A workshop measuring tool designed for precise 45° and 90° marking and reliable measurements. Carpenters and engineers will appreciate faster setups and fewer mistakes when using Auyuiiy Combination Square. Does the combination of durability and multifunction use make it essential for everyday woodworking?

⚡ At a Glance
  • Measurement Accuracy: Laser-engraved graduations on a 300 mm / 12 inch stainless steel ruler for clear, repeatable readings
  • Best for: Carpenters, engineers and hobby woodworkers who need reliable 45°/90° marking and layout work
  • Not ideal for: Tasks requiring digital readouts or measurements beyond 300 mm

A 300 mm stainless steel ruler mates with an adjustable zinc-alloy angle head for 45° and 90° layouts. Built-in level and metal scriber add versatility for marking, checking depth and levelling.


Precise 45° and 90° marking – thanks to adjustable square head and laser-engraved ruler

An adjustable angle holder locks onto a 300 mm stainless steel ruler, while laser-engraved graduations keep millimetre and inch markings crisp and easy to read. Two-sided scale gives metric and imperial measurements on the same edge.

Accurate right-angle layouts become routine, so lines align correctly and cut pieces fit together more reliably.

Versatile layout and checking – with built-in bubble level and metal scriber

A small bubble level is integrated into the head for quick horizontal or vertical checks, and a metal scriber stores in the head for marking directly from the ruler. The head also converts the assembly into a depth gauge.

Fast on-site levelling and direct scribing eliminate the need to swap tools, speeding up setup and reducing errors.

Workshop-grade durability – thanks to stainless steel ruler and zinc alloy angle holder

Stainless steel construction for the ruler resists wear and retains straight edges, while a zinc alloy angle holder resists corrosion and resists deformation under normal workshop use. Smooth finish prevents snagging on timber.

Long-term resilience keeps calibration stable and avoids frequent replacements, so accuracy holds up across many projects.

❓ Frequently Asked Questions

Q: How accurate are the angle and length markings?

A: Laser-engraved graduations and a locking adjustable head produce clear centimetre and inch markings, delivering reliable 45° and 90° accuracy as reflected in user feedback.

Q: Can it measure in both metric and imperial units?

A: Yes, the ruler is dual-sided with 300 mm on one edge and 12 inch markings on the other, so both systems are available without conversion.

Q: Is the build suitable for workshop use and resistant to rust?

A: Stainless steel for the ruler and a zinc alloy angle holder resist corrosion and maintain shape under typical workshop conditions.

🏆 Our Verdict

Ideal for carpenters, engineers and hobby woodworkers who rely on accurate layout and repeatable measurements. Clear laser-engraved scales combined with an adjustable zinc-alloy head, bubble level and scriber make the tool notably versatile for on-site marking and checking. Durable materials and practical functions suggest strong long-term value for frequent use.
