Hertel SZ0003TW Abrasive Bur Tree Radius Solid Carbide

Product Description

The HERTEL SZ0003TW is a solid carbide abrasive bur with a tree with radius end head shape, designed for material removal, deburring, and shaping in metalworking and fabrication applications. Built to industry specification SF-53, this single-cut bur features a 3/16-inch cutting diameter and a 1/8-inch shank diameter, making it compatible with standard die grinders, rotary tools, and flex-shaft machines. The uncoated solid carbide construction delivers consistent cutting performance on ferrous and non-ferrous metals, hard plastics, and composites. Machinists, tool-and-die workers, and fabricators use this bur for contouring, slotting, and finishing in tight or curved workpiece geometries.

This bur is suited for precision material removal tasks in industrial and job-shop environments. The tree with radius end profile allows access to concave surfaces, curved channels, and radius blends that flat or cylindrical profiles cannot reach. With a 1/2-inch length of cut, it provides adequate reach for most standard die grinder applications. It is typically used by machinists, maintenance technicians, and fabricators working on steel, aluminum, cast iron, and similar materials.

Key Features

• Industry specification SF-53 tree with radius end head shape for curved and concave surface work
• Solid carbide construction for durability and consistent cutting performance
• Single-cut tooth style produces smooth finishes with efficient chip clearance
• 3/16-inch cutting diameter suited for detail work and tight geometries
• 1/8-inch shank fits standard die grinders and rotary tool collets
• Uncoated head for straightforward compatibility across common workpiece materials

Compatibility

Designed as an OEM-style replacement bur for use with standard die grinders, rotary tools, and flex-shaft machines accepting a 1/8-inch shank collet.

Installation Notes

Installation is performed by machinists or fabricators familiar with rotary tool operation. Ensure the die grinder or rotary tool is fully powered off and the collet is released before inserting or removing the bur. Secure the 1/8-inch shank firmly in the collet to the manufacturer-specified engagement depth before operation. Always wear appropriate eye protection and follow applicable shop safety standards when operating abrasive burs at rated speeds.
