    This was purchased for cutting a radius through laminate plastic glued to MDF board used for shop made table saw miter sled. The down spiral cut left a very smooth, clean edge in the thin plastic, exactly as desired. It also left a clean, smooth edge on the MDF and a plastic liner glued to the underside as the surface contacting the table saw. If interested, this highly accurate miter build is illustrated by the designer on YouTube. Search for Making a Super Accurate Miter Gauge.

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
