A compression bit cuts in two directions at once. The short up-cut section at the tip pulls chips up and keeps the bottom face of the sheet clean. The down-cut flutes above it push the top face down. Together they leave clean edges on both faces of plywood and other sheet goods.

This Maker Modus bit has a 3/8" cutting diameter, a 3/8" shank and 2 flutes. The cutting length is 1-1/4", with a 3/16" up-cut section at the tip and a 30° helix angle. It's made from solid carbide with our DuraKeen™ coating, a special coating made to extend edge life, and is built for woodworking on a CNC router.

Good for

These are the typical jobs for a compression bit:

  • Plywood and Baltic birch
  • MDF
  • Melamine and other laminated panels
  • Cabinet and furniture parts cut from sheet goods

Tip for clean edges

Set your cut depth deeper than the 3/16" up-cut section so the down-cut flutes reach the top face. If the cut stays inside the up-cut zone, only the up-cut flutes touch the top face and you lose the compression effect there.
