Hertel SZ20012T Abrasive Bur Tree Double Cut 1/4 in

Product Description

The HERTEL SZ20012T is a solid carbide abrasive bur with a tree with pointed end head shape, designed for precision material removal in tight or contoured workpieces. It features a double cut tooth style that delivers fast stock removal while leaving a smoother finish compared to single cut. The cutting head measures 1/4 inch in diameter with a 1/2 inch length of cut, and the bur mounts on a 1/8 inch shank. This tool meets industry specification SG-51 and is uncoated, making it well suited for use on ferrous and non-ferrous metals, hardened steels, and hard plastics. Machinists, tool-and-die makers, and fabricators rely on this bur for die finishing, weld blending, and deburring operations.

This bur is used in rotary die grinders, flexible-shaft machines, and high-speed handpieces across metalworking, fabrication, and maintenance shops. The pointed tree profile allows access into angled cavities, mold pockets, and contoured surfaces where flat or cylindrical burs cannot reach. It is appropriate for both bench-top and in-field grinding tasks. The 1/8 inch shank fits the most common collet sizes used in pneumatic and electric die grinders found in production and repair environments.

Installation Notes

This bur is installed by a machinist or maintenance technician into a die grinder or rotary handpiece equipped with a matching 1/8 inch collet. Always power down and disconnect the tool from its air supply or electrical source before inserting or removing the bur. Secure the shank fully within the collet to the depth recommended by the tool manufacturer before operating. Inspect the bur for chips or cracks before each use and replace if damaged to avoid breakage during operation.
