Boneham SFT3612IF Slip-fixed Drill Bushing 19/64 in Id Steel

Product Description

The BONEHAM SFT3612IF is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Classified under industry code SF, this bushing features a 19/64 inch inside diameter and a 9/16 inch body outside diameter, with a 3/4 inch length under the head. Constructed from steel, it delivers the hardness and wear resistance required for repetitive production drilling on jigs and fixtures. The head-style design seats securely against the jig plate, and the bushing is renewable, allowing it to be replaced without replacing the liner. Lock screw compatibility is rated for the LS-TW-2 fastener.

This slip-fixed bushing is used in tooling and fixturing applications across manufacturing, machining, and fabrication environments. It is installed in drill jig liners where the bushing must be locked in place during the drilling operation but can be removed and swapped when worn. Typical users include toolmakers, machinists, and production technicians working with jig setups that require consistent hole location and guide accuracy across multiple workpieces.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit slip-fixed bushing for SF-series drill jig liner systems. Compatible with LS-TW-2 lock screws as specified by the manufacturer.

Installation Notes

Installation is performed by toolmakers or machinists during jig setup or bushing replacement. The slip-fixed bushing is inserted into the appropriate liner and locked in position using the compatible LS-TW-2 lock screw before beginning any drilling operation. Ensure the jig plate and liner are clean and free of chips or debris before seating the bushing. Always verify that machine power is off and the workpiece is secure before servicing jig components.
