3/8″ x 3-1/2” Solid Carbide Flat End Mill with a .375 (3/8″) cutting tip and a 1-1/4″ length of cut.
Our spiral down-cut bits provide a shear cutting edge that leaves a smoother cut than standard router bits. Down cut spiral design provides sharp edges and flat bottoms with minimal chipout.
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.
