Boneham P566LX Press Fit Headless Drill Bushing

Product Description

The BONEHAM P566LX is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards, this Type P bushing features a 0.5625 inch (9/16 inch) inside diameter and a 7/8 inch outside diameter, with an overall length of 3/8 inch. Manufactured from steel and hardened to 60 to 65 HRC, it delivers consistent bore guidance and resists wear under repeated drilling cycles. The headless profile allows flush installation in close-tolerance jig plates. Machinists, toolmakers, and production fixture builders install this bushing where repeatable hole location is critical.

This bushing is suited for precision drilling, reaming, and boring operations in production and maintenance environments. It installs directly into a prepared jig plate bore using a press fit, eliminating the need for retaining screws or locking collars. The Type P designation follows standard ANSI bushing coding, making it a straightforward replacement or initial-fit component in any fixture that calls for a P-series headless press fit bushing with 9/16 inch ID and 7/8 inch OD.

Key Features

• Press fit installation — no locking hardware required
• Headless design allows flush, low-profile seating in jig plates
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• ANSI-compliant Type P bushing coding for standardized fixture design
• Non-renewable design optimized for permanent press-in installations

Compatibility

Designed as a standard ANSI Type P press fit headless drill bushing for use in jig plates and fixture assemblies requiring a 9/16 inch ID and 7/8 inch OD bushing bore.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press — never drive this bushing with a hammer, as uneven force can distort the bore geometry. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before pressing the bushing flush. Verify bore alignment before applying press force. No field modification of the inside diameter is recommended after installation.
