لوح سطح، جرانيت، 12" × 9" × 3"

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.

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.

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.
