Boneham SP00008961 Drill Bushing 23/64 in Id 3/4 in Od

Product Description

The BONEHAM SP00008961 is a press fit headless drill bushing designed to guide cutting tools accurately during drilling operations. Manufactured from hardened steel with a surface hardness of 60 to 65 HRC, it maintains precise bore alignment under repeated use. The bushing features a 23/64-inch inside diameter with a tight inside diameter tolerance of +0.0001 to +0.0005 inches, ensuring consistent hole location and drill guidance. The 3/4-inch body outside diameter and 5/8-inch overall length make it a compact, reliable component for jig and fixture applications. It installs by press fitting directly into a prepared jig plate without a head or flange. Machinists, tool and die makers, and fixture builders are the primary installers.

This bushing is suited for production drilling fixtures, jig plates, and tooling assemblies in machine shops, manufacturing facilities, and maintenance environments. The headless press fit design keeps the bushing flush with the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece positioning or tool clearance. It conforms to ANSI standards for drill bushing geometry and is not designed to be renewed or replaced in service once pressed in.

Key Features

• Press fit installation - no retaining ring or locking mechanism required
• Hardened steel construction at 60 to 65 HRC for wear resistance and long service life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance
• Headless design sits flush with jig plate surface to clear workpieces
• ANSI-compliant geometry for standard fixture and tooling compatibility
• Non-renewable design - intended as a permanent press fit installation

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in production drilling jigs, fixture plates, and tooling setups requiring a 23/64-inch inside diameter and 3/4-inch outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to seat the bushing into a prepared bore in the jig plate. The receiving bore must be machined to the correct press fit tolerance to avoid damage to the bushing or plate. Do not drive the bushing in with a hammer directly on the bore face. Once pressed in, this bushing is not intended to be removed or reused.
