Head Press-Fit Bushings Metric (HM)

Quick-Ship Head Press-Fit Bushings Metric (HM)

Heavy-duty metric head press-fit drill bushings. Permanently pressed into the jig plate with integral head for axial load resistance. Used for single-operation drilling/reaming in demanding applications.
Quick-Ship HM bushings handle heavy axial forces. Metric head design provides superior load resistance over flush PM bushings while maintaining permanent installation economy. Perfect for high-force metric production drilling. Head can be exposed or recessed via counterbore for versatile mounting options.

Why choose HM bushings?

Why Head Press-Fit (HM) bushings excel: Integral metric head resists heavy axial loads while permanent press-fit eliminates replacement costs in single-operation tooling.
