Hertel SZ0028C Abrasive Carbide Bur Cylinder SA-1 1/4 Inch

Product Description

The HERTEL SZ0028C is a solid carbide abrasive bur with a cylinder flat-end head profile conforming to the SA-1 industry specification. It features a double-cut tooth style, which produces a faster cut rate and finer finish compared to single-cut geometry. The cutting head measures 0.25 inches in diameter with a 0.625-inch length of cut, mounted on a 0.25-inch diameter shank. The carbide head is left uncoated for direct metal contact. Machinists, tool-and-die workers, and fabricators use this bur for deburring, shaping, and material removal in ferrous and non-ferrous metals, plastics, and composites.

This bur is suited for use in die grinders and rotary tools accepting a 0.25-inch shank. Common applications include weld blending, port relief work, mold finishing, and deburring of drilled or cast holes in production and maintenance environments. The cylinder flat-end geometry allows work on both the side and end of the bur, making it effective for step cuts and flat-bottomed cavities. It is typically used in metalworking, tool shops, and industrial maintenance operations.

Installation Notes

Installation is performed by qualified machinists or fabricators using a standard die grinder or rotary tool with a matching 0.25-inch collet. Always power down and disconnect the tool from its power source before inserting or removing the bur. Inspect the shank for damage or runout before use, and confirm the collet is properly tightened to the tool manufacturer specification. Eye protection and appropriate personal protective equipment should be worn during operation.
