The Mold Masher’s introduction in 1984 has proven to be a quantum leap forward in ball nose end mill technology. Its role has been to more fully utilize and extend the benefits of CNC generated tool paths now extensively used in our metal working industries.

Unlike its known competitors, the Masher is available in 5 degree positive and 5 degree negative axial rake configurations. It employs two identical inserts each extending the cutting edge to centerline. The inserts dovetail into the end mill body ensuring no Masher insert will ever be torn from its pocket no matter how heavy the cut. (The inserts seat against a carbide shim which dissipates the bearing load, thus greatly extending the tool body life.) This rugged construction philosophy has earned a reputation as the most effective ball end mill in the market.
