Boneham P1312CK Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P1312CK is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision during machining operations. Manufactured from steel, this bushing carries industry code P and features an inside diameter of 0.082 inches (wire gauge number 45) with an inside diameter tolerance of +0.0001 to +0.0004 inches. The headless, counterbored body design allows it to seat flush within a jig plate, keeping the tool path consistent across repeated operations. Machinists, tool-and-die makers, and jig builders working in fabrication or production environments rely on parts like this to maintain hole location accuracy.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups where a permanent, non-renewable guide bushing is required. The press fit installation method locks the bushing directly into the jig body without a locking collar or liner bushing. Applications include production drilling, reaming guide setups, and other precision metalworking operations where repeatable hole placement is critical. The headless profile is preferred when flush mounting is required or when clearance above the jig plate surface is limited.

Key Features

• Inside diameter of 0.082 inches (wire gauge number 45) with tight tolerance of +0.0001 to +0.0004 inches
• Body outside diameter of 13/64 inches for press fit into standard jig plate bores
• Overall bushing length of 3/4 inches provides solid tool guidance depth
• Headless design enables flush or sub-flush installation in jig plates
• Counterbored body accommodates standard press fit jig configurations
• Steel construction for durability in production drilling environments

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig setups requiring a P-series press fit headless bushing with a 0.082-inch inside diameter and 13/64-inch outside diameter.

Installation Notes

Press fit bushings are typically installed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush within the jig plate bore. Power down any associated machinery before installing or removing bushings from active fixtures. Ensure the receiving bore is clean, dimensionally correct, and free of burrs before pressing to avoid damaging the bushing or misaligning the tool path. Do not drive bushings with a hammer strike directly on the face, as this can deform the bore.
