How Does It Work?
As the tool is being fed into the part, the blade(s) start cutting once the tip of the tool reaches the part. The tool continues to be fed until the desired countersink size is achieved, then the operator must rapid the tool out of the part. The GH-K tool provides precision cut countersinks without chatter due to the shallow radial clearance which may require controlled feed rates. Shims can be added when more aggressive feed rates are required.
