A mitre saw (chop saw) is a stationary power tool with a spinning blade on a hinged arm that is brought down into the workpiece. The workpiece lies still on the saw table and the blade comes to the wood. Ideal for cutting beams, boards and profiles to length — both at 90 degrees and at an angle (mitre).
Types of mitre saws
| Type | Capabilities |
|---|---|
| Basic mitre saw | Only downward cuts, mitre left/right |
| Compound mitre saw | Also bevel cuts (tilting the blade) |
| Sliding compound mitre saw | Blade slides forward — cuts wider boards |
