Toolzone 12″ Heavy Duty Aluminium Speed Square Review

Based in Devon in the heart of the South West, Toolzone have made a handy speed triangle for making quick and accurate perpendicular lines on a range of sheet materials. Made from robust aluminium and finished in matte black for quick reading and weather resistance, the Toolzone 12″ Heavy Duty Aluminium Speed Square is probably the best speed square UK made.

What sets this heavy square tool apart from the competition is that it’s a metric speed square. Seeing as they’re a US invention, the majority of carpenters squares are imperial only, which makes it harder to use for those of us used to metric measurements. It’s a full-size framing square that you’ll use all the time.
