Hertel SZ2002O Abrasive Bur Oval 1/2 in Aluma Cut Carbide

Product Description

The HERTEL SZ2002O is a solid carbide abrasive bur in an oval head shape, conforming to industry specification SE-5NF. It is designed for deburring, shaping, and material removal on aluminum and non-ferrous metals. The Aluma Cut tooth style features a geometry optimized to reduce loading and chatter when cutting softer materials, producing a cleaner finish with less clogging. The 1/2-inch cutting diameter and 7/8-inch length of cut provide sufficient contact area for contouring work in die-making, fabrication, and maintenance applications. It accepts a standard 1/4-inch shank and is compatible with most pneumatic and electric die grinders used in trade shops.

This bur is suited for metalworking professionals in fabrication, tool and die, aerospace maintenance, and industrial repair environments. It performs best on aluminum, brass, copper, and other non-ferrous materials where the Aluma Cut geometry prevents chip packing. Typical use cases include port matching, weld blending, cavity work, and edge preparation. The uncoated solid carbide construction maintains cutting edge integrity across repeated passes without requiring a surface treatment.

Installation Notes

Installation and use of rotary carbide burs should be performed by qualified machinists or trade professionals familiar with rotary cutting tool safety. Ensure the die grinder is fully powered off and disconnected from its air or electrical supply before inserting or removing the bur from the collet. Verify the collet size matches the 1/4-inch shank before tightening, and confirm the tool RPM rating does not exceed the rated speed of the bur. Eye protection and appropriate PPE are required during operation.
