1/8″ Flat Compression End Mill (2pcs)





These 1/8″ Compression End Mills offer the best of downcut and upcut bits, allowing for the use of upcut flutes on the bottom part of your cut and the use of downcut flutes on the top surface of your material.

Compression bits are excellent for projects that use materials that are prone to fuzziness or tearout on their edges such as plywood and pine.

This item contains two compression end mills per package.
