Boneham SFT164DJ Slip-fixed Drill Bushing 7/64 in Id

Product Description

The BONEHAM SFT164DJ is a slip-fixed drill bushing used to guide cutting tools with precision in jig and fixture applications. It features a 7/64 inch inside diameter and a 1/4 inch body outside diameter, with a 1/4 inch length under the head. Manufactured from steel hardened to 60 to 65 HRC, this bushing maintains tight bore tolerances of +0.0001 to +0.0004 inches for repeatable hole location accuracy. It is designed with a head and is renewable, making it suitable for high-volume production environments where bushings require periodic replacement without retooling the fixture plate.

This bushing fits slip-fixed installations in drill jigs and machining fixtures across metalworking, toolmaking, and manufacturing operations. It is compatible with the LS-TW-2 lock screw, which secures the bushing in the liner during use. The SF industry code identifies it as a standard slip-fixed type, accepted across toolroom and production environments. Machinists, tool and die makers, and production technicians install this type of bushing in lined jig plates where the bushing must be removed and replaced between operations.

Key Features

• 7/64 inch inside diameter with +0.0001 to +0.0004 inch tolerance for precise tool guidance
• 1/4 inch body outside diameter and 1/4 inch length under head
• Steel construction hardened to 60 to 65 HRC for wear resistance
• Renewable design allows bushing replacement without disturbing the liner
• 7/16 inch head outside diameter with 1/4 inch head height
• Compatible with LS-TW-2 lock screw for positive retention in lined plates
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed for use with LS-TW-2 compatible lock screws. Fits standard lined jig plates accepting SF-type slip-fixed bushings per ANSI specifications. Confirm liner inside diameter matches 1/4 inch body outside diameter before installation.

Installation Notes

Slip-fixed bushings are installed and removed by hand or with a bushing press — never drive them in with a hammer, as this can damage the bore or the liner. The liner must be clean and free of chips before seating the bushing. Engage the LS-TW-2 lock screw to secure the bushing during the drilling operation. Always verify bore alignment with the fixture design before committing to production runs.
