Boneham PT365IF Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT365IF is a press fit headless drill bushing classified under industry code P. It is machined from steel and designed to guide drill bits with precision in jig and fixture applications. The inside diameter measures 19/64 inches with a close tolerance of +0.0001 to +0.0005 inches, ensuring accurate hole location and repeatable results across production runs. The body outside diameter is 9/16 inches and the overall length is 5/16 inches. Machinists and toolmakers install this bushing directly into a drill jig plate using an interference press fit, eliminating the need for a locking collar or head flange.

This bushing is suited for use in drill jigs, fixtures, and tooling plates in both production machine shops and maintenance environments. Its headless profile allows it to sit flush with the jig plate surface, which is useful in tight clearance setups or multi-station fixtures where a headed bushing would interfere with workpiece travel or clamping. It is a non-renewable design, meaning it is intended for permanent installation rather than field replacement.

Key Features

• Industry code P classification for press fit headless bushings
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance
• Headless design seats flush with jig plate surface
• Steel construction for durability in production drilling applications
• Non-renewable, permanent press fit installation
• Compact 5/16 inch overall length fits thin jig plates

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for steel drill jig plates and fixtures requiring a press fit headless P-series bushing with a 19/64 inch inside diameter and 9/16 inch outside diameter.

Installation Notes

Installation is performed by a machinist or toolmaker using an arbor press or hydraulic press to seat the bushing flush into a precisely reamed jig plate bore. The receiving hole in the jig plate must be reamed to the correct interference fit dimension before pressing to avoid bushing distortion or bore damage. Do not drive the bushing with a hammer directly on the bore face. Once pressed in, this bushing is not designed for removal and reinstallation.
