Boneham P205FX Press Fit Headless Drill Bushing

Product Description

The BONEHAM P205FX is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards, it features a 0.1935-inch inside diameter (Wire size No. 10) and a 5/16-inch outside diameter. The hardness rating of 60 to 65 HRC provides long service life under repeated drilling cycles. Machinist and tooling professionals install this bushing by pressing it directly into a prepared hole in a drill jig plate, where it stays fixed without a locking collar. The headless profile sits flush with the jig surface for unobstructed tool travel.

This bushing is used in precision jig and fixture setups found in machine shops, production tooling environments, and general metalworking operations. The P industry code designates it as a standard press fit type per ANSI specifications. Its 5/16-inch overall bushing length makes it well suited for thin jig plates and applications where a low-profile guide is required. Toolmakers and machinists working with No. 10 wire-gauge drills or equivalent decimal tooling will find this a direct-fit solution for fixed-position bushing installations.

Key Features

• Press fit installation method — no locking collar or head flange required
• Headless design sits flush with jig plate surface
• Inside diameter of 0.1935 inches with a tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance
• Hardness of 60 to 65 HRC for extended wear resistance
• Steel construction meets ANSI standards for drill bushing geometry and dimensional accuracy
• Not renewable — intended as a permanent fixed bushing in the jig plate

Compatibility

Designed as an OEM-style fixed drill bushing compatible with standard ANSI press fit jig plate applications requiring a No. 10 wire-gauge inside diameter and a 5/16-inch outside diameter body.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press to seat the bushing into a precision-reamed hole in the jig plate. The receiving hole must be reamed to the appropriate tolerance to achieve the correct interference fit. Never drive the bushing with a hammer blow directly to the bore face, as this can distort the inside diameter. Once pressed in, the bushing is not intended to be removed and reused.
