Boneham SFT3616ID Slip-fixed Drill Bushing 0.295 in Id Steel

Product Description

The BONEHAM SFT3616ID is a slip-fixed drill bushing used to guide cutting tools with precision during drilling, reaming, or boring operations. Classified under industry code SF, this headed bushing features a 0.295 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate and repeatable tool guidance. The body measures 0.5625 inches in outside diameter with a 1 inch length under the head. Constructed from steel, it is designed for durability under repeated use in production jig and fixture applications. A 7/8 inch head outside diameter and 1/4 inch head height keep the bushing seated and stable during operation. This part is installed and serviced by toolmakers, machinists, and fixture maintenance technicians.

The SFT3616ID is suited for use in drill jigs and production fixtures where the bushing must be removed and replaced without disturbing the jig plate. The slip-fixed design allows the bushing to be locked in place during operation using a compatible lock screw, then released for bushing changes during tooling transitions. This makes it practical for multi-operation fixtures in manufacturing and machine shop environments where tool size changes between operations are required. The bushing is renewable, supporting long fixture service life without jig plate rework.

Installation Notes

Installation is performed by qualified toolmakers or machinists working on jig and fixture assemblies. Ensure the jig plate counterbore and liner bushing dimensions match the body OD and length specifications before installation. The bushing should be seated fully and locked using the appropriate LS-TW-2 lock screw before initiating any drilling operation. Do not force the bushing into an undersized or damaged liner bushing, as this can compromise tool guidance accuracy and bushing integrity.
