Boneham P565LU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P565LU is a press fit headless drill bushing used to guide drill bits and reamers with precision during machining operations. Manufactured from steel, this bushing features a 35/64-inch inside diameter and a 7/8-inch outside diameter, with an overall length of 5/16 inch. The headless design sits flush with or below the jig plate surface, making it suitable for applications where a protruding head would interfere with workpiece clearance or fixturing. It is installed by press fitting directly into a hardened jig plate without a locking collar or retaining head. Machinists and tool and die professionals install this type of bushing when repeatable hole location accuracy is required across production runs.

This bushing carries the industry code P, which designates its dimensional series within the press fit headless category. It is used in drill jigs, fixture plates, and tooling assemblies in metalworking and machining environments. The non-renewable design means it is intended as a permanent installation rather than a field-replaceable liner. Typical applications include production drilling, reaming, and light boring where the bushing remains fixed in the jig for the life of the tooling program.

Key Features

• Press fit installation — no retaining collar or head required
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for consistent drill guidance
• Headless design allows flush or sub-flush seating in jig plates
• Steel construction provides hardness and wear resistance for repeated drill passes
• Industry code P designation for standard dimensional series compliance
• Non-renewable, permanent-fit design suited for long-run tooling programs

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to industry code P dimensional standards, suitable for use in steel or hardened jig plates requiring a 7/8-inch press fit bore.

Installation Notes

Press fit drill bushings are installed by machinists or toolmakers using an arbor press or hydraulic press; never drive them in with a hammer, as this can crack the jig plate or distort the bushing bore. The receiving hole in the jig plate must be machined to the appropriate press fit tolerance before installation. Ensure all chips and debris are cleared from the bore before pressing to prevent galling. Once installed, the non-renewable design means removal typically damages the bushing and may require the bore to be re-machined or sleeved.
