Chloe ★★★★★

Pulled a few parts off this after checking with a tenths indicator and it was dead level across the whole surface. The 3-inch thick granite gives it the solid weight you want for layout work without taking up too much bench space.

Julian ★★★★★

The 12x9 surface is surprisingly flat right out of the box — I checked it against my best straightedge and found no deviation. The 3-inch thickness makes it feel rock-solid and stable even on my workbench.

Joshua Z. ★★★★★

The auto-collimator check gives me confidence in this plate's flatness right out of the box. I use it daily for setting up my mill and the 12x9 surface is just right for small parts.
