Description
Quick-Ship Head Press-Fit Bushings-Metric
Metric version of our popular H bushing. HM bushings are permanently pressed into the jig plate. They are generally used for single-operation drilling or reaming, when you do not expect to replace bushings during the tooling’s lifetime. The head can be left exposed, or recessed by counterboring the installation hole.
