Hertel SZ20012C Abrasive Bur Cone 1/4 Inch Shank Solid Carbide

Product Description

The HERTEL SZ20012C is a solid carbide abrasive bur with a cone and point end head geometry, designed for precision material removal, deburring, and surface finishing in metalworking and fabrication applications. Built to SM-1 industry specification, this bur features a single-cut tooth style and a 1/4-inch cutting diameter with a 1/4-inch shank. The uncoated solid carbide head delivers consistent performance on ferrous and non-ferrous metals, castings, and hard materials. It is sized for use in standard die grinders and rotary tools commonly used by machinists, tool-and-die workers, and maintenance technicians.

This bur is suited for use in industrial maintenance, metal fabrication shops, and precision machining environments. The cone with point end head shape allows access to confined areas, chamfering, countersinking, and working inside angled cavities. With a 1/2-inch length of cut and a 22-degree included angle, it is well-matched for detailed deburring work on drilled holes, weld cleanup, and die finishing tasks. It is typically installed in a collet-style die grinder or rotary handpiece and is intended for professional trade use.

Key Features

• SM-1 industry specification ensures compatibility with standard bur sizing conventions
• Cone with point end geometry for access to tight angles and confined cavities
• Solid carbide head construction for extended tool life on hard materials
• Single-cut tooth style produces smoother finishes with less chatter
• 1/4-inch shank fits standard die grinder collets and rotary tool chucks
• Uncoated head for direct material contact without coating interference

Compatibility

Designed for use with standard 1/4-inch collet die grinders and rotary tools commonly used in metalworking and fabrication applications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder or rotary handpiece with a 1/4-inch collet. Ensure the tool is fully powered off and depressurized before inserting or removing the bur from the collet. Tighten the collet securely to the tool manufacturer's specification to prevent slippage during operation. Always use appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools.
