Boneham PT244GF Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT244GF is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under Industry Code P, this bushing features a 0.204-inch inside diameter, a 3/8-inch outside diameter, and a 1/4-inch overall length. Constructed from steel hardened to 60 to 65 HRC, it provides the wear resistance required for repetitive drilling operations. The headless design allows flush mounting in close-tolerance fixtures where a flanged head would interfere. Inside diameter tolerance is held to +0.0001 to +0.0004 inches, meeting ANSI standards for drill bushing accuracy.

This bushing is suited for use in production drilling, reaming, and boring fixtures in machine shops, toolrooms, and manufacturing environments. It is a non-renewable (fixed) bushing intended for permanent press fit installation directly into a drill jig plate or fixture body. Toolmakers and fixture builders are the primary installers. It is appropriate for applications requiring consistent hole location across high-volume part runs where a liner bushing is not needed.

Key Features

• Industry Code P headless press fit design for flush, permanent installation
• Inside diameter tolerance +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for long service life under repeated drilling
• Compact 1/4-inch overall length suits thin jig plates and tight fixture layouts
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable design eliminates bushing retention hardware

Compatibility

Designed as an OEM-style replacement or standard component for drill jigs and fixtures requiring a press fit headless bushing with a 0.204-inch inside diameter and 3/8-inch outside diameter per ANSI specifications.

Installation Notes

Press fit installation requires an arbor press or hydraulic press to seat the bushing flush and square in the fixture plate bore. The mating bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Do not drive the bushing with a hammer, as this can damage the bore geometry or alter concentricity. Removal is not recommended for this non-renewable design; once installed, the bushing is considered permanent.
