Value Collection -22693-4 Inverted Cone Abrasive Bur SN-3

Product Description

The VALUE COLLECTION -22693-4 is a solid carbide inverted cone abrasive bur designed for precision material removal in metalworking, toolmaking, and die-grinding applications. Built to industry specification SN-3, this bur features a 1/2 inch cutting diameter and a 1/4 inch shank diameter. The uncoated solid carbide head provides consistent cutting performance across a range of ferrous and non-ferrous materials. The 16-degree included angle of the inverted cone profile makes it well suited for undercutting, deburring recessed areas, and finishing angled surfaces that straight-profile burs cannot reach effectively.

This bur is used in die grinding, mold finishing, weld cleanup, and precision deburring tasks across manufacturing, fabrication, and maintenance shops. It fits standard 1/4 inch collet die grinders and rotary tools commonly found in machine shops and maintenance environments. The inverted cone geometry is particularly useful where access is limited or where the work surface has undercut features requiring a tapered, angled cutting head.

Key Features

• Industry specification SN-3 inverted cone profile for undercutting and angled surface work
• Solid carbide head construction for durability and consistent cutting performance
• 1/2 inch cutting diameter with 16-degree included angle
• 1/4 inch shank fits standard die grinder and rotary tool collets
• Uncoated head for straightforward material compatibility across common workpiece materials

Compatibility

Designed for use with standard 1/4 inch collet die grinders and rotary tools. Conforms to industry specification SN-3 for inverted cone abrasive burs.

Installation Notes

Install the bur shank fully into the die grinder collet and tighten securely before operation. Always power down and disconnect the tool before changing burs. Wear appropriate eye protection and secure the workpiece before use. Follow the tool manufacturer guidelines for maximum RPM to avoid bur damage or breakage.
