Boneham P135CK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P135CK is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Carrying the industry P bushing code, it features an inside diameter of 0.082 inches (wire size 45) with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 13/64 inches, and an overall length of 5/16 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It is installed by machinists and toolmakers who require repeatable hole location accuracy in production and prototype environments.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups where a permanent, non-renewable guide bushing is required. The headless profile keeps the bushing flush with the jig plate surface, making it appropriate for close-tolerance work where a flanged head would interfere with workpiece seating or tool travel. It conforms to ANSI standards and is a direct fit wherever a P-series press fit headless bushing is specified.

Key Features

• Press fit installation method for a secure, permanent seat in the jig plate
• Headless design sits flush with the plate surface, eliminating interference with workpieces
• Inside diameter tolerance of +0.0001 to +0.0004 inches for consistent tool guidance
• Steel construction hardened to 60 to 65 HRC for long service life under repeated drilling
• Conforms to ANSI standards for P-series drill bushings
• Non-renewable design suitable for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-installation fit for drill jigs and fixtures requiring a P-series press fit headless drill bushing per ANSI standards.

Installation Notes

Installation is typically performed by a toolmaker or machinist using an arbor press to drive the bushing into a reamed or precision-bored hole in the jig plate. The mating hole in the plate must be machined to the correct press fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Always verify hole diameter and surface finish before pressing to avoid bushing damage or distortion.
