Popular Irwin Squares & Bevels

The Irwin squares and bevels range at Tooled-Up includes several essential tool types for different measuring and marking applications:

Combination Squares represent the most versatile option, featuring an adjustable blade that slides through a multi-purpose head incorporating 90-degree and 45-degree reference faces. These tools enable checking right angles, marking parallel lines, gauging depths, and measuring from edges with a single compact instrument. Irwin's combination squares typically feature hardened stainless steel blades with etched graduations and cast aluminium heads with integrated spirit levels.

Try Squares offer the simplicity and reliability of a fixed right-angle tool, ideal for checking square assemblies and marking perpendicular lines. With their rigid one-piece or permanently fixed construction, try squares provide an absolute reference that doesn't require adjustment or calibration, making them indispensable for fine woodworking and precision metalwork.

Speed Squares combine a triangular body with multiple angle references, enabling rapid marking of common angles used in carpentry and roofing. These versatile tools serve as protractor, try square, saw guide, and rafter square in one compact package, making them particularly popular with construction carpenters and roofing professionals.

Sliding Bevels feature an adjustable blade that locks at any angle, allowing tradespeople to transfer complex angles from existing work or set pieces to marking operations. Essential for staircase construction, timber framing, and any work involving non-standard angles, these tools bridge the gap between fixed squares and protractors.

Safety and Compliance

Whilst squares and bevels are non-powered hand tools with minimal inherent safety risks, proper use and maintenance ensure accurate results and long service life. Always inspect blades and bodies for damage before use, as bent or worn edges compromise measurement accuracy. Ensure locking mechanisms on adjustable squares and sliding bevels engage fully before marking to prevent movement during use.

Irwin squares and bevels are manufactured to comply with relevant British and European standards for hand tools, ensuring appropriate materials, construction quality, and dimensional accuracy. When using these tools in conjunction with power tools or cutting equipment, always follow the safety guidelines for those machines and ensure measurements are double-checked before cutting expensive materials.

Store squares and bevels in toolboxes or wall-mounted holders that protect blades from impact and prevent warping. Avoid using measuring tools as pry bars, hammers, or scrapers, as such misuse can damage precision edges and compromise accuracy. Clean blades regularly to remove sawdust, metal filings, and corrosive substances, and apply a light oil coating to unpainted steel surfaces when storing tools in damp environments.

Frequently Asked Questions

What's the difference between a try square and a combination square?

A try square features a fixed blade permanently set at 90 degrees to the stock, providing an absolute right-angle reference for checking square assemblies and marking perpendicular lines. A combination square has an adjustable blade that slides through a multi-function head, enabling measurements, depth gauging, and marking at both 90 and 45 degrees. Try squares excel at dedicated squareness checking, whilst combination squares offer greater versatility for varied measuring tasks.

How do I know if my Irwin square is still accurate?

Test a square's accuracy by placing it against a known straight edge and marking a line. Flip the square over so the opposite side of the blade contacts the edge, then mark another line from the same starting point. If the two lines diverge, the square is out of true. For combination squares, check that the blade locks securely at each position and that the reference faces on the head remain flat and undamaged.

Can Irwin squares and bevels be used for metalworking as well as woodworking?

Yes, Irwin squares and bevels are equally suitable for metalworking and woodworking applications. The stainless steel blades resist corrosion from cutting fluids and metal filings, whilst the hardened edges withstand repeated contact with metal scribes. Many fabricators and welders rely on Irwin squares for accurate marking on steel, aluminium, and other metals, making them truly multi-trade tools.

What size combination square should I choose for general carpentry work?

A 300mm (12-inch) combination square represents the most versatile choice for general carpentry, providing sufficient blade length for marking wide boards whilst remaining compact enough for comfortable carrying. Smaller 150mm (6-inch) models suit fine woodworking and confined spaces, whilst larger 450mm (18-inch) versions benefit construction carpenters working with wide timber or sheet materials.

How should I maintain my Irwin squares and bevels to ensure long-term accuracy?

Protect precision edges from impact by storing tools in protective cases or designated tool roll compartments. Clean blades after each use to remove sawdust, metal particles, and moisture that could cause corrosion. Periodically check locking mechanisms on adjustable tools and tighten any loose fasteners. Avoid dropping squares or using them as striking tools, as impact can bend blades or damage reference faces, compromising accuracy permanently.
