Shipping Details

One of the most popular squares in the Swanson® lineup, the 12-inch Combination Square features CNC-machined working surfaces for more reliable accuracy as well as 45° and 90° marks. This Square is the perfect choice for common carpentry tasks such as gauging depth, scribing lines for ripping material, mitering, and drawing notches. The blade is made from stainless steel and includes precision-etched gradations in both US and metric units that are accurate to within 0.001 inch. The handle holds a hardened removable scribe for marking surfaces as you work, and its impact-resistant acrylic vial outperforms less durable tube-type vials. Made with the professional in mind, this tool is a carpentry classic.

12 inch stainless steel blade features precision-etched black gradations, includes brass hardware

Not square

Would Not Recommend

After a few uses. It is not square. I checked it against a speed square and regular steel square. It was off by 1/16 of an inch at 12 inches.

Beware - Fragile Parts

Would Not Recommend

This was a functionally solid combination square, but after being dropped the pin that holds the ruler snapped, rending it useless. Getting replacement parts doesn't seem to be possible, which is quite the bummer!

Heavy Duty but loose

Would Not Recommend

Bought this because it felt solid and it is. I thought of the Swanson name as quality. The problem that I have is tightening the square. The nut tightens down but the square still wiggles. It doesn't wiggle a lot but it does wiggle. I would have returned it but I lost my receipt.
