Best Bosch Professional mitre saw

Updated: 21 October 2026

Best only means something once you name the job. There is no UK lab test of these six amazon.co.uk listings, so this page will not call any Bosch a test winner. The best Bosch Professional mitre saw for skirting on a 13 A socket is not the saw for someone who already owns 18 V packs, and neither is the saw for timber in the 90 mm class. Prices in the [Bosch Professional mitre saw comparison](/hub/power-saws/bosch-professional-mitre-saw) run from £209.49 to £627.87. Peter F. compared those listings and public UK guidance.

Best for a house of skirting on mains

For a garage socket and a run of skirting, the GCM 800 SJ at £229.80 (B00S9XNPGQ) is the compact corded pick. The bullets state 270 mm horizontal capacity, 13.5 kg and 1,400 W, with one 216 mm 24-tooth blade. It has 4.7 from 75 reviews, 31 marked United Kingdom. Bosch’s GB page states 70 x 190 mm at 45 degrees mitre. The amazon bullet does not print that width. The GCM305-216S at £209.49 is the LED alternative, with capacity only on Bosch’s page, 70 x 215 mm at 45 degrees. The buying guide stays neutral.

Best if you already own Bosch 18 V packs

The GCM 18V-216 D at £453.00 (B0BTZ3QKC2) is the cordless pick only when the packs are already yours. The item type says solo: a 216 mm blade, supports, a dust bag and a clamp, not a battery or a charger. The bullets state dual bevel. The title says 66 x 305 mm and a bullet says 70 x 305 mm. Bosch names an EXPERT 18 V pack of 8 Ah or 12 Ah, and this set has no pack price. If you still have to buy the packs, the GCM 800 SJ at £229.80 does not stop when a pack is flat. Packs sit on the cordless or corded page.

Best when the timber is in the 90 mm class

A 216 mm compact is the wrong class when the piece is about 90 mm deep. Bosch states 90 x 305 mm at 0 degrees and 90 x 215 mm at 45 degrees mitre for the 254 mm D models. The corded GCM 305-254 D is £627.87, 19.8 kg, dual bevel, with 4.3 from six reviews. One UK buyer found the bevel detent jammed. The voltage cell says 24 V and the wattage cell says 250 W. Bosch’s page lists 1,500 W. Return a jammed detent. The cordless GCM 18V-254 D at £619.07 is solo. Five UK reviews include a trigger that lit the laser and did not start the blade. Choose corded with a socket and rear room. Choose the body only when the packs exist.

What not to call best

A 5.0 from three reviews is three reviews. The GCM305-216S can be the right LED saw, and it is not the best-evidenced saw here. It is filed under band saws, which is the wrong category. Skip the GCM 80 SJ at £315.81 unless you want part 0.601.B19.001 and you have checked the carton. None of the first 50 reviews is marked United Kingdom. The title says two blades and the bullets say one. You pay about £86 more than the GCM 800 SJ for the same 270 mm class.

Common questions

Which Bosch is the one to buy for a house of skirting?
The GCM 800 SJ at £229.80, if you have a 13 A socket and the board fits Bosch’s 70 x 190 mm at 45 degrees mitre. UK reviews use it for skirting and architrave. Skip it if you need a laser or a full dual bevel. The GCM305-216S is the cheaper LED option, with capacity taken from Bosch’s page rather than the listing.
Is the dearest saw the best?
No. The GCM 305-254 D at £627.87 buys a stated 90 x 305 mm cut and dual bevel, with a thin review file that includes one jammed bevel detent. For ordinary skirting on mains, the £229.80 GCM 800 SJ is the stronger pick in this set.
Is a 5.0 score from three reviews meaningful?
It means three people, all marked United Kingdom, and one had only cut test pieces. They liked the LED line. It does not outweigh 4.7 from 75 reviews on the GCM 800 SJ, and it is not a lab result.
Which cordless saw if I already own 18 V packs?
The GCM 18V-216 D at £453.00 for intermittent work in the 216 mm class, with 66 mm in the title and 70 mm in a bullet left as a conflict. Step up to the GCM 18V-254 D at £619.07 only for the 90 mm cut. Treat a trigger that will not start the blade as a return.
When is the 254 mm saw worth about £620?
When the timber is in the 90 mm class and a 216 mm compact is too shallow. The corded GCM 305-254 D is £627.87 and needs rear room for the rails. The cordless GCM 18V-254 D is £619.07 before any pack. Ordinary skirting stood on the fence does not justify that money.
Should I skip the GCM 80 SJ listing?
Yes, unless the two-blade title is real in the carton and you specifically want part 0.601.B19.001. The bullets say one blade, there is no UK review in the first 50, and the GCM 800 SJ asks £229.80 for the same 270 mm class.
Can you call one of them a test winner?
No. Nothing here was lab-tested. The picks are conditional: mains and skirting, packs you already own, or a 90 mm cut. A different job moves the answer.
