Boneham H3222IF Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H3222IF is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 19/64-inch inside diameter and a 1/2-inch body outside diameter, with a length under the head of 1-3/8 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. The inside diameter tolerance is held to +0.0001 to +0.0005 inches, providing consistent hole location accuracy. It is a permanent, non-renewable bushing installed by press fit and is not designed for in-field removal and replacement.

This bushing is suited for production drilling, reaming, and boring operations where a fixed guide bushing is required. It is used in drill jigs and fixture plates across manufacturing, toolroom, and machinist applications. The counterbored design accommodates headed configurations, and the head keeps the bushing seated against the jig plate during operation. Machinists and toolmakers working to ANSI standards will find this bushing dimensionally compliant for standard jig plate layouts.

Key Features

• Press fit installation for permanent, fixed positioning in jig plates
• Type H headed design with a 39/64-inch head outside diameter and 7/32-inch head height
• Steel construction hardened to 60 to 65 HRC for extended wear resistance
• Inside diameter tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Counterbored to accept the headed bushing profile flush or recessed in the plate
• Meets ANSI standards for drill bushing dimensions

Compatibility

Designed as a standard ANSI Type H press fit headed drill bushing for use in drill jigs and fixture plates requiring a permanent, non-renewable bushing with a 19/64-inch bore and 1/2-inch body outside diameter.

Installation Notes

Installation is performed by a machinist or toolmaker using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The plate bore must be machined to the appropriate interference fit tolerance before installation. Once pressed in, this bushing is not intended to be removed or replaced. Verify jig plate material and bore finish before pressing to avoid bushing damage or distortion.
