Boneham P134CG Press Fit Headless Drill Bushing

Product Description

The BONEHAM P134CG is a Type P press fit headless drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. With an inside diameter of 0.0785 inches (No. 47 wire gauge) and an inside diameter tolerance of +0.0001 to +0.0004 inches, this bushing holds tight positional accuracy across repeated drilling cycles. The body outside diameter is 13/64 inches and the overall length is 1/4 inch. Constructed from steel, it is pressed directly into a drill jig plate without a locking head, keeping the tool plate surface flush. Machinists, toolmakers, and precision fabricators install this component during jig assembly or tooling maintenance.

This bushing is suited for light-duty drill jig applications where a flush, headless profile is required and the bushing is intended to remain permanently in place. It fits production environments and job-shop settings where consistent hole location is critical across multiple workpieces. The Type P designation indicates a standard press fit bushing per tooling industry classifications, making it a straightforward replacement or initial build component for drill jig fixtures in metalworking and precision machining operations.

Key Features

• Type P press fit design — seats permanently in jig plate without a locking collar
• Headless profile keeps jig plate surface flush for unobstructed workpiece clamping
• Inside diameter of 0.0785 inches matches No. 47 wire gauge drill size
• Tight ID tolerance of +0.0001 to +0.0004 inches ensures consistent drill guidance
• Steel construction provides durability under repeated drilling cycles
• Compact 1/4 inch overall length suits thin jig plate applications

Compatibility

Designed as an OEM-style replacement or new-build component for steel drill jig plates requiring a Type P press fit headless bushing with a 0.0785 inch inside diameter and 13/64 inch outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinist personnel using an arbor press or hydraulic press — never driven in with a hammer, as impact force can distort the bore geometry. The receiving hole in the jig plate must be machined to the correct tolerance to achieve proper press fit interference. Inspect the bushing bore and mating hole for burrs or contamination before installation. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation.
