Boneham PT365IZ Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT365IZ is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision during machining and metalworking operations. Manufactured from steel, this bushing features a 0.339-inch inside diameter and a 9/16-inch body outside diameter, with an overall length of 5/16 inch. It installs without a head, sitting flush within the jig plate for a clean, low-profile fit. The inside diameter tolerance of +0.0001 to +0.0005 inch ensures consistent, repeatable hole location. Machinists, tool and die makers, and production shop technicians install these bushings into drill jigs to maintain accurate hole positioning across production runs.

This bushing is suited for use in drill jig applications where press fit retention is required and a headless profile is preferred to avoid interference with workpieces or fixtures. It carries Industry Code P, which defines the outside diameter and length per standard drill bushing classifications. The non-renewable design makes it a permanent fixture once pressed into the jig body. Typical applications include production drilling, reaming guidance, and fixture tooling in both job shop and manufacturing environments.

Key Features

• Press fit installation method for secure, permanent retention in jig plates
• Headless design provides flush, low-profile seating within the fixture
• Steel construction for durability under repeated drilling cycles
• Inside diameter tolerance of +0.0001 to +0.0005 inch for consistent hole location accuracy
• Industry Code P classification for standardized outside diameter and length dimensions
• Non-renewable bushing - intended as a permanent jig component

Compatibility

Designed as a standard Industry Code P press fit headless drill bushing for use in drill jigs and fixture plates requiring a permanent, headless bushing with a 0.339-inch inside diameter and 9/16-inch outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press to drive the bushing into a pre-machined jig plate bore. Ensure the receiving bore is machined to the appropriate interference fit tolerance before pressing to avoid bushing distortion or bore damage. Once pressed in, this bushing is not intended for removal or replacement. Always verify inside diameter clearance with the intended drill or reamer before installation.
