V. UK mains are 230 V and plugs are BS 1363. None of these six titles is 110 V. Both cordless listings are solo. Bosch recommends an EXPERT 18 V pack and names 8 Ah or 12 Ah for runtime, and that pack is not in the price. A dust bag is not an M-class extractor. HSE expects M-class or H-class extraction, and FFP3 when indoor trigger time reaches about 15–30 minutes. Hardwood dust is limited to 3 mg/m³ and softwood to 5 mg/m³ as an eight-hour average.
Three typical situations, each with a recommendation from this comparison.
You are fitting skirting and architrave on a 13 A socket, and you can check the square. The GCM 800 SJ is the compact corded slider at about £229.80, with 70 x 270 mm at 0 degrees on the Bosch page and a bevel to the left only. It is the top pick here. UK reviews say there is no laser.
You already own Bosch 18 V packs and you want the saw away from a socket. The GCM 18V-216 D is body only at about £453.00, with dual bevel and a 216 mm blade in the box. No battery and no charger are included. The title says 66 x 305 mm and a bullet says 70 x 305 mm.
You cut stock in the 90 mm class, or you bevel crown both ways, and you can give the rails room behind the bench. The GCM 305-254 D is the corded 254 mm saw at about £627.87, with 90 x 305 mm stated and dual bevel. One UK delivery had a jammed bevel detent.
The top pick is the Bosch GCM 800 SJ at about £229.80. It has the highest score in this set, 78, from 4.7 and 75 amazon.co.uk reviews, with a stated 270 mm horizontal capacity and a 216 mm blade. Bosch states 70 x 270 mm at 0 degrees and a 45 degree bevel to the left only. There is no laser in the UK reviews, and the voltage cell says 24 against a 240 V title. Best value is the GCM305-216S at about £209.49. It is the lowest price here, with a blade, clamp and dust bag named on the listing, and only three reviews, one of them test pieces. The listing does not print the crosscut. Bosch states 70 x 315 mm at 0 degrees for that part number.
Bosch GCM305-216S
