Boneham AM00000535 Press Fit Drill Bushing Pm 3.75in

Product Description

The BONEHAM AM00000535 is a press fit headless drill bushing with industry code PM, designed to guide drill bits and cutting tools with precision in jig and fixture applications. Machined from steel, this bushing installs without a head flange, sitting flush within the jig plate for applications where a low-profile installation is required. The inside diameter measures 3.75 inches, and the body outside diameter is 7.00 millimeters with an overall length of 12.00 millimeters. It is a non-renewable type, meaning it is permanently pressed into the jig body and is not intended for field exchange without replacing the plate insert.

This bushing is used in precision machining and fabrication environments where repeatable hole location is critical. It fits standard jig plates and drill fixtures in production and toolroom settings. Machinists, toolmakers, and manufacturing maintenance technicians install this type of bushing when setting up multi-operation drill jigs or dedicated tooling fixtures. The headless design makes it appropriate for close-tolerance arrangements where adjacent bushings or workpiece clearance limits the use of flanged styles.

Key Features

• Press fit installation method for permanent, rigid seating in jig plates
• PM industry bushing code for standardized interchangeability across tooling systems
• Steel construction for hardness and wear resistance in repeated drilling operations
• Headless design allows flush mounting where flange clearance is restricted
• Non-renewable type suited for permanent fixture applications

Compatibility

Designed as a standard PM-code press fit headless drill bushing for use in jig plates and drill fixtures requiring a 3.75-inch inside diameter guide bore.

Installation Notes

Press fit bushings are typically installed using an arbor press or hydraulic press with an appropriate driver that contacts the bushing body evenly. Verify jig plate bore tolerance matches the bushing outside diameter before pressing to avoid galling or misalignment. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation without potential damage to the host plate. Follow applicable shop safety and tooling standards when operating pressing equipment.
