305mm Combination Square with Spirit Level and Scriber — 12" Metric & Imperial Graduated Rule with Machine Milled Faces

There are tools you pick up once in a while, and then there are tools you reach for on almost every job. A good combination square falls firmly into the second category. This 305mm version is built for people who need accurate, repeatable measurements across a range of tasks without swapping between half a dozen different tools.

The stainless steel blade runs to 305mm (12 inches) and is graduated on both sides in metric and imperial, so whether you're working in millimetres or inches, the markings are clear and easy to read. The faces are machine milled for a flat, true edge — which matters when you're marking out for cuts or checking for squareness, because any variation in the blade will carry through directly into your work.

The cast head slides along the blade and locks firmly in position wherever you need it. Set it at the end for 90° work, flip your approach for internal angles, or use the 45° face when you're cutting mitres or marking chamfers. The built-in spirit level vial in the head means you can check horizontal and vertical alignment without reaching for a separate level, and the scriber stored in the handle is right there whenever you need to mark a line cleanly on metal or timber.

This is the kind of tool that feels right in the hand from the first time you use it — substantial without being heavy, precise without being fiddly.
