Hertel SZ2004TR Abrasive Bur Tree Radius Aluma Cut

Product Description

The HERTEL SZ2004TR is a solid carbide abrasive bur with a tree-with-radius-end head geometry, designed for material removal, deburring, and shaping in metalworking and fabrication applications. It features an Aluma Cut tooth style, which is optimized for cutting aluminum and other non-ferrous metals with reduced clogging and smoother chip evacuation. The cutting head measures 5/8 inch in diameter with a 1-inch length of cut, and the bur mounts on a 1/4-inch shank for use in standard die grinders and rotary tools. The uncoated solid carbide construction delivers consistent cutting performance and dimensional stability under sustained use.

This bur is suited for use by machinists, fabricators, tool-and-die makers, and maintenance technicians working on aluminum, soft metals, plastics, and composites. Typical applications include port matching, weld blending, cavity work, and general contouring where a tree-with-radius profile is required. The Aluma Cut geometry makes it particularly effective in aerospace, automotive, and general metalworking shops handling non-ferrous stock. The 1/4-inch shank fits the vast majority of die grinders and flexible-shaft machines used in trade and production environments.

Key Features

• Aluma Cut tooth style reduces loading and improves chip flow on aluminum and non-ferrous metals
• Solid carbide head construction for rigidity and extended tool life
• Tree with radius end profile for contouring, cavity work, and blending operations
• 5/8-inch cutting diameter with 1-inch length of cut
• 1/4-inch shank diameter compatible with standard die grinders and rotary tools
• Uncoated head finish — no coating delamination risk during high-contact operations

Compatibility

Designed for use in standard 1/4-inch collet die grinders and rotary tools. Meets industry specification SF-6NF for tree-with-radius-end carbide bur geometry.

Installation Notes

Installation and removal should be performed with the die grinder powered off and air supply disconnected or power unplugged. Insert the 1/4-inch shank fully into the collet before tightening to the tool manufacturer's recommended torque. Wear appropriate eye and face protection during operation. Do not exceed the maximum RPM rating of the tool or the bur; consult the tool manufacturer's documentation for safe operating speeds.
