Boneham P265GK Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P265GK is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to Industry Code P standards, this headless bushing installs directly into a hardened or unhardened jig plate without a retaining screw or head flange. The bore measures 0.209 inches (wire size 4) with a tight inside diameter tolerance of plus 0.0001 to plus 0.0004 inches, ensuring accurate hole location across repeated operations. The body outside diameter is 13/32 inches and the overall length is 5/16 inches. Hardness runs 60 to 65 HRC, providing long service life under continuous drilling, reaming, or boring cycles.

This bushing suits production drilling and inspection fixture work in metalworking shops, tool rooms, and manufacturing environments. It is appropriate wherever a flush, low-profile guide bushing is required and no head protrusion is acceptable. Machinists, tool and die makers, and fixture builders are the typical installers. The ANSI-conforming dimensions make it a direct fit in standardized jig plate bore patterns that call for a P-series press fit headless bushing at this ID and OD combination.

Key Features

• Press fit installation — no retaining screw or head required
• Headless profile eliminates head interference in close-clearance fixture layouts
• 60 to 65 HRC hardness for extended wear life under repetitive tool contact
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance
• ANSI-conforming dimensions for compatibility with standard jig plate layouts
• Steel construction suited to general-purpose production drilling applications

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard jig plates and fixtures requiring a P-series press fit headless bushing with a 0.209-inch bore and 13/32-inch outside diameter per ANSI specifications.

Installation Notes

Installation is typically performed by a machinist or tool and die maker using an arbor press or hydraulic press to seat the bushing flush into a prepared jig plate bore. The receiving bore in the plate must be held to the mating tolerance specified for P-series press fit bushings to achieve proper interference. Do not drive the bushing with a hammer directly on the bore face, as this can distort the inside diameter. Always verify bore alignment and cleanliness before pressing to avoid galling the bushing OD or the plate bore.
