Boneham P166DV Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P166DV is a press fit headless drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. The P industry code designates a standard headless press fit design, with a 0.125 inch inside diameter, a 0.25 inch body outside diameter, and a 0.375 inch overall length. The tight inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures consistent hole location and repeatable accuracy. Machinists and toolmakers install this bushing into drill jig plates and fixtures on production floors and job shops.

This bushing is suited for production drilling operations where precise hole location is required. Its headless design allows flush installation into jig plates without protruding above the plate surface, making it appropriate for applications where clearance above the workpiece is limited. ANSI standards compliance makes it a direct fit for tooling designed to standard bushing specifications. The P166DV is commonly used in metalworking, fabrication, and machining environments.

Key Features

• Press fit installation method for secure, interference-fit seating in jig plates
• Headless design allows flush mounting with no head above the jig plate surface
• Steel construction hardened to 60 to 65 HRC for extended wear resistance
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance
• Meets ANSI standards for interchangeability with standard drill jig tooling

Compatibility

Designed as an ANSI-standard press fit headless drill bushing compatible with drill jig plates and fixtures built to P-series bushing specifications.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press to achieve a proper interference fit in the jig plate bore. Verify the receiving bore diameter matches the bushing outside diameter tolerance before pressing. Do not drive the bushing with impact tools, as this can damage the bushing bore or distort the outer diameter. Secure all workpieces and de-energize any powered equipment before performing fixture maintenance or bushing replacement.
