Boneham AM00000627 Drill Bushing Pm 6.2 Inch Id

Product Description

The BONEHAM AM00000627 is a press fit headless drill bushing with industry code PM, designed to guide drill bits accurately during machining and fabrication operations. Made from hardened steel with a Rockwell hardness of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. The inside diameter measures 6.2 inches with a tolerance of +0.005/+0.014 mm, ensuring consistent hole placement. The outside diameter of the body measures 12.00 mm and the overall length is 16.00 mm. It is installed by press fit directly into a jig plate or fixture without a head flange, keeping the profile flush with the work surface. Machinists, tool and die makers, and precision fabricators are the primary installers.

This bushing fits standard jig and fixture setups in manufacturing and metalworking environments. The PM industry code designates it as a press fit type without a locking collar, making it suited for permanent or semi-permanent installations in drill jigs. Typical applications include repetitive hole drilling operations in production runs where positional accuracy is critical. It is not renewable, meaning it is pressed into the jig body and replaced by pressing out and installing a new bushing when worn. Complies with ANSI standards for drill bushing geometry and dimensional tolerances.

Key Features

• Hardened steel construction rated 60 to 65 HRC for extended wear life in high-cycle drilling
• Press fit installation method seats securely in jig plate without additional fasteners
• PM industry code headless design sits flush with the jig surface for unobstructed drill entry
• Inside diameter tolerance of +0.005/+0.014 mm supports consistent hole location accuracy
• Meets ANSI standards for drill bushing dimensions and fitment
• Non-renewable design suited for fixed, long-term installation in production jigs

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and machining fixtures requiring a PM-type bushing with a 6.2-inch inside diameter.

Installation Notes

Installation requires a hydraulic or arbor press to seat the bushing flush and square in the jig plate bore. Verify the mating hole in the fixture is machined to the correct interference fit diameter before pressing. Do not hammer the bushing directly, as this can distort the bore geometry. Once installed, the bushing is not intended to be removed and reused.
