Boneham AM00000575 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000575 is a press fit headless drill bushing manufactured to guide drill bits with precision in jig and fixture applications. Designated under industry code PM, this bushing installs without a retaining head, seating flush with the jig plate surface for a clean, low-profile installation. The inside diameter measures 4.7 inches, with a body outside diameter of 8.00 mm and an overall bushing length of 8.00 mm. Constructed from steel hardened to 60 to 65 HRC, the AM00000575 delivers the wear resistance and dimensional stability required for repetitive production drilling operations. It is a non-renewable design and is not counterbored.

This bushing is suited for use in drill jigs and fixture plates in metalworking and machining environments. The press fit installation method makes it appropriate for permanent or semi-permanent fixture setups where bushing removal between operations is not required. Machine shop technicians and toolmakers install this type of bushing in production settings where hole location accuracy and drill guidance consistency are critical. It conforms to ANSI standards, making it compatible with standard jig bushing tooling and fixture design practices.

Key Features

• Press fit installation method for permanent, flush-mount seating in jig plates
• PM industry code designation per ANSI standards
• 4.7-inch inside diameter with a tight inside diameter tolerance of +0.004 to +0.012 mm
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Headless, non-counterbored design for low-profile flush installation
• Non-renewable bushing design suited for fixed production jig setups

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard ANSI-compliant jig and fixture plates requiring a PM-code press fit headless bushing with a 4.7-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machining technicians using an arbor press or hydraulic press to seat the bushing flush with the jig plate surface. Ensure the receiving bore is clean, dimensionally correct, and free of burrs before pressing. Do not use a hammer directly on the bushing face, as this can distort the bore geometry. Follow ANSI B94.33 jig bushing standards where applicable for fixture design and installation procedures.
