Boneham P1616DQ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P1616DQ is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel, this bushing features a 0.116 inch inside diameter, a 1/4 inch outside diameter, and a 1 inch overall length. The headless design allows flush seating in jig plates where a protruding head would interfere with workpiece clearance. It is installed by pressing directly into a hardened jig plate bore, where it remains fixed during production runs without the need for a liner bushing. Machinists, tool and die makers, and fixture builders install this type of bushing when repeatable hole location accuracy is required across multiple workpieces.

This bushing is suited for use in drill jig fixtures in metal fabrication, machining, and precision manufacturing environments. Its industry code P classification aligns with standard press fit headless bushing dimensions, making it a direct fit in applications that call for a P-series bushing. The counterbored construction and tight inside diameter tolerance of +0.0001 to +0.0004 inches support close-tolerance drilling operations where positional accuracy is critical. It is appropriate for both short-run and production jig applications where the bushing is pressed in permanently rather than changed between operations.

Key Features

• Press fit installation for permanent, non-rotating seating in jig plate bores
• Headless design allows flush mounting where head clearance is not available
• Inside diameter tolerance of +0.0001 to +0.0004 inches for close-tolerance tool guidance
• Counterbored construction per P-series industry standards
• Steel construction for wear resistance in production drilling applications
• Non-renewable design intended for permanent press fit installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig fixtures requiring a P-series press fit headless drill bushing with a 0.116 inch inside diameter and a 1/4 inch outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush with the jig plate surface. The receiving bore in the jig plate must be machined to the appropriate tolerance to achieve the correct interference fit. Inspect the bore and bushing for burrs or debris before pressing to avoid misalignment or damage to the bushing. Once pressed in, this bushing is not intended for removal or replacement.
