Head Press-Fit Bushings (H)

Quick-Ship Head Press-Fit Bushings (H)

Heavy-duty 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 H bushings handle heavy axial forces. Head design provides superior load resistance over flush P bushings while maintaining permanent installation economy. Perfect for high-force production drilling. Head can be exposed or recessed via counterbore for versatile mounting options.

Why choose H bushings?

Why Head Press-Fit (H) bushings excel: Integral head resists heavy axial loads while permanent press-fit eliminates replacement costs in single-operation tooling.
  • Permanent press-fit with head
  • Heavy axial load resistance
  • Head exposed or recessed mounting
  • Economical permanent solution
  • Single operation optimized
  • No-Counterbore (-NCB) option

Applications

High-force single-step drilling/reaming. Ideal for production jigs requiring head retention against heavy downward forces.
