What is an UpCut bit?

Up-cut bits allow for rapid cuts since the tool clears the chips away from the material.  While Ideal for cutting thicker materials, this type of tool is not recommended for thinner or softer materials. They are more likely to tear the top surface with the cutting edges because they’re pulling the wood fibers up while cutting. When cutting laminated materials, such as plywood with a thin top veneer, that can matter a lot. This type of bit is used whenever the best finish is needed on the bottom side of a part.

Lucy ★★★★★

I’ve been using this bit on ¾” plywood and the AstraHP coating definitely keeps it cooler than standard uncoated bits. The up-cut design clears waste fast, though I do need to watch for tear-out on the top surface.

Eva ★★★★★

The triple flute geometry cleared chips out of a 2-inch cut in hardwood without a single pause for cleanup. The AstraHP coating kept the bit cool enough that I didn't have to babysit the pass speed.

Ruby ★★★★★

I was nervous about heat buildup on deep cuts, but the up-cut spiral design clears chips so fast there’s almost no friction. This bit just blasts through 1-inch plywood like butter.
