Boneham SF206EF Slip-fixed Drill Bushing 0.1405 in Id

Product Description

The BONEHAM SF206EF is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards, this bushing features a 0.1405 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, a 5/16 inch body outside diameter, and a 3/8 inch length under head. Constructed from steel and hardened to 60 to 65 HRC, it delivers long service life in high-cycle drilling operations. The headed design and renewable construction allow it to be replaced without disturbing the jig plate, making it a practical choice for production tooling environments.

This bushing is suited for use in drill jigs, fixture plates, and precision tooling setups across manufacturing, machining, and metalworking applications. It fits wire size number 28 drill applications. The slip-fixed style allows the bushing to be installed and locked in place using a compatible lock screw, providing stable, repeatable tool guidance during drilling operations. It is compatible with the LS-1 lock screw and is appropriate for both short-run and production-volume work where consistent hole location is required.

Key Features

Compatibility

Compatible with LS-1 lock screws. Designed as an ANSI-standard slip-fixed drill bushing for use in standard liner bushings and drill jig plates accepting a 5/16 inch body outside diameter.

Installation Notes

Installation is typically performed by machinists or tooling technicians during jig assembly or bushing replacement. Ensure the liner bushing or jig plate bore is clean and free of burrs before seating the bushing. Use the appropriate LS-1 lock screw to secure the bushing in position before beginning drilling operations. Always verify tool clearance and bushing alignment before applying cutting force.
