Boneham CB00001377 Press Fit Headed Drill Bushing

Product Description

The BONEHAM CB00001377 is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 0.043-inch inside diameter, a 5/32-inch body outside diameter, and a 3/8-inch length under head. Machined from steel, this bushing is pressed permanently into a jig plate and requires no locking mechanism. The flanged head seats flush against the jig plate surface to control tool depth and alignment. It is installed by machinists and toolmakers working in precision drilling, reaming, and boring operations.

This bushing is suited for use in drill jigs where a permanent, non-renewable guide is specified. The 0.043-inch bore corresponds to wire gauge size 57. The headed design provides a positive stop at the jig plate face, making it appropriate for applications requiring consistent hole location across repeated production runs. It is commonly used in metal fabrication shops, machine shops, and manufacturing environments where tight positional tolerance is required.

Key Features

• Type H headed press fit design — installs permanently without a locking collar
• 0.043-inch inside diameter (wire gauge 57) with tolerance of +0.0001 to +0.0004 inches
• 5/32-inch body outside diameter, 1/4-inch head outside diameter, 3/32-inch head height
• 3/8-inch length under head for standard jig plate thicknesses
• Steel construction for wear resistance and dimensional stability
• Non-renewable (fixed) bushing — intended for permanent installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a Type H press fit headed bushing with a 0.043-inch bore and 5/32-inch body diameter per industry standard classifications.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press to seat the bushing flush into a precision-bored jig plate hole. Power down all nearby machinery before handling or pressing components. Do not drive the bushing with a hammer, as this can damage the bore geometry or distort the head seating surface. Verify jig plate bore diameter matches the bushing body outside diameter tolerance before pressing.
