Mitre Saw Blade Sizes Guide

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.

Choosing the Right Tooth Count

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

Tooth CountCut QualityBest For
24-40TFast, roughFraming, construction timber, rough crosscuts
48-60TGood all-roundGeneral woodworking, softwood, MDF
80-100TExtra-fine finishHardwood, 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.
