Boneham SFT1612DK Slip-fixed Drill Bushing Steel

Product Description

The BONEHAM SFT1612DK is a slip-fixed drill bushing designed to guide cutting tools with precision during machining and drilling operations. Built to industry code SF, this headed bushing features an inside diameter of 0.11 inches (wire size 35), a body outside diameter of 0.25 inches, and a length under head of 0.75 inches. Constructed from steel, it delivers the hardness and wear resistance required for repeated use in jig and fixture applications. The renewable design allows the bushing to be replaced without disturbing the jig plate, supporting consistent hole location across production runs. Lock screw compatibility with the LS-TW-2 screw secures the bushing against rotation during use.

This bushing is suited for use in drill jigs and machining fixtures in manufacturing, toolroom, and production environments. Slip-fixed bushings are typically installed where a single operation is performed at each location and the bushing remains in place during the cut. The headed configuration provides a positive stop against the jig plate surface, maintaining consistent seating depth. Machinists, tool and die makers, and production drilling technicians are the primary installers of this component.

Key Features

• Slip-fixed SF industry code design holds bushing in position during drilling operations
• Inside diameter of 0.11 inches with a tight tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance
• Steel construction provides hardness and durability for high-cycle jig applications
• Renewable bushing design allows replacement without jig plate rework
• Headed style with 0.4375 inch head outside diameter and 0.25 inch head height seats flush against the jig plate
• LS-TW-2 compatible lock screw prevents rotation under load

Compatibility

Compatible with LS-TW-2 lock screws as specified by the manufacturer. Designed as an OEM-style slip-fixed renewable drill bushing for use in standard SF-pattern drill jig plates and fixtures.

Installation Notes

Drill bushing installation is typically performed by machinists or tool and die makers using standard press-fit or slip-fit jig plate procedures. Before servicing or replacing a bushing, ensure all power to the machine is off and the workpiece is fully secured. Use the appropriate lock screw driver or hex key for the LS-TW-2 screw to secure the bushing after seating. Do not over-tighten the lock screw, as this can distort the bushing bore and affect tool guidance accuracy.
