Boneham CB00001140 Slip-fixed Drill Bushing 15/64 in Id

Product Description

The BONEHAM CB00001140 is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling and reaming operations. Built from steel with a hardness rating of 60 to 65 HRC, this bushing provides lasting resistance to wear in high-cycle jig and fixture applications. The 15/64 inch inside diameter maintains a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location across repeated operations. The body outside diameter measures 0.5000 inches with a 1 inch length under the head. A headed design with a 51/64 inch head outside diameter and 1/4 inch head height locks the bushing securely in the jig plate. Installation uses the LS-1 compatible lock screw system. This bushing is renewable, making it suitable for production tooling where periodic replacement is expected.

This bushing is used in drill jigs and fixture plates in precision machining environments, including production manufacturing, tool and die shops, and maintenance repair operations. The slip-fixed installation method allows the bushing to be inserted and locked in position by a lock screw, providing stability during drilling while remaining field-replaceable. It is appropriate for both metalworking and general fabrication applications where repeatable hole accuracy is required. Machinists and tool builders are the primary installers in these environments.

Key Features

• Slip-fixed installation method with LS-1 compatible lock screw for secure seating in jig plates
• Steel construction hardened to 60 to 65 HRC for wear resistance in high-cycle drilling
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Headed design with 51/64 inch head OD and 1/4 inch head height for positive axial location
• Renewable bushing design supports production tooling with periodic replacement
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an ANSI-standard slip-fixed renewable drill bushing compatible with LS-1 lock screws and standard jig plate liners accepting a 1/2 inch body outside diameter.

Installation Notes

Installation is performed by machinists or tool builders during jig and fixture assembly or maintenance. The jig plate liner bore and lock screw thread must be inspected and cleaned before inserting the bushing. Ensure the lock screw is fully engaged before beginning any drilling operation to prevent rotation or axial movement under load. When replacing a worn bushing, confirm the replacement bushing matches the original inside diameter tolerance class to maintain hole location accuracy.
