Boneham AM00000996 Slip-fixed Drill Bushing 6.25mm Id

Product Description

The BONEHAM AM00000996 is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. It features a 6.25 mm inside diameter with a tight tolerance of +0.005 to +0.014 mm, a 12 mm body outside diameter, and a 25 mm length under the head. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance required for repeated tooling cycles in production jigs and fixtures. The counterbored head design allows secure, locked seating in a liner bushing. It is a renewable bushing, meaning it can be replaced without disturbing the fixture body.

This bushing is used in precision metalworking and machining applications where consistent hole location is critical across multiple parts. It seats into a fixed liner bushing installed in a drill jig or fixture plate and is held in place by rotation into a locked position. Typical environments include production machine shops, tool-and-die operations, and maintenance repair facilities. The SF and SFM industry code designation indicates compatibility with standard slip-fixed liner bushing systems conforming to ANSI specifications. Machinists, toolmakers, and fixture builders are the primary installers.

Key Features

• 6.25 mm inside diameter with +0.005 to +0.014 mm tolerance for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for long service life in high-cycle applications
• Renewable design allows in-place replacement without removing the liner bushing from the fixture
• Counterbored head provides positive locking engagement when rotated into a slip-fixed liner
• Conforms to ANSI standards for SF and SFM bushing interchangeability
• 12 mm body outside diameter and 22 mm head outside diameter for standard liner seating

Compatibility

Designed for use with standard ANSI slip-fixed liner bushings in SF and SFM configurations. Specific compatible fixture hardware or liner part numbers were not provided in the product data.

Installation Notes

Installation is performed by toolmakers or machinists as part of drill jig assembly or maintenance. Before replacing a bushing in an active fixture, ensure all cutting tools are retracted and the machine is powered down. The bushing is inserted into the liner and rotated to the locked position using the appropriate locking notch. Do not force or hammer the bushing into the liner, as this can damage the bore tolerance or the liner seat.
