What is a DownCut bit?
With a DownCut bit, the advantage is that it’s pushing down on the piece you’re working on, plus it cleanly cuts the top surface. The tradeoff is the waste is pushed back into the cut area instead of being ejected, so we recommend not to cut dados or drill holes with a downcut. These bits are also made to be ran slower – both in revolution or RPM of the bit, and also in spindle movement. That’s because the waste often has nowhere to go, so it is continually being chopped by the sharp flutes.

This bit is the workhorse of my CNC machine. Smooth accurate cuts every time. The Astra coating really helps it hold up to the workload. I do a lot of work with hardwoods and this bit never misses a beat. Love it!

Excellent bits, very sharp and cut cleanly. Can’t say much about the Astra coating as I have not used it very many times just yet.
