Boneham SP00002746 Slip-fixed Drill Bushing 49/64 in Id

Product Description

The BONEHAM SP00002746 is a slip-fixed drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations in jig and fixture applications. Built to industry code SF, it features a 49/64-inch inside diameter and a 1-inch body outside diameter, with a 1-1/2-inch length under the head that provides solid tool guidance depth. This renewable bushing is installed into a liner bushing and can be replaced without disturbing the fixture, making it well suited for production environments where tooling wears and must be swapped efficiently. Machinists and toolmakers in manufacturing and metalworking shops install this type of component as part of precision drill jig assemblies.

This slip-fixed bushing is used in drill jig setups where the bushing must remain stationary during the cutting operation. The slip-fixed design allows the bushing to be installed and locked in position inside a liner, preventing rotation under cutting load. It is appropriate for production runs requiring consistent hole location across multiple workpieces. The renewable construction means the bushing can be swapped out for a different inside diameter or replaced after wear without rebuilding the entire fixture.

Key Features

• Industry code SF slip-fixed design locks bushing in place during cutting operations
• 49/64-inch inside diameter for precise tool guidance
• 1-inch body outside diameter fits standard liner bushings sized accordingly
• 1-1/2-inch length under head provides extended tool guidance
• 1-27/64-inch head outside diameter with 3/8-inch head height for positive seating
• Renewable bushing construction allows replacement without fixture disassembly

Compatibility

Designed as an OEM-style replacement for slip-fixed renewable drill bushings used in standard drill jig liner applications where a 1-inch body outside diameter liner bushing is installed.

Installation Notes

Installation is performed by toolmakers or machinists as part of drill jig assembly or maintenance. The liner bushing must be properly seated in the jig plate before installing this slip-fixed bushing. Ensure the locking mechanism engages fully to prevent bushing rotation during drilling. Always confirm inside diameter clearance matches the cutting tool shank diameter before use.
