Hertel SZ0009TW Abrasive Bur Tree with Radius SF-1

Product Description

The HERTEL SZ0009TW is a solid carbide abrasive bur with a tree with radius end head shape, designed for material removal, deburring, and surface blending in metalworking and fabrication applications. Built to industry specification SF-1, this single cut bur features a 1/4 inch cutting diameter and a 5/8 inch length of cut. The uncoated solid carbide head delivers consistent cutting performance across a range of materials. It accepts a standard 1/4 inch shank, making it compatible with common die grinders and rotary tools used in production and maintenance environments. Machinists, tool and die workers, and fabrication technicians are the primary users.

This bur suits applications requiring controlled stock removal on ferrous metals, aluminum, and similar materials. The tree with radius end geometry is well suited for working in contoured recesses, blending radii, and finishing irregular profiles. Single cut tooth style produces smoother finishes and is preferred when operator control and surface quality matter. It fits standard rotary die grinder setups found in machine shops, maintenance facilities, and light fabrication environments.

Installation Notes

Installation is performed by machinists or fabrication technicians using a standard die grinder with a matching 1/4 inch collet. Ensure the tool is fully powered down and unplugged before inserting or removing the bur. Confirm the collet is properly tightened before operation and inspect the carbide head for chips or damage prior to each use. Always wear appropriate PPE including eye protection when operating rotary cutting tools.
