The bottom line A good cordless saw sold under a listing that will not say what it cuts. Price it in Germany, not in Spain.
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
A BITURBO cordless mitre saw on the Bosch Professional 18 V system, part number
0601B51000, bevelling in both directions from an ergonomic clamping wheel, rated
by Bosch for wood, aluminium and PVC. Supplied with a 216 × 30 × 1.7 mm 24-tooth
Standard for Wood blade, two workpiece supports, a dust bag and a clamp.
Compatible with Bosch extractors, GTA work tables and the brand’s cordless mitre
saw blades. No battery, no charger.
Capacity is the specification, and it is usually the missing one
A mitre saw is bought for two numbers: how wide a board it cross-cuts at
90°, and how wide it still cuts at 45°. Blade diameter is a proxy for
neither. A sliding saw on a small blade will out-cut a fixed saw on a
large one, because the carriage and not the blade sets the width.
The third number is what the saw manages at full bevel, which is always
less. A listing that quotes one capacity is quoting its best one; a
listing that quotes none, as several saws in this lot do, is asking you to
buy a machine on its silhouette.
The batteries are part of the price
AMPShare is the reason to buy into this saw rather than a corded one at half the
money: the same packs run the rest of the Bosch Professional 18 V range and a
list of other brands in the alliance. If you already own them, this is a €430
saw. If you do not, add two high-capacity packs and a charger before you compare
it with anything.
The prices
€430 in Germany, €455 in Britain, €474 in France, €559 in Italy, €599 in Spain.
One reference and one barcode across six markets, and the Spanish price is close
to 40 per cent above the German one for an identical machine. The American
listing exists but carried no price when we checked.

Questions people actually ask
Is this the GCM 18V-216 without the D?
The listing reads GCM 18V-216 D under part number 0601B51000, and the D matters: this is the version that bevels in both directions. We name the saw the listing names.
What is a dual-bevel saw actually worth?
It saves turning the workpiece around when a cut mirrors the previous one, which is most of skirting and architrave work. On a fixed-bevel saw you flip the board, re-mark and re-set; on this one you tilt the head the other way. It is a time and error saving, not a capacity one.
Can it really cut aluminium?
Bosch lists wood, aluminium and PVC. Non-ferrous metal on a mitre saw needs the right blade, a slow steady feed and eye protection, because the chips come off hot and sideways. The supplied 24-tooth wood blade is not the blade for it.
