Hertel SZ0008TW Abrasive Bur Tree Radius 1/4 in Double Cut

Product Description

The HERTEL SZ0008TW is a solid carbide abrasive bur with a tree with radius end head shape, designed for material removal, deburring, shaping, and surface finishing on ferrous and non-ferrous metals, hardened steels, and other hard materials. Built to industry specification SF-51, this double cut bur features a 1/4 inch cutting diameter and a 1/2 inch length of cut. The 1/8 inch shank fits standard die grinders and rotary tools commonly used in fabrication, toolroom, and maintenance environments. The uncoated solid carbide construction delivers consistent cutting performance across a wide range of workpiece materials.

This bur is suited for use in metalworking, aerospace fabrication, automotive, die and mold work, and general maintenance applications. It handles internal and external contour work, weld cleanup, port blending, and cavity finishing. The tree with radius end profile makes it especially effective for accessing curved or irregular internal surfaces. It is sold and packaged as a single unit and is appropriate for use by machinists, toolmakers, and skilled trade professionals working with die grinders or flexible-shaft rotary tools.
