An introduction to mitre saws: A mitre saw is a portable machine for making cross or, by rotating the tool's turntable, angle (known as mitre) cuts in wood. Mitre saws are used both in workshops & by onsite carpenters for window casings, architraving, door frames, picture frames etc. The wood is taken to the mitre saw rather than the machine being taken to the material as in a circular saw. The majority are mains powered but cordless versions do exist. Click here to see all our saws

To choose between mitre saws: The key criteria needed for choosing a mitre saw is the diameter of the blade to determine the width & depth of cut. Mitre saws with this 305mm diameter blade are the largest available. Click here to see all our mitre saws

To make sure you've got the right mitre saw - 305mm blade: Choosing your power source: 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
