    Used this on a recent desk project. Using several passes with this bit I was able to get nice clean cuts. The bit is very sharp so handling with care is needed.

Down-Cut Bit

  • Down-cut bit leaves a clean top edge but a rough bottom edge
  • It is great for cutting shallow dados, rabbets, and visible slots. When cutting dados or grooves with a down cut bit, be sure to slow the feed rate to allow more time for chip removal.

UP-Cut Bit

  • Up-cut bit leaves a smooth bottom edge but a rough top edge
  • The up cut is better at evacuating chips, Ideal for mortise and tenons, grooving, slotting or routing deep blind holes. It performs faster cutting while pulling the chips up.

Compression Bit

  • Compression bit cut both top and bottom cleanly, Its spiral action pulls both sides into the center of the bit where it ejects out of the side.
  • Through cuts in harwoods, softwoods, plywood, melamine, and other veneers
