Boneham AM00000132 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000132 is a press fit headless drill bushing with an HM industry code, designed to guide cutting tools accurately during drilling operations. It installs without a head flush into a jig plate or fixture, providing a clean, low-profile surface that does not interfere with workpiece clamping. Manufactured from steel, this bushing offers the hardness and wear resistance required for repeated drilling cycles. With an inside diameter of 3.8 inches, a body outside diameter of approximately 0.276 inches (7.00 mm), and an overall length of approximately 0.630 inches (16.00 mm), it fits standard drill jig applications. Machinists, tool and die makers, and fixture builders are the primary installers.

This bushing is suited for use in drill jigs and production fixtures in both job shop and high-volume manufacturing environments. It is pressed directly into a prepared hole in the jig plate, seating flush with the plate surface. The headless profile makes it appropriate for applications where a protruding flange would interfere with part loading or clamping. The HM industry code designation allows straightforward cross-referencing with standard drill bushing catalogs for replacement or fixture maintenance.

Key Features

• Press fit installation method seats the bushing securely without additional fasteners
• Headless design provides a flush, low-profile surface for unobstructed workpiece clamping
• HM industry code classification for standard catalog cross-referencing
• Steel construction delivers hardness and wear resistance for repeated drilling cycles
• Non-renewable design intended as a permanent fixture component

Compatibility

Designed as an OEM-style replacement or new-installation component for standard drill jig fixtures using HM-series press fit headless drill bushings.

Installation Notes

Installation is performed by pressing the bushing into a precision-reamed hole in the jig plate using an arbor press or hydraulic press. Ensure the receiving hole is reamed to the correct interference fit tolerance before pressing to avoid bushing distortion. The bushing should be driven straight and seated fully flush with the plate surface. Once pressed in, the bushing is not intended to be removed and reused.
