Boneham SFT486LR Slip-fixed Drill Bushing 17/32 in Id

Product Description

The BONEHAM SFT486LR is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers consistent bore alignment and long service life under repeated use. The inside diameter measures 17/32 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate tool guidance. The body outside diameter is 0.75 inches and the length under the head is 0.375 inches. It features a head type design with a 1-inch head outside diameter and a head height of 0.25 inches. Machinists, toolmakers, and fixture builders install this part in production and prototype jig setups.

This bushing is used in drill jig fixtures across metalworking and fabrication environments, both in job shops and production facilities. It is suited for applications requiring repeatable hole location accuracy, such as drilling, reaming, or counterboring operations. The renewable bushing design allows it to be swapped out without replacing the entire jig plate, making it practical for high-cycle tooling setups. Lock screw compatibility with the LS-TW-2 screw keeps the bushing secured in the liner during operation.

Key Features

• Slip-fixed installation method for easy removal and replacement during tool changes
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance in high-cycle applications
• Renewable bushing design allows replacement without disturbing the jig plate
• Compatible with LS-TW-2 lock screw for secure retention in liner bushings
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Compatible with LS-TW-2 lock screws. Designed as an OEM-style slip-fixed renewable drill bushing for use with standard SF-series liner bushings conforming to ANSI specifications.

Installation Notes

Installation is performed by toolmakers or machinists during jig and fixture assembly or maintenance. The bushing slips into a compatible liner bushing already pressed into the jig plate and is secured with an LS-TW-2 lock screw. Ensure the jig plate and liner bushing bore are clean and free of chips or burrs before seating the bushing. Follow ANSI jig bushing standards and shop safety procedures when assembling or servicing tooling fixtures.
