Hertel SZ20020T Abrasive Bur Tree 1/2 in Solid Carbide

Product Description

The HERTEL SZ20020T is a solid carbide abrasive bur with a tree-with-pointed-end head shape, built for aggressive material removal in tight or contoured areas. It features a 1/2 inch cutting diameter, a 3/4 inch length of cut, and a double cut tooth pattern that clears chips efficiently while delivering a moderately smooth finish. The 1/4 inch shank is compatible with standard die grinders and rotary tools used across machining, fabrication, and tool-and-die work. The uncoated solid carbide construction provides hardness and wear resistance suited to ferrous and non-ferrous materials. This bur is sold individually and conforms to SG-13 industry specifications.

This bur is used in metalworking, weld preparation, deburring, porting, and surface blending applications. The tree-with-pointed-end profile is particularly well suited for working inside cavities, along contoured surfaces, and in areas where flat or ball-end profiles lack access. It is commonly used by machinists, tool grinders, maintenance technicians, and fabricators working in job shops, manufacturing facilities, and maintenance environments. The double cut pattern makes it effective on steel, cast iron, aluminum, and similar materials.

Installation Notes

Install in a die grinder or rotary tool with a properly sized 1/4 inch collet; ensure the collet is tightened securely before operation.

Inspect the bur for chipping or cracks before each use and replace if damage is present.
