Boneham P6422LU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P6422LU is a press fit headless drill bushing with a 35/64-inch inside diameter and a 1-inch outside diameter. It is manufactured from steel and features an overall length of 1-3/8 inches. This bushing is classified under industry code P and is installed by pressing directly into a jig plate or fixture body without the use of a head flange. Machinists and toolmakers use this type of bushing to guide drill bits, reamers, and other cutting tools with precision repeatability across production runs. The tight inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance.

The P6422LU is suited for use in drill jigs, fixture plates, and precision machining setups where a flush, headless installation is required. Its press fit installation method means the bushing seats securely in the fixture without additional hardware. This style is commonly used in manufacturing environments, machine shops, and toolroom applications where repetitive hole location accuracy is critical. It is not a renewable-type bushing and is intended as a permanent press-in installation.

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard jig and fixture plates requiring a 1-inch body outside diameter press fit bore.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a prepared bore. Power down all associated machinery and secure the fixture before pressing in the bushing. The receiving bore should be finish-reamed to the appropriate interference fit specification before installation. Once pressed in, this bushing is not designed for removal or replacement.
