## Description

The original Swanson Speed Square has been an indispensable tool for tradesmen for nearly a century. Swanson’s Speed Trim Square has all the great features you’ve always counted on, like the patented 3½ in. Diamond mark and fade-resistant easy-read markings but we’ve taken it up a notch. To make accurate layouts even easier, there’s a scribe bar with guides milled every 1/8 in. Also, drilling holes centered on 3/4 in. stock couldn’t be simpler thanks to a hole milled 3/8 in. from the inside edge, right-sized for self-centering drill bits. And its built to last a lifetime, proudly made in the USA with high-grade aluminum alloy construction. The new Swanson Speed Trim Square’s convenient fit, features, and patent pending design make it a truly must-have tool for cabinetry, moulding, trim and so much more.

Review: Been after one for agers - This is spot on. I’ve been after a small speed square for months but this is the first one that has been a reasonable price. Well made, no sharp edges and it’s square! Perfect for the smaller jobs and easy to carry in a pocket or pouch.
Review: Amazing quality tools - Really nice quality and convenient size! Just wish they made a metric version

### ⭐⭐⭐⭐⭐ Amazing quality tools

### ⭐⭐⭐⭐⭐ You didn’t know you need one!

Speed squares are those tools that once in your life you never want to lose. A 4.5inch (11.5cm) one even more so, Made of high end and thick aluminium so they are tough. Multiple uses for DIY - great for drawing consistent lines, aligning tools, cutting straight etc. Personally a metric version would be great, but the usefulness of a small robust triangle can’t be underestimated despite its form of measurement. Even if you’re not big on DIY, buy one a throw it in your ‘things’ draw. It’ll be used more than you think. These will last a lifetime, so brilliant value for money.
