Boneham SFT3612JB Slip-fixed Drill Bushing 11/32 in Id

Product Description

The BONEHAM SFT3612JB is a slip-fixed drill bushing designed to guide cutting tools accurately through jig plates in precision machining and metalworking applications. Built to industry code SF, this headed bushing features an 11/32-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 wear resistance and dimensional stability required for repeated production use. The renewable design allows the bushing to be removed and replaced without disturbing the jig plate, extending overall tooling life. Lock screw compatibility with the LS-TW-2 screw secures the bushing in position during drilling operations.

This bushing is suited for use in drill jigs and fixtures across manufacturing, fabrication, and toolroom environments. It is appropriate for applications requiring a removable, renewable guide bushing where consistent hole location accuracy is critical across multiple workpieces. The headed configuration seats flush against the jig plate surface, providing a positive stop and preventing axial migration during tool engagement. Machinists, tool and die makers, and production drilling technicians typically specify this type of bushing for moderate-to-high volume jig work.

Key Features

• Slip-fixed installation method allows tool-free removal for bushing changes between operations
• 11/32-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction provides durability and resistance to wear under repeated drilling cycles
• Renewable bushing design extends jig plate service life by isolating wear to the replaceable component
• Compatible with LS-TW-2 lock screw for positive retention during operation
• Headed style with 7/8-inch head outside diameter and 1/4-inch head height for positive seating

Compatibility

Compatible with LS-TW-2 lock screws. Designed as an OEM-style renewable slip-fixed drill bushing for use in standard SF-series drill jig applications.

Installation Notes

Installation is performed by machinists or toolroom technicians working with drill jigs and fixtures. Ensure the liner bushing or jig plate bore is clean and free of chips or debris before seating the bushing. Secure with an LS-TW-2 compatible lock screw to prevent rotation or axial movement during drilling. Always verify inside diameter clearance with the intended drill or reamer shank before committing the bushing to production use.
