Boneham SP00008937 Slip-fixed Drill Bushing 0.75 in

Product Description

The BONEHAM SP00008937 is a slip-fixed drill bushing classified under industry code SF. It is designed to guide drill bits and cutting tools with precision during machining and fabrication operations. The bushing features a body outside diameter of 0.75 inches and a length under head of 1.5 inches, making it suitable for standard jig plate applications. It is a renewable bushing, meaning it can be removed and replaced without disturbing the liner bushing already installed in the jig. Machinists, toolmakers, and production technicians install this type of bushing in drill jigs to maintain accurate hole placement across repeated operations.

This slip-fixed bushing is used in drilling jig setups across general metalworking, manufacturing, and tool-and-die applications. The SF configuration allows the bushing to be locked in place during a drilling operation and then removed when the operation is complete. It is commonly found in both short-run and high-volume production environments where interchangeable tooling guidance is required. The inside diameter designation is letter N, which corresponds to a standard drill letter size for proper tool clearance.

Key Features

• Renewable slip-fixed design allows removal and replacement without disturbing the liner bushing
• Body outside diameter of 0.75 inches for standard liner bushing compatibility
• Length under head of 1.5 inches provides adequate guiding length for drilling operations
• Head outside diameter of approximately 1.047 inches with a head height of 0.25 inches
• Industry code SF classification for interchangeable tooling jig systems
• Inside diameter designation letter N for standard drill bit clearance

Compatibility

Designed as a renewable slip-fixed replacement bushing for standard SF-type drill jig liner bushings used in general metalworking and production machining applications.

Installation Notes

Installation is performed by toolmakers or machinists working with drill jig setups. The bushing is inserted into a compatible liner bushing already pressed into the jig plate and is secured by rotating it to the locked position. Ensure the jig is properly fixtured and the workpiece is secured before beginning any drilling operation. Remove the bushing before changing tooling operations or when switching to a different drill size.
