Hertel SZ2021C Abrasive Bur Cylinder Radius Aluma Cut SC-3NF

Product Description

The HERTEL SZ2021C is a solid carbide abrasive bur with a cylinder and radius end head geometry, conforming to industry specification SC-3NF. It is designed for deburring, grinding, and stock removal on aluminum and non-ferrous metals. The Aluma Cut tooth style features a specialized flute pattern that evacuates chips efficiently, reducing loading and heat buildup during use. The 3/8 inch cutting diameter and 3/4 inch length of cut make it well-suited for moderate-scale material removal in confined areas. The 1/4 inch shank mounts in standard die grinders and rotary tools used by machinists, fabricators, and toolroom technicians.

This bur is intended for use in metalworking and fabrication environments where aluminum, soft metals, or non-ferrous alloys are being shaped, deburred, or finish-ground. It fits standard collet chucks on pneumatic and electric die grinders. Typical applications include weld cleanup, port matching, casting cleanup, and edge breaking on aluminum components. It is also used in maintenance and repair operations where precise material removal is required in tight or contoured areas.

Installation Notes

Installation and use should be performed by qualified machinists or fabricators familiar with rotary cutting tool safety. Ensure the die grinder is unpowered and depressurized before inserting or removing the bur from the collet. Inspect the shank and cutting head for cracks or damage before each use. Always operate within the RPM rating of the tool and wear appropriate eye and face protection.
