Boneham P206FH Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P206FH is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in machining and fabrication operations. Built from hardened steel with a Rockwell hardness of 60 to 65 HRC, this bushing provides consistent bore alignment and extended wear resistance under repeated drilling cycles. The inside diameter is 0.173 inches (wire size No. 17) with a tolerance of +0.0001 to +0.0004 inches, ensuring tight positional accuracy. The overall bushing length is 3/8 inches with a 5/16-inch body outside diameter. Machinists and toolmakers install this type of bushing directly into a jig plate without a locking collar or head flange.

The P206FH is suited for use in drill jigs and fixture plates in production machining environments, both in job shops and manufacturing facilities. Its headless, press fit design allows the bushing to sit flush with the jig plate surface, making it appropriate for close-tolerance drilling applications where a flanged bushing would interfere with the workpiece or adjacent features. The ANSI-standard construction ensures compatibility with industry-standard jig and fixture tooling practices.

Key Features

• Press fit installation method — no collar or retaining hardware required
• Headless design sits flush with jig plate surface for low-profile tool guidance
• Hardened steel construction at 60 to 65 HRC for wear resistance and long service life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Meets ANSI standards for drill bushing dimensions and fitment
• Non-renewable (fixed) bushing — intended for permanent press fit installation

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jig plates and fixture tooling requiring a 5/16-inch OD bore and 0.173-inch (No. 17 wire) inside diameter.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press — never drive with a hammer, as off-axis force can damage the bushing bore or the jig plate. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed to be removed and reused. Verify bore alignment with the fixture design before pressing the bushing to final depth.
