Bosch Optiline Wood 216 × 30, 48T

Every figure below is a manufacturer specification read off the listing itself. The judgments are ours.

What the specification says

Ø 216 × 30 mm (8.50 × 1.18 in), 2.0 mm kerf, 48 teeth. Part number 2608640432.

Tooth count, in one paragraph

Fewer teeth cut faster and rougher; more teeth cut slower and cleaner. The reason is chip clearance: each tooth has to carry its chip out of the kerf, and a coarse blade has room to do it. A fine blade in a deep rip cut has nowhere to put the waste, so it heats up and burns.

Roughly: 24 teeth on a 250 mm (9.84 in) blade for ripping solid timber, 40 to 60 for general work, 80 for crosscutting and sheet goods where the finish shows.

Rake angle — the specification that matters on a chop saw

Rake is the angle the tooth leans forward. A positive rake pulls itself into the cut, which is what you want on a table saw where the work is fed against the blade. On a mitre saw, where the blade comes down onto fixed work, that same self-feeding is what makes the head snatch and climb.

Mitre saws want a negative rake. It is the single most important number on a chop saw blade, it costs nothing extra, and almost nobody checks it.

Bosch does not publish the rake angle for this blade, which is the one thing a mitre saw owner should check. Ask before ordering if the saw is a chop saw.
