01AUTOMOTIVE REPAIR & SPECIALITY TOOLS

Precision in every angle

The bench is quiet until the tool arrives. Its black finish sits firmly among the clamps and calipers, a compact instrument of order waiting to define the shape of the work ahead.

This combination square measures up to 300mm, handling right angles, 45-degree slopes, and depths with equal confidence. It suits engineers, machinists, and makers who value exactness over speed.

02MATERIALS

Stainless steel meets zinc alloy

The ruler is cut from stainless steel, while the sliding base is cast from zinc alloy. This pairing balances rigidity with weight, ensuring the tool holds its position without feeling cumbersome. The materials are chosen for longevity, resisting the wear that plagues softer plastics or painted metals.

03CALIBRATION

Laser-etched lines that stay clear

Unlike printed scales that smudge or peel, this square features laser-engraved markings. The etching creates a physical depth in the metal, making the numbers legible even under harsh workshop lighting or after years of use. The clarity ensures that every millimetre is read correctly, reducing guesswork during critical cuts.

04FUNCTION

Six modes of measurement

Adjustable across a 300mm range, the square shifts between measuring right angles, 45-degree angles, 45-degree slopes, length, depth, and width. A built-in level gauge adds another layer of precision, allowing the user to verify horizontal or vertical alignment directly on the tool rather than relying on external references.

05DETAILS

The black edition's added utility

While other colours offer standard functionality, the black variant includes an extra center gauge and protractor. These additions expand the tool’s versatility, allowing for more complex angular checks without needing separate instruments. The detachable design keeps it portable, ready for travel between job sites or storage in a compact drawer.
