Boneham P566LP Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P566LP is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. Built to industry code P, this bushing features a 33/64-inch inside diameter and a 7/8-inch body outside diameter, with an overall length of 3/8 inch. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance needed for repetitive production drilling in jig and fixture applications. The headless design keeps the bushing flush with the jig plate surface, which is critical in tight-clearance setups. Machinists and toolmakers install this bushing type in drill jigs on production floors and job shops.

The P566LP suits applications where a permanent, non-renewable press fit bushing is required. It is pressed directly into a jig plate or fixture body and is intended to remain in place for the life of the tooling. Typical use cases include high-volume hole-location drilling on metal workpieces where consistent tool guidance and positional accuracy are essential. This bushing conforms to ANSI standards, making it compatible with standardized drill jig systems across manufacturing environments.

Key Features

• Press fit installation method for secure, permanent retention in jig plate bores
• Headless design allows flush seating with the jig plate surface
• Steel construction hardened to 60 to 65 HRC for long service life under repeated tool contact
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Conforms to ANSI standards for dimensional interchangeability
• Non-renewable design optimized for permanent fixture installations

Compatibility

Designed as a permanent press fit replacement or new-installation bushing for standardized drill jigs and fixtures conforming to ANSI bushing industry code P specifications.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinist tradespeople using an arbor press or hydraulic press to drive the bushing squarely into a prepared bore. The receiving bore should be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Ensure all workpiece clamping and fixturing is secure before beginning drilling operations through the bushing.
