Boneham SF205DE Slip-fixed Drill Bushing 0.104 in Id Steel

Product Description

The BONEHAM SF205DE is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.104 inches (wire size No. 37) and a body outside diameter of 0.3125 inches (5/16 inch), with a length under the head of 5/16 inch. Constructed from steel and hardened to 60 to 65 HRC, this bushing maintains tight bore tolerances of +0.0001 to +0.0004 inch, making it well-suited for production drilling and repetitive-location work. It is compatible with the LS-1 lock screw and is renewable, allowing replacement without disturbing the liner bushing.

This SF-series slip-fixed bushing is used in drill jig plates across light manufacturing, tool and die, and precision machining environments. The slip-fixed design allows the bushing to be rotated and locked into position using an LS-1 lock screw, making it practical for operations where tool changes occur between setups. The head outside diameter measures 35/64 inch with a head height of 1/4 inch. It conforms to ANSI standards and is appropriate for shops requiring consistent, repeatable hole placement in metalworking and fabrication operations.

Compatibility

Compatible with LS-1 lock screws. Designed as an ANSI-standard SF-series slip-fixed renewable drill bushing for use with standard jig liner bushings in drill fixture applications.

Installation Notes

Installation is performed by machinists or tool and die technicians during jig plate setup or bushing replacement. Ensure the mating liner bushing bore is clean and free of chips before inserting the SF205DE. Secure the bushing in the correct rotational position using an LS-1 lock screw before beginning drilling operations. Always verify spindle alignment and tool clearance prior to running the drill press or machining center.
