Boneham SF3216FF Slip-fixed Drill Bushing 0.1695in Id Steel

Product Description

The BONEHAM SF3216FF is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.1695 inches (Wire Size 18), a body outside diameter of 0.5000 inches, and a length under head of 1 inch. Constructed from steel, this bushing provides a durable, wear-resistant guide surface for repetitive drilling operations. The head outside diameter measures 51/64 inches with a head height of 1/4 inch. Inside diameter tolerance is held to plus 0.0001 to plus 0.0004 inches, ensuring consistent tool guidance across production runs.

This bushing is suited for use in drill jigs and fixtures where a removable, renewable guide is required. The slip-fixed style allows the bushing to be installed and locked in place using a compatible lock screw, making it appropriate for multi-operation setups where the bushing must remain stationary during the cut. It is used primarily in manufacturing, tool and die, and precision machining environments. The counterbored design accommodates flush or near-flush seating in a jig plate.

Installation Notes

Slip-fixed drill bushings are installed by machinists or toolmakers into hardened jig plates sized to accept the bushing body OD. The bushing is pressed or slipped into the liner bushing and locked with a compatible LS-1 lock screw to prevent rotation during the drilling operation. Ensure the mating liner bushing bore and the jig plate are clean and free of chips before installation. Do not force the bushing with impact tools that could damage the precision ground ID.
