Boneham PT248GQ Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT248GQ is a headless press fit drill bushing designed to guide drill bits and cutting tools with precision in metalworking and machining applications. Manufactured from steel, this bushing features an inside diameter of 0.221 inches, a body outside diameter of 3/8 inch, and an overall length of 1/2 inch. The press fit installation method holds the bushing securely in a drill jig plate without the need for fasteners or locking collars. The headless design allows the bushing to sit flush with the jig surface, making it well-suited for close-tolerance drilling operations where a protruding flange would interfere with workpiece clearance.

This bushing carries the industry code P and is intended for use in drill jig fixtures across a range of production and toolroom settings. It is a non-renewable (fixed) bushing, meaning it is pressed directly into the jig plate and is not designed for field removal and replacement without specialized tooling. Machinists, tool and die makers, and jig builders working in metalworking shops are the primary installers of this component.

Key Features

• Press fit installation — no fasteners or locking collar required
• Headless design sits flush with jig plate surface for unobstructed workpiece access
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures consistent tool guidance
• Steel construction for durability under repeated drilling cycles
• Bushing industry code P for standard jig fixture compatibility
• Compact 1/2 inch overall length suitable for thin jig plate applications

Compatibility

Designed as a standard P-code press fit headless drill bushing for use in drill jig fixtures requiring a 3/8 inch body outside diameter and 0.221 inch inside diameter tool guide.

Installation Notes

Installation is performed by tool and die makers or machinists using an arbor press or hydraulic press to seat the bushing flush into a precisely reamed jig plate bore. The jig plate bore must be held to the appropriate interference fit tolerance to retain the bushing under cutting forces. Do not strike the bushing directly with a hammer, as this can damage the bore geometry or distort the inside diameter. Remove all chips and debris from the jig plate bore before pressing in the bushing.
