Boneham P1312DA Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P1312DA is a press fit headless drill bushing used to guide drill bits and cutting tools with precision in metalworking and machining applications. It carries an industry code of P and features a 0.0995-inch inside diameter, a 13/64-inch body outside diameter, and a 3/4-inch overall length. The headless design allows the bushing to sit flush within a jig plate without a protruding collar. Made from steel, it provides durable wear resistance under repeated drilling cycles. Machinists and tool-and-die technicians install this type of bushing directly into drill jig plates to maintain consistent hole location and improve accuracy across production runs.

This bushing is suited for use in drill jig assemblies in precision machining environments, including tool rooms, production floors, and fabrication shops. The press fit installation method means the bushing is driven into a prepared hole in the jig body and is intended to remain fixed in place during service. It is not designed as a renewable or liner-style bushing. The inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures consistent guidance for the corresponding drill wire gauge, listed as wire size number 39.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-use press fit headless drill bushing for standard drill jig plates requiring a P-series industry-code bushing with a 0.0995-inch inside diameter and 13/64-inch outside diameter.

Installation Notes

A licensed machinist or toolmaker should install this bushing using an arbor press or suitable pressing fixture to achieve proper seating depth without damaging the bore. The receiving hole in the jig plate must be machined to the appropriate press fit tolerance before installation. Do not hammer the bushing in freehand, as this can distort the bore or damage the jig plate. Once pressed in, this bushing is not intended for removal and reuse.
