PEC squares are known for their engineered precision and durability. The fully hardened and tempered 100mm blade has an easy-to-read satin chrome finish with metric graduations on both sides (mm and .5mm).
Jonathan’s Hot Take:
A good square is the most important tool in your shop, and the FIRST high quality tool you should buy. I’ve carried PEC squares for years. They are among the best of the best, and have manufactured squares for top brands like Mitutoyo, Brown and Sharpe and Lee Valley.
The PEC double square has extreme tolerances (within .0015”), ensuring precision and accuracy. And the graduations are photo-etched, giving it a tactile feel and making it easy to set a marking gauge, dividers, or knife line.
I use my double square for all kinds of tasks, like laying out joinery, checking for waste in dovetails and mortises, and setting the blade on my table saw.
To top it off, PEC is in our own backyard, just 2 hours away from KM Tools headquarters.
