Boneham PT3610ID Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT3610ID is a headless press fit drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing carries industry code P and features an inside diameter of 0.295 inches with a tight tolerance of +0.0001 to +0.0005 inches, an outside diameter of 9/16 inches, and an overall length of 5/8 inches. The headless profile sits flush with the jig plate surface, making it well-suited for applications where a raised flange would interfere with workpiece seating or clamping. It is installed by pressing directly into a prepared hole in the drill jig body.

This bushing is used in production drilling, reaming, and boring operations where repeatable hole location is required. It is a standard fixed bushing — non-renewable — meaning it is intended to remain permanently in the jig once installed. Machinists and tool-and-die professionals select this style when the jig will run a single operation at a given station. The 0.295 inches inside diameter corresponds to letter size M drill and accommodates wire gauge size P tooling.

Key Features

• Press fit installation method — no fasteners or locking rings required
• Headless design sits flush with jig plate for unobstructed workpiece contact
• Inside diameter tolerance of +0.0001 to +0.0005 inches for consistent tool guidance
• Steel construction for durability in repetitive drilling cycles
• Non-renewable fixed bushing — permanent installation in jig body
• Inside diameter 0.295 inches corresponds to letter size M and wire gauge P

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for drill jigs and fixtures requiring a headless press fit bushing with a 0.295 inches inside diameter and 9/16 inches outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a properly toleranced bore in the jig plate. The receiving hole in the jig body must be machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or improper seating. Do not drive the bushing in with an impact hammer, as this can distort the inside diameter. Verify inside diameter after installation to confirm the bore has not closed beyond the specified tolerance range.
