Description

This premium 1/4″ compression bit (also known as an up-down bit) is a unique bit for CNC routers. It allows you to cut out your CNC project while leaving both the top and bottom edges of your project clean (eliminates tear-out).

The 1/4″ compression bit can cut the entire depth of 3/4″ material in one pass.

1/4 compression bits are commonly used in place of the 1/4 up-cutting endmill and the down-cutting endmill. They are excellent for use when cutting out plywood at full depth on your CNC woodworking projects.

    Very impressed with the results of this bit! Used it for a raised letter sign I was making out of PVC. Left a VERY clean bottom surface of the pocket!
