Boneham AM00000674 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000674 is a press fit headless drill bushing with industry code PM, designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. Manufactured from steel, this bushing is pressed directly into a jig plate without a head flange, keeping the top surface flush. The inside diameter measures 7.6 inches, the body outside diameter is 12.00 millimeters, and the overall bushing length is 16.00 millimeters. It is installed permanently and is not renewable. At 0.37 pounds, it is a compact, single-piece component suited for fixed drill jig applications where repeatable hole location accuracy is required.

This bushing is used in machine shops, tooling rooms, and light manufacturing environments where drill jig fixtures must guide tooling to consistent locations across repeated production runs. The headless press fit design is common in applications where a flush top surface is required or where clearance above the jig plate is limited. Installation is performed by pressing the bushing into a prepared hole in a hardened or unhardened jig plate. It is not intended for applications requiring bushing replacement between production runs.

Key Features

• Press fit installation method — no head flange, flush top surface
• Industry code PM designation for standard drill bushing classification
• Inside diameter of 7.6 inches for precise tool guidance
• Steel construction for durability in repetitive drilling applications
• Non-renewable design for permanent fixture installations
• Compact form factor at 0.37 pounds

Compatibility

Designed as a standard PM-code press fit headless drill bushing for use in machining jig fixtures where a permanently installed, flush-mount drill guide is required.

Installation Notes

Installation is typically performed by a machinist or tooling technician using an arbor press or hydraulic press to seat the bushing into a correctly sized receiver hole in the jig plate. The receiving hole should be machined to the appropriate tolerance for a press fit prior to installation. Ensure all machinery is de-energized and the jig plate is secured before pressing. Once installed, this bushing is not designed to be removed and replaced during normal service.
