Boneham CB00001330 Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM CB00001330 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Classified under industry code SF, this bushing features an inside diameter of 0.1065 inches (wire size No. 36) and a body outside diameter of 0.3125 inches (5/16 inches). Constructed from steel hardened to 60 to 65 HRC, it delivers the wear resistance required in production jig-and-fixture applications. The head-type design and LS-1 compatible lock screw make it a renewable component, allowing replacement without disturbing the jig plate. Length under head is 0.5 inches, and the inside diameter tolerance is held to plus 0.0001 to plus 0.0004 inches.

This bushing is used in drill jigs and fixture plates across metalworking, machining, and light manufacturing environments. The slip-fixed configuration allows the bushing to be installed and locked in place with a mating lock screw, making it suitable for applications where the bushing must remain stationary during the full drilling cycle. It is appropriate for tool-room, production, and maintenance machining operations where repeatable hole location is critical. Machinists, tool and die makers, and fixture builders are the primary installers.

Key Features

• Slip-fixed (SF) industry classification for stationary, locked-in-place drilling guidance
• Inside diameter of 0.1065 inches held to a tight tolerance of plus 0.0001 to plus 0.0004 inches
• Steel construction hardened to 60 to 65 HRC for extended wear life in production use
• Renewable bushing design — replaceable without full jig plate rework
• LS-1 compatible lock screw interface for secure seating during the drilling cycle
• Head-type configuration with a head OD of 35/64 inches and head height of 1/4 inches

Compatibility

Designed for use with LS-1 series lock screws in standard ANSI drill jig bushing plates. Meets ANSI standards for slip-fixed renewable drill bushings.

Installation Notes

Installation is performed by machinists or tool and die makers during jig plate setup or bushing replacement. The jig plate must be free of chips and debris before seating the bushing to maintain positional accuracy. Secure the bushing using a compatible LS-1 lock screw; do not overtighten the lock screw beyond hand-snug plus a controlled quarter-turn without a specified torque reference for the screw size in use. Always verify bore alignment and bushing seating before returning the fixture to production service.
