Boneham AM00000169 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000169 is a press fit headless drill bushing designed to guide cutting tools with precision during drilling operations. Manufactured from steel, this bushing carries the industry code HM and features an inside diameter of 4.8 inches, a body outside diameter of 8.00 mm, and an overall length of 8.00 mm. It installs without a head flange, seating flush within the jig plate for applications where a low-profile installation is required. Machinists and toolmakers rely on this type of bushing to maintain hole location accuracy across repeated drilling cycles in production jigs and fixtures.

This bushing is suited for use in drill jig assemblies across light manufacturing, precision machining, and toolroom environments. Its press fit installation method means it is pressed directly into a reamed hole in the jig plate, providing a secure, non-rotating fit without the need for locking hardware. The non-renewable design makes it appropriate for permanent installations where the bushing is not expected to be replaced during normal production runs.

Key Features

• Press fit installation method seats the bushing securely without additional fasteners
• Headless design provides a flush, low-profile fit in jig plates
• Steel construction offers durability in repetitive drilling applications
• HM industry code for straightforward cross-referencing and replacement sourcing
• Non-renewable bushing suited for permanent jig plate installations

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing conforming to HM industry code standards for press fit headless drill jig bushings.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to seat the bushing into a properly reamed hole in the jig plate. The receiving hole must be reamed to the correct interference fit tolerance for the outside diameter before pressing to avoid damage to the bushing or the plate. Always verify that the jig plate is fully supported during pressing to prevent distortion. Once pressed in, the bushing should be inspected for flush seating and concentricity before the jig is placed into service.
