    These router bits are not square. In other words, the top is not perpendicular to the sides so if they are used for something like a dado or finger joint you will not get a square cut. I have tried several and they were all the same.

    We used this bit in a circle jig to cut 2 thick pieces of poplar. Worked very well and is still sharp after 12 hours of use.

    Initially it was great but if felt like it got dull pretty quickly. Overall it’s still pretty sharp, but the tip is what’s used the most is dull. If they can add some kind of coating just on the tip it will greatly benefit its life. But I also have a WhiteSide brand tool and I feel like it lasts longer.

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
