Boneham SFT245GB Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM SFT245GB is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, this headed bushing accepts a No. 8 wire size bore with an inside diameter of 0.199 inches and holds a tight inside diameter tolerance of +0.0001 to +0.0004 inches. The body outside diameter measures 0.375 inches with a length under head of 0.3125 inches. Constructed from steel and hardened to 60 to 65 HRC, the SFT245GB is a renewable bushing intended for installation and removal without disturbing the liner bushing. It is compatible with LS-TW-2 lock screws and conforms to ANSI standards.

This bushing is used in precision drilling, reaming, and boring jigs across general machining, toolmaking, and manufacturing environments. The slip-fixed design allows the bushing to be locked in place during operation and removed for tool changes or replacement without special equipment. Typical installers include toolmakers, machinists, and fixture builders working in job shops, production facilities, or maintenance departments where repeatable hole location accuracy is required.

Key Features

• Slip-fixed SF industry code design for use with liner bushings

• Conforms to ANSI standards for drill bushing dimensions

Compatibility

Compatible with LS-TW-2 lock screws. Designed as an OEM-style renewable slip-fixed drill bushing for use with standard SF-series liner bushings in jig and fixture tooling applications.

Installation Notes

Installation is typically performed by a toolmaker or machinist. Ensure the mating liner bushing bore and the jig plate are clean and free of debris before seating the bushing. Secure with a compatible LS-TW-2 lock screw to prevent rotation during drilling operations. Do not press or hammer the bushing into a fixed location — the slip-fixed design requires a liner bushing for proper fitment.
