Boneham AM00000508 Drill Bushing Pm 24.5 in Id Steel

Product Description

The BONEHAM AM00000508 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. This PM-coded bushing is manufactured from hardened steel with a hardness rating of 60 to 65 HRC, providing wear resistance during repeated drilling operations. It features a 24.5-inch inside diameter and is installed by pressing directly into a prepared bore in the jig plate, requiring no locking collar or head flange. Machinists, toolmakers, and fixture builders rely on this type of bushing to maintain consistent hole location and drill alignment across production runs.

This bushing is suited for use in drill jigs, production fixtures, and tooling plates where headless installation is required to keep the top surface flush. The PM industry code designates it as a press fit type per standard bushing classification. It conforms to ANSI standards, making it compatible with standard jig plate bores dimensioned to accept PM-series bushings. Applications include metalworking, precision machining, and automated drilling setups in both job shop and production environments.

Key Features

• Press fit headless design - installs flush with jig plate surface, no head flange required
• Hardened steel construction, 60 to 65 HRC for extended wear life
• 24.5-inch inside diameter with inside diameter tolerance of +0.007/+0.020 mm
• Body outside diameter of 35.00 mm and overall bushing length of 45.00 mm
• Non-renewable design - intended as a permanent installation within the jig plate
• Conforms to ANSI standards for PM-series drill bushings

Compatibility

Designed as an OEM-style replacement and standard fitment for drill jigs and fixtures requiring a PM-coded press fit headless drill bushing per ANSI specifications.

Installation Notes

Installation is performed by toolmakers or machinist trades using an arbor press or hydraulic press to seat the bushing into a precision-bored hole in the jig plate. The bore in the receiving plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this non-renewable bushing is not designed for removal and replacement during service. Always verify bore diameter and surface finish before pressing the bushing into position to avoid damage to the bushing or the jig plate.
