Boneham P324FT Press Fit Headless Drill Bushing

Product Description

The BONEHAM P324FT is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in metalworking and machining operations. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing provides long service life in high-cycle drilling applications. It features a 3/16 inch (0.1875 inch) inside diameter, a 1/2 inch outside diameter, and a 1/4 inch overall length. The headless design allows for flush installation in drill jigs and fixtures where a protruding flange is not acceptable. Machinists and tooling specialists install this type of bushing in jig plates to maintain hole location accuracy across repeated operations.

This bushing is suited for use in drill jigs, fixture plates, and production tooling setups in both job shop and manufacturing environments. The press fit installation method means the bushing is driven directly into a prepared hole in the jig body without the need for a locking mechanism, making it a permanent, non-renewable installation. The inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures consistent tool guidance. It is appropriate for applications where tight positional tolerances are required across multiple workpieces.

Key Features

• Headless design allows flush installation in drill jig plates and fixtures
• Press fit installation method provides a permanent, secure mount without locking hardware
• Steel construction with 60 to 65 HRC hardness for wear resistance in repeated drilling cycles
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance
• Meets ANSI standards for drill bushing dimensions and performance
• Industry code P classification for press fit headless bushings

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a press fit headless bushing with a 3/16 inch inside diameter and 1/2 inch outside diameter per ANSI standards.

Installation Notes

Installation is performed by machinists or tooling technicians using a press or arbor press to drive the bushing into a correctly sized and reamed hole in the jig plate. The receiving hole must be machined to the appropriate tolerance to achieve proper interference fit before pressing the bushing in. Once installed, this bushing is not designed for removal or renewal. Always verify hole location and diameter before pressing to avoid damage to the bushing or jig body.
