Hertel SZ20033C Abrasive Carbide Bur Cone SK-1 1/4 Inch

Product Description

The HERTEL SZ20033C is a solid carbide abrasive rotary bur in the SK-1 cone-with-point-end geometry, designed for precise material removal in metalworking and fabrication applications. The 1/4-inch shank fits standard die grinders and rotary tool chucks. With a 1/4-inch cutting diameter, a 1/8-inch length of cut, and a 90-degree included angle, this bur delivers controlled stock removal in tight contours, V-grooves, and countersink deburring. The single-cut tooth style produces a smoother finish compared to double-cut configurations and generates less chatter on harder materials. The uncoated solid carbide head provides consistent performance across steel, cast iron, and other ferrous and non-ferrous metals.

This bur is suited for deburring, chamfering, and contouring tasks in manufacturing, maintenance, and tool-and-die work. The SK-1 cone-with-point profile makes it particularly effective for cleaning weld seams, sharpening internal angles, and opening up tight-radius features. It is typically used by machinists, fabricators, and maintenance technicians operating die grinders or flexible-shaft machines in both shop and field environments.

Key Features

• SK-1 cone-with-point-end geometry for precise V-groove and angular work
• Solid carbide head for long tool life on ferrous and non-ferrous metals
• Single-cut tooth style for smoother finish and reduced chatter
• 1/4-inch shank diameter compatible with standard die grinder collets
• 90-degree included angle suited for chamfering and countersink work
• Uncoated head for straightforward resharpening if required

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 fabricators using standard die grinder equipment. Ensure the tool is fully de-energized and the collet is completely loosened before inserting or removing the bur shank. Verify that the shank is fully seated and the collet nut is secured before operating. Always operate within the RPM rating of the die grinder and use appropriate eye and face protection when running rotary burs.
