What To Look For in a Speed Square
The best speed square should be well-machined, durable and accurate. Look for one that is manufactured from a quality aluminium alloy. It should feature a wide base, to make it easier to hold the square tight against timbers. Markings should be precise and easy to read, contrasting sharply with the background colour or finish, and ideally stamped into the aluminium.
For making accurate angle measurements speed squares should feature a notch in the pivot corner. Notches cut out of the scribing section make rip cuts easy to mark out too. Also, look for both imperial and metric scales.
