Bosch Professional GCM 305-254 D review

The only saw here that states its capacity as a cross-section — 90 × 305 mm — which is the number you actually need.

The bottom line The capacity machine. Buy it for the 90 × 305 mm figure or buy something cheaper.

Hands-on testing pending. Nothing below is presented as our own measurement. Every figure is a manufacturer specification, read off the listing itself, and the judgements are ours — drawn from how the specification behaves in this class of machine and from what long-term owners consistently report. Where a figure is missing, we say so rather than fill it in.

What the specification says

254 mm blade, dual bevel, a stated maximum cut of 90 × 305 mm, one blade and two workpiece supports in the box.

The specification everyone else should copy

Mitre saw listings quote crosscut width and cut height as two independent numbers, and they are not independent — on a sliding saw the achievable width shrinks as the workpiece gets taller, because the blade is a circle. A saw that says “340 mm” and a saw that says “90 × 305 mm” may well cut the same board, but only one of them has told you.

Bosch states the cross-section here. It is the number to plan around, and it is the reason this saw is on the page despite costing more than any other.

Dual bevel and the supports

Dual bevel means the head tilts both ways, so a matching pair of angled ends can be cut without turning the board over and re-registering it. On crown moulding and long runs of skirting this is where accuracy is won.

The two workpiece supports are not a luxury. A 305 mm crosscut implies boards long enough to tip the saw, and supports sold as accessories cost real money.

The British price

€546 in Germany, €578 in Spain, €685 in Italy, €700 in France — and roughly €1 314 in Britain, on the same reference and EAN. That spread is far outside normal currency and duty variation, and it is worth checking before ordering.

Availability

One reference and one EAN on all six markets, though the American listing carried no current price when we checked.

What we like, and what we don't

Strengths

  • Publishes its capacity as height × width, which no other saw here does
  • 305 mm of crosscut at a full 90 mm of height
  • Dual bevel, so matching mitres do not require flipping the workpiece
  • Workpiece supports included rather than sold as an accessory

Compromises

  • The most expensive machine on this page
  • The British listing is priced at roughly €1 314 against €546 in Germany
  • Heavy — this is a saw that lives on a bench

Questions people actually ask

Why is a cross-section figure better than a crosscut width?

Because the two interact. A saw rated for 340 mm of width usually means 340 mm at its shallowest, with the width falling as the workpiece gets taller. Stating 90 × 305 mm tells you what you can cut in one pass without discovering the limit mid-cut, and it is the honest way to publish the number.

Is it worth double the DeWalt?

Only for the capacity. The DWS777 has the better cut line and costs half as much; if 216 mm of blade covers your work, it is the better buy. This saw exists for the cuts the smaller ones cannot make at all.
