Boneham SP00008900 Slip-fixed Drill Bushing 19/64 in Id

Product Description

The BONEHAM SP00008900 is a slip-fixed drill bushing used to guide cutting tools accurately through jig plates during precision drilling, reaming, or boring operations. It features a 19/64 inch inside diameter, a 3/4 inch body outside diameter, and a 1-1/2 inch length under head. The renewable design allows the bushing to be removed and replaced without disturbing the jig liner, making it a practical choice for production environments where tooling changes are frequent. Machinists and tool-and-die tradespeople install this type of bushing in drill jigs and fixture assemblies to maintain consistent hole location across multiple workpieces.

This bushing is suited for use in metalworking and manufacturing jig applications where repeatable hole positioning is required. The slip-fixed configuration uses a locking notch that prevents rotation during drilling while still allowing quick removal when the tool setup changes. It is appropriate for both short-run and high-volume production fixtures in shops working with ferrous and non-ferrous materials. The 1/4 inch head height and 1-3/64 inch head outside diameter provide positive seating against the jig plate surface.

Key Features

• Slip-fixed installation method for secure, rotation-resistant seating with quick-change capability
• 19/64 inch inside diameter for precise cutting tool guidance
• 3/4 inch body outside diameter fits standard jig liner bores
• 1-1/2 inch length under head accommodates moderate jig plate thicknesses
• Renewable bushing design supports in-place replacement without jig rework
• Industry code SF for straightforward cross-referencing with standard bushing catalogs

Compatibility

Designed as an OEM-style replacement slip-fixed drill bushing for use in standard drill jig assemblies that accept a 3/4 inch body outside diameter liner bore and require a 19/64 inch tool guide.

Installation Notes

Installation is performed by qualified machinists or toolmakers familiar with drill jig assembly. Ensure the mating jig liner bore is clean and free of burrs before pressing or seating the bushing. Use the locking notch and a compatible lock screw to secure the bushing against rotation during cutting operations. Remove the bushing only after cutting tools are fully retracted and the workpiece is secure.
