Boneham SP00003489 Headless Drill Bushing 3/8 in Id

Product Description

The BONEHAM SP00003489 is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It features a 3/8 inch inside diameter, a 3/4 inch body outside diameter, and an overall length of 5/8 inches. The headless profile allows flush mounting in tight fixture layouts where a flanged head would interfere. Installation is permanent press fit, making this a fixed-location guide suitable for high-volume production jig work performed by machinists and toolmakers.

This bushing is suited for use in drill jigs and machining fixtures in manufacturing, fabrication, and toolroom environments. It is appropriate for applications requiring a hardened, wear-resistant guide in ferrous and non-ferrous drilling operations. The ANSI-conforming dimensions make it a standard replacement or new-build component for industrial tooling setups where consistent hole location is critical across production runs.

Key Features

• Press fit installation method for permanent, fixed-position guidance
• Headless design allows flush mounting in confined fixture layouts
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for accurate drill guidance
• Meets ANSI standards for drill bushing dimensions and fitment
• Non-renewable design suited for permanent jig installations

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and machining fixtures requiring a 3/8 inch ID guide bushing with a 3/4 inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press to drive the bushing into the jig plate bore. The receiving hole must be machined to the correct press fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Always verify the jig plate is secured and the machine is de-energized before installing or inspecting drill bushings in active fixtures.
