The flutes are designed to push the chips downward and they also help with fraying and chipping on your work piece. This tool work really well for wood and even on plastics and aluminum. The cutting tip diameter is 3/8″ and the length of cut is 1-1/4″.
These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as extended tool life & increased lubricity in abrasive material.
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 used 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.
