Boneham PT245FX Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT245FX is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision during machining and fabrication operations. Built from hardened steel with a Rockwell hardness of 60 to 65 HRC, this bushing resists wear and maintains dimensional accuracy under repeated use. The headless design allows it to sit flush with the jig plate surface, making it well-suited for applications where a protruding head would interfere with workpiece clamping or tooling clearance. It is installed by pressing directly into a prepared hole in a drill jig, fixture plate, or template without the need for a locking mechanism.

This bushing is intended for use in drill jigs and fixture plates in metalworking, toolmaking, and precision machining environments. It carries an ANSI-standard industry code P designation, indicating a standard press fit headless type. The 0.1935-inch inside diameter accepts a Number 10 wire gauge drill or equivalent tooling. With an overall length of 5/16 inches and a body outside diameter of 3/8 inches, it fits compact jig layouts where space is limited. Machinists, tool-and-die makers, and jig builders are the primary installers of this component.

Key Features

• Headless press fit design seats flush with jig plate surface for unobstructed clamping
• Hardened steel construction rated 60 to 65 HRC for extended service life under drilling loads
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures consistent tool guidance
• ANSI-standard bushing code P for cross-reference with standard tooling catalogs
• Non-renewable design — intended as a permanent press-in installation
• Compact 5/16-inch overall length suits thin jig plates and tight fixture layouts

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs, fixture plates, and tooling templates requiring a Number 10 wire gauge or 0.1935-inch inside diameter tool guide.

Installation Notes

Installation is performed by tool-and-die makers or machinists using a press or arbor press to seat the bushing flush into a correctly sized and toleranced hole in the jig plate. The receiving hole must be prepared to the appropriate fit tolerance to achieve a secure press fit without distorting the bushing bore. Always de-burr and clean the receiving hole before pressing. Because this is a non-renewable bushing, removal will typically damage either the bushing or the plate, so placement should be confirmed before pressing.
