Product Information
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. Note: the "length" listed for an HM bushing refers to its overall length, not its length under the head. Complete part numbers for all standard Metric Head Press-Fit Bushings (all standard ID, OD, and length combinations) are listed in the tables below. The Part Configurator link at the top of this page can be used for any HM bushing, either standard or special.
