Boneham SFT168DC Slip-fixed Drill Bushing 0.1015 in Id

Product Description

The BONEHAM SFT168DC is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code SF, this bushing features a 0.1015 inch inside diameter corresponding to a number 38 wire gauge drill size, with a body outside diameter of 0.2500 inches and a length under head of 0.5 inches. Constructed from steel, it delivers the hardness and wear resistance required for repetitive drilling operations on production floors and fabrication shops. The headed design keeps the bushing seated against the jig plate surface during use, and the renewable configuration allows replacement without scrapping the liner bushing assembly.

This bushing is used in drill jig setups across metalworking, tooling, and precision machining environments. It is installed into a liner bushing pressed into the jig body, then locked in place with a compatible lock screw. Typical applications include production drilling where consistent hole location is critical across multiple workpieces. The slip-fixed style allows the bushing to be rotated into a locked position, making it suitable for operations that require tool changes between stations without disturbing hole registration.

Key Features

• Slip-fixed (SF) installation method for tool-change flexibility without repositioning the jig
• 0.1015 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Steel construction for hardness and long service life in repetitive drilling applications
• Headed design with a 7/16 inch head outside diameter and 1/4 inch head height for positive seating against jig plates
• Renewable bushing design allows field replacement within an existing liner bushing
• Compatible with LS-TW-2 lock screw for secure retention during operation

Compatibility

Designed for use with LS-TW-2 compatible lock screws and standard liner bushings sized to accept a 1/4 inch body outside diameter slip-fixed bushing per industry SF specifications.

Installation Notes

Installation is typically performed by a toolmaker or machinist setting up a drill jig assembly. Ensure the liner bushing is fully seated and secured in the jig plate before inserting the slip-fixed bushing. Rotate the bushing to the locked position and secure with the appropriate LS-TW-2 lock screw before beginning drilling operations. Inspect the bushing bore and seating surfaces for wear periodically, and replace the bushing when inside diameter tolerance can no longer be maintained.
