Product Details

  • Hardened to HRC 40+
  • Surface ground on the front and back
  • Surface ground on the step for parallelism and accurate height. 1.1" +/- 0.0002"
  • 1/4-20 threaded hole on both sides for workstops
  • Grind gap machined with a ball endmill vs a square, resulting in a much smaller stress concentration and greater rigidity
