Push Block CNC Work Hold Clamps

To set up your spoil board to use these clamps, create a grid of 2in holes on center. It is recommended to do a test of 4 holes in scrap to ensure proper alignment in the vertical and horizontal positions. Do not use an endmill to drill the holes. What I used and is the suggested bit to use, the Lightning Series ¼" Carbide Drill form IDC Woodcraft.
