Boneham SP00008953 Slip-fixed Drill Bushing 0.377 in Id

Product Description

The BONEHAM SP00008953 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, it features an inside diameter of 0.377 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate and repeatable hole placement. The body outside diameter measures 0.75 inches and the length under the head is 0.375 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance required for production drilling operations. It is compatible with the LS-1 lock screw and meets ANSI standards. Machinists, toolmakers, and manufacturing technicians install this component in drill jigs.

This bushing is suited for use in metal fabrication, tooling, and machining environments where consistent hole location is critical. The slip-fixed design allows the bushing to be removed and replaced without disturbing the jig body, making it well-suited for operations that require tool changes between drilling and reaming. The renewable bushing feature extends the service life of the fixture by allowing the worn liner to be swapped out independently. It is a standard choice for production jig work across industrial manufacturing settings.

Key Features

• Inside diameter of 0.377 inches (Letter size V) with ANSI-specified tolerance of +0.0001 to +0.0005 inches
• Body outside diameter of 0.75 inches and length under head of 0.375 inches
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Slip-fixed (SF) installation method allows tool-change removal without jig disassembly
• Renewable bushing design enables liner replacement independent of the fixture body
• Compatible with LS-1 lock screw for secure seating during operation
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an ANSI SF-standard slip-fixed drill bushing compatible with LS-1 lock screws and suitable for use in standard drill jig liners accepting a 0.75 inch body outside diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolmaker with the workpiece fixture secured and all power to the machine tool removed before bushing insertion or removal. The slip-fixed design requires a mating liner already pressed into the jig body; ensure the liner bore is clean and free of chips before seating the bushing. Use the LS-1 compatible lock screw to lock the bushing in position during the drilling cycle and remove it before pulling the bushing for tool changes. Do not force the bushing into an undersized liner bore.
