Boneham CB00001230 Slip-fixed Drill Bushing 0.1935 in Id

Product Description

The BONEHAM CB00001230 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built from steel with a hardness rating of 60 to 65 HRC, this bushing delivers consistent bore alignment and resists wear over repeated use. It features a 0.1935 inch inside diameter, a 0.5000 inch body outside diameter, and a 1 inch length under head. The head-type design and LS-1 compatible lock screw keep the bushing securely seated during drilling operations. Licensed machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is suited for use in drill jigs where a renewable, slip-fixed bushing station is required. The slip-fixed style allows the bushing to be removed and replaced without disturbing the jig plate, making it appropriate for production environments where multiple operations or tool changes occur at a single station. It conforms to ANSI standards for drill bushing dimensions and tolerances, ensuring interchangeability within standard jig bushing systems. The renewable design extends the service life of the fixture by allowing worn bushings to be swapped out independently.

Key Features

• Slip-fixed bushing style (industry code SF) for tool-change and renewable-station applications
• 0.1935 inch inside diameter with a close tolerance of plus 0.0001 to plus 0.0004 inches for accurate tool guidance
• Steel construction hardened to 60 to 65 HRC for long service life in production drilling
• Head-type design with 51/64 inch head outside diameter and 1/4 inch head height for positive seating
• LS-1 compatible lock screw interface to secure the bushing in the liner
• Renewable bushing design allows replacement without removing the liner from the jig plate

Compatibility

Designed as a renewable slip-fixed drill bushing conforming to ANSI standards, compatible with LS-1 lock screws and standard jig bushing liners sized for a 1/2 inch body outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists working with drill jig fixtures. The bushing is inserted into a previously installed liner and secured with an LS-1 lock screw. Ensure the liner bore and mating surfaces are clean and free of chips before seating the bushing. Follow ANSI jig bushing standards and shop safety procedures when pressing or rotating bushings into position.
