Value Collection -22693-2 Inverted Cone Abrasive Bur SN-1

Product Description

The VALUE COLLECTION -22693-2 is a solid carbide inverted cone abrasive bur designed for precision material removal in tight or angled workspaces. Conforming to the SN-1 industry specification, this bur features a 1/4 inch cutting diameter and a 5/16 inch length of cut, making it well suited for deburring, contouring, and shaping operations in metal, composites, and similar hard materials. The uncoated solid carbide head delivers consistent cutting performance and resists wear under repeated use. It is installed on a 1/4 inch shank and fits standard rotary tools and die grinders used across machining, fabrication, and maintenance trades.

This inverted cone bur is used in applications where a controlled, angled cutting profile is required, such as chamfering, spot facing, and back-deburring in confined areas. The 10-degree included angle of the inverted cone head geometry allows access to recessed surfaces and undercuts that straight or ball-end burs cannot reach. It is appropriate for benchtop die grinder work, CNC tool post applications, and hand-held rotary tool use in metal fabrication shops, maintenance facilities, and production environments.

Key Features

• Conforms to SN-1 industry specification for inverted cone rotary burs
• Solid carbide head construction for extended tool life in hard materials
• Uncoated finish suitable for general-purpose cutting and deburring
• 1/4 inch cutting diameter with 5/16 inch length of cut
• 10-degree included angle for access to recessed and undercut surfaces
• 1/4 inch shank diameter fits standard die grinders and rotary tool chucks

Compatibility

Designed as an OEM-style replacement or direct-use rotary bur for die grinders and rotary tools accepting a 1/4 inch shank collet.

Installation Notes

Installation is performed by machinists, fabricators, and maintenance technicians using standard die grinders or rotary tools. Before inserting or removing the bur, ensure the tool is fully powered down and unplugged or the air supply is disconnected. Secure the shank firmly in the collet to the tool manufacturer-specified tightening procedure to prevent slippage during operation. Always wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools.
