Boneham AM00000623 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000623 is a press fit headless drill bushing with industry code PM, designed to guide cutting tools precisely during drilling, reaming, or boring operations. Made from hardened steel with a Rockwell hardness of 60 to 65 HRC, it delivers the wear resistance needed for repeated production use. The bushing installs permanently into a jig plate without a head flange, keeping the top surface flush. It has a 6.25 mm inside diameter with a close tolerance of plus 0.005 to plus 0.014 mm, a 12.00 mm body outside diameter, and a 10.00 mm overall length. Machinists and tool-and-die tradespeople install this type of bushing in drill jigs for consistent hole location in metal fabrication environments.

This bushing is suited for production drilling applications where a permanent, flush-mount guide is required. The PM industry code designates it as a press fit style conforming to ANSI standards, making it a direct fit for standard drill jig plates that accept PM-coded headless bushings. It is used across metalworking, manufacturing, and tooling shops where tight positional tolerance and high cycle life are required. The non-renewable design means it is intended for permanent installation rather than field replacement under load cycles.

Key Features

• Press fit headless design provides a flush top surface in drill jig plates
• Hardened steel construction rated 60 to 65 HRC for extended wear life
• 6.25 mm inside diameter with tolerance of plus 0.005 to plus 0.014 mm for precise tool guidance
• Meets ANSI standards under PM bushing industry code
• 12.00 mm body outside diameter and 10.00 mm overall length for compact installation
• Non-renewable, permanent-installation design

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for standard ANSI-compliant drill jig plates accepting PM-coded bushings with a 12.00 mm body outside diameter.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press to seat the bushing flush into a precision-bored jig plate hole. Ensure the jig plate bore matches the bushing outside diameter tolerance before pressing. Do not hammer the bushing directly, as this can damage the bore alignment or the bushing face. Consult applicable ANSI jig and fixture standards for recommended press fit interference values for the plate material being used.
