Hertel SZ2003TR Abrasive Bur Tree Radius 1/2 in Solid Carbide

Product Description

The HERTEL SZ2003TR is a solid carbide abrasive bur with a tree-with-radius-end head geometry, designed for material removal, deburring, and contouring in metalworking and fabrication applications. It features an Aluma Cut tooth style, which is optimized for efficient chip evacuation and reduced loading when working aluminum and other non-ferrous materials. The cutting diameter is 1/2 inch with a 1 inch length of cut, and it runs on a 1/4 inch shank. The uncoated solid carbide construction delivers consistent edge integrity across repeated use. This bur is typically installed in pneumatic die grinders or rotary tools by machinists, tool and die workers, and fabricators.

The SZ2003TR is suited for deburring, blending, and shaping operations on aluminum, brass, copper, and other soft metals where the Aluma Cut geometry prevents chip packing. It fits standard 1/4 inch collet die grinders used in production shops, maintenance facilities, and fabrication environments. The tree-with-radius end profile is commonly used for contoured pocket work, port matching, and radius blending in confined areas where straight or cylindrical burs cannot reach effectively. It conforms to industry specification SF-5NF.

Key Features

• Aluma Cut tooth style optimized for non-ferrous metals — reduces chip loading and improves cut efficiency
• Solid carbide head construction for consistent geometry and extended tool life
• Tree with radius end profile suited for contoured pockets, port work, and radius blending
• 1/2 inch cutting diameter with 1 inch length of cut for moderate material removal
• 1/4 inch shank fits standard die grinder collets without adapters
• Uncoated finish — no coating delamination risk during aggressive passes
• Meets industry specification SF-5NF

Compatibility

Designed for use with standard 1/4 inch shank pneumatic or electric die grinders. Compatible with aluminum, brass, copper, and other non-ferrous workpiece materials per the Aluma Cut tooth specification.

Installation Notes

Installation is performed by machinists or fabricators using a standard collet-style die grinder. Ensure the grinder is fully powered off and the collet is released before inserting or removing the bur. Tighten the collet to the tool manufacturer's specified torque using the correct collet wrench — do not overtighten or use pliers on the shank. Always verify the grinder RPM rating meets or exceeds the bur's rated maximum speed before operation, and wear appropriate eye and face protection.
