Mitre Blocks

About Mitre Blocks

A mitre block is an essential hand tool for achieving precise angled cuts in wood, skirting boards, architrave, and other trim materials. This simple yet effective device features pre-cut slots at common angles - typically 45° and 90° - that guide your saw blade for accurate, repeatable cuts without the need for measuring or marking. The mitre block holds the workpiece steady whilst the slots ensure your tenon saw or backsaw follows the exact cutting line required.

These hardwearing tools are particularly valued by carpenters, joiners, and decorators who need quick, accurate mitres when fitting trim work, picture frames, or small mouldings on site or in the workshop.

Choosing The Right Mitre Blocks

When selecting a mitre block from MyToolShed.co.uk, consider these key factors:

• Material construction - hardwood or plastic blocks offer different durability levels; hardwood provides longevity for regular professional use
• Slot angles available - most blocks include 45° and 90° slots; check you have the angles required for your typical projects
• Capacity - ensure the block's width and depth accommodate the material sizes you commonly work with
• Build quality - precisely machined slots are essential for accurate cuts; look for established brands like Faithfull
• Usage frequency - professionals requiring daily use should prioritise robust construction over budget options
• Portability - compact mitre blocks are ideal for site work where space is limited

Frequently Asked Questions

What's the difference between a mitre block and a mitre box?

A mitre block is a simple, open-topped block with angled slots, whilst a mitre box has three sides (including walls) that provide additional support and guidance for the saw blade. Mitre blocks are more compact and portable, making them ideal for site work and smaller projects.

Can I use any saw with a mitre block?

Mitre blocks work best with tenon saws or backsaws that have a rigid blade and fine teeth. The saw's back edge should fit comfortably within the guide slots. Avoid using flexible saws or those with coarse teeth, as these won't follow the slots accurately.

How do I maintain my mitre block?

Keep your mitre block clean and free from sawdust build-up in the slots. Store it in a dry location to prevent warping (especially important for wooden blocks). Periodically check that the slots haven't widened from repeated use, as this can affect cutting accuracy.
