Jonathan's Hot Take:

Up-cut spiral bits are my most used bits when I'm trying to clear chips or get a clean edge on the side of the stock furthest from my tool.

These bits provide the HIGHEST VALUE because the Astra Coating makes them last at least 2-4x longer than uncoated bits. This is one of those times that spending a little more upfront saves you a lot of money down the line.

Spiral bits perform 100x better and 100x longer than straight bits. I recommend staying away from straight bits in general, because they dull so much faster and their aggressive cutting profile can be much less safe.

What is an UpCut bit?

UpCut 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.
