Mitre Saw Blade Sizes Guide

Getting the right blade for your mitre saw comes down to two measurements: diameter and bore size. Mitre saws are designed for a specific blade diameter, and you cannot fit a larger blade. The bore is almost always 30mm on UK mitre saws. This guide covers every common mitre saw blade size, what it fits, and how to choose the right tooth count for your work.

Quick Answer

The three standard mitre saw blade sizes in the UK are 216mm (compact mitre saws), 254mm (mid-size sliding mitre saws), and 305mm (full-size sliding mitre saws). Almost all use a 30mm bore. Check the label on your mitre saw for the exact blade size — it must match exactly.

Blade Size	Saw Type	Max Crosscut Width (approx.)	Example Saws
216mm (8½”)	Compact mitre saws	~120mm at 90°	DeWalt DWS774, Makita LS0815FL, Bosch GCM 8 SJL
254mm (10″)	Mid-size sliding mitre saws	~300mm at 90°	DeWalt DWS778, Makita LS1019, Milwaukee M18 FMS254
305mm (12″)	Full-size sliding mitre saws	~340mm at 90°	DeWalt DWS780, Makita LS1219, Bosch GCM 12 GDL

Choosing the Right Tooth Count

Mitre saws are primarily used for crosscutting, so the tooth count affects the quality of the finish:

Tooth Count	Cut Quality	Best For
24-40T	Fast, rough	Framing, construction timber, rough crosscuts
48-60T	Good all-round	General woodworking, softwood, MDF
80-100T	Extra-fine finish	Hardwood, laminate, skirting boards, visible joints

Tip: For most DIY woodworking on a mitre saw, a 60T blade is the best all-rounder. If you’re cutting skirting boards, architrave, or anything where the cut edge will be visible, go for 80T or higher.
