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.

Daniel Y. ★★★★★

Was a bit nervous about chip clearing on deep passes, but this bit pulls debris out beautifully even at 2 inches deep in hard maple. The Astra coating definitely helps keep it sharp through several runs without any burn marks.

Chloe ★★★★★

Installed this spiral bit today and the AstraHP coating definitely reduced friction—the cuts felt noticeably smoother than my uncoated bits. Cleaned chips perfectly from my ¾″ plywood without any burning or slowdown.

Brian ★★★★☆

Cutting through 3/4" plywood with this bit and the chip evacuation is honestly the best I've seen from a spiral bit. The 2" cut length gives plenty of reach, though I did have to dial the feed rate down a notch to avoid a bit of tear-out on the bottom edge. Still, it's a solid upgrade for my CNC pro
