Boneham SFT165DM Slip-fixed Drill Bushing 0.111 in Id Steel

Product Description

The BONEHAM SFT165DM is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and similar machining operations. Assigned industry code SF, this bushing features a 0.111 inch inside diameter and a 0.250 inch body outside diameter, making it suited for close-tolerance work where repeatable hole location is critical. Constructed from steel with a headed design, it is installed into a jig plate and secured with a compatible lock screw. The 5/16 inch length under head provides solid tool guidance depth in typical fixture applications. Machinists, toolmakers, and fixture builders are the primary installers.

This bushing is applied in drill jig fixtures used across general machining, metalworking, and production tooling environments. Its slip-fixed installation method means it can be removed and replaced without disturbing the liner bushing, making it a practical choice for fixtures that see tool changes or periodic bushing replacement. The renewable design supports ongoing production use where bushing wear is expected. Both job-shop and production-floor applications are common scenarios for this part type.

Key Features

• Slip-fixed installation method allows removal and replacement without disturbing the press-fit liner
• Steel construction provides durability and wear resistance in production drilling applications
• Headed design with 7/16 inch head outside diameter and 1/4 inch head height for positive seating against the jig plate
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance
• Compatible with LS-TW-2 lock screw for secure retention during operation
• Renewable bushing design supports extended fixture service life

Compatibility

Compatible with LS-TW-2 lock screws as specified by the manufacturer. Designed as an OEM-style slip-fixed drill bushing replacement for standard SF-style drill jig liner applications.

Installation Notes

Installation is typically performed by a machinist or toolmaker during jig assembly or bushing replacement. The bushing is inserted into a compatible liner bushing already pressed into the jig plate, then locked in place with the specified LS-TW-2 lock screw. Ensure the jig fixture is secured and the machine is powered down before servicing or replacing bushings. Do not force the bushing into a liner with a non-matching bore size, as this can damage the inside diameter tolerance and compromise tool guidance accuracy.
