Hertel SZ0001O Abrasive Bur Oval 1/8 Inch Shank SE-41

Product Description

The HERTEL SZ0001O is a solid carbide abrasive bur with an oval head profile, designed for precision material removal in metalworking, deburring, and surface finishing applications. The head is uncoated solid carbide, delivering consistent cutting performance across ferrous and non-ferrous metals, hardened steels, and hard alloys. The single-cut tooth style produces smooth finishes and is well-suited for contouring and light stock removal. With a 1/8 inch shank diameter and 7/32 inch length of cut, this bur fits standard die grinders, rotary tools, and flex-shaft machines. It meets the SE-41 industry specification, making it a straightforward replacement or addition to a professional tooling setup.

This bur is used in general machining, toolroom work, maintenance and repair operations, and fabrication environments where controlled material removal is required. The oval head geometry allows access to contoured surfaces, recesses, and irregular profiles. It is appropriate for both bench-mounted and handheld rotary tool applications across industrial and trade settings. Machinists, tool and die technicians, and maintenance professionals are the primary installers and users of this type of bur.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or compatible rotary tool with a properly sized collet. Ensure the tool is fully powered down and the collet is secure before inserting the shank. Do not exceed the rated RPM of the tool or the bur. Inspect the bur for cracks or chips before each use and replace if any damage is visible.
