Boneham SP00008923 Slip-fixed Drill Bushing 0.5in

Product Description

The BONEHAM SP00008923 is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured to industry code SF, this bushing features a 0.5-inch body outside diameter and a 1.5-inch length under the head, making it suited for moderate-depth drilling operations. The renewable design allows the bushing to be replaced without disturbing the jig plate, reducing downtime in production environments. Machinists, tool-and-die makers, and maintenance technicians install this type of bushing when repeatable hole location and concentricity are critical to the operation.

This bushing is used in drill jigs, fixture plates, and tooling setups across general metalworking, fabrication, and manufacturing environments. The slip-fixed configuration allows the bushing to be locked in place during drilling while still being removable for bushing changes or tool swaps. It is appropriate for both light production runs and high-volume repetitive drilling where consistent hole placement is required. The K inside diameter designation further identifies the bore size for proper drill or reamer fit.

Key Features

• Slip-fixed installation method for secure seating with field-removable capability
• Body outside diameter of 0.5 inches for standard jig plate fit
• Length under head of 1.5 inches for moderate-depth drilling guidance
• Head outside diameter of 0.797 inches (51/64 inches) for positive shoulder seating
• Head height of 0.25 inches provides a low-profile flange
• Renewable bushing construction supports replacement without jig plate rework

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard SF-series slip-fixed drill bushing applications where a 0.5-inch body outside diameter and K bore designation are specified.

Installation Notes

Installation is typically performed by a machinist or tooling technician during jig assembly or bushing replacement. The jig plate bore must be clean and within tolerance before pressing or inserting the bushing. Secure the bushing fully to the head shoulder to ensure proper seating and prevent axial movement during drilling. Always verify bore size and bushing series against the existing jig plate specification before installation.
