When to choose it

The HC4122 is a compression cutter for a nominal 3/8-inch cut. It combines opposing flute directions and requires a router or machine with the exact 3/8-inch collet size.

Check the documented machine setup and where the flute transition falls in the stock. A similar-looking 3/8-inch cutter can have a half-inch shank or a different flute direction.
