Boneham P6416LK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P6416LK is a press fit headless drill bushing manufactured from hardened steel, designed to guide twist drills and reamers with precision in production drilling operations. With a 0.5-inch inside diameter and a 1-inch outside diameter, this bushing presses directly into a jig plate without a locking collar or head flange. The inside diameter holds a tolerance of +0.0001 to +0.0005 inches, ensuring consistent tool guidance and hole location accuracy. Hardness runs 60 to 65 HRC, providing long service life under high-cycle drilling conditions. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is suited for use in drill jigs and fixture plates in both production machining and precision fabrication environments. The headless, press fit design is the correct choice when the bushing must sit flush with the jig plate surface, eliminating any head protrusion that could interfere with workpiece clamping or chip clearance. It is appropriate for ferrous and non-ferrous workpiece materials where repeatable hole location is required across multiple parts. Industry code P identifies the bushing family within standard ANSI drill bushing classification, allowing direct cross-reference by machinists specifying tooling from engineering drawings.

Key Features

• Press fit installation — no collar or locking hardware required
• Headless design sits flush with jig plate surface for unobstructed clamping
• 0.5-inch ID with +0.0001 to +0.0005 inch tolerance for precise drill guidance
• 60 to 65 HRC hardness for extended service life in high-cycle applications
• ANSI-standard bushing industry code P for straightforward engineering cross-reference
• Non-renewable fixed bushing — intended as a permanent press fit installation

Compatibility

Designed as an ANSI-standard press fit headless drill bushing suitable for use in drill jigs and fixture plates that accept a 1-inch outside diameter bushing with a 1-inch overall length.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press fitted with an appropriate driver. The receiving hole in the jig plate must be machined to the correct interference fit before pressing to avoid damage to the bushing bore. Power down all machine tools and secure the jig plate firmly before pressing the bushing into position. Do not drive the bushing with a hammer directly on the bore face, as this will distort the precision ID.
