Hertel SZ2002TR Abrasive Bur SF-3NF Tree Radius 3/8 in

Product Description

The HERTEL SZ2002TR is a solid carbide abrasive bur with a tree-with-radius-end head geometry, conforming to industry specification SF-3NF. It features an Aluma Cut tooth style, which is engineered for fast material removal in aluminum, soft metals, and non-ferrous materials while resisting chip loading. The cutting head measures 3/8 inch in diameter with a 3/4 inch length of cut, and the bur mounts on a 1/4 inch diameter shank. The uncoated solid carbide construction provides rigidity and durability under continuous rotary filing and blending operations.

This bur is suited for deburring, contouring, and blending operations on aluminum, brass, copper, plastics, and other non-ferrous or soft workpiece materials. The tree-with-radius end profile makes it well matched to profiling concave surfaces, blending weld seams, and working in areas that require a rounded cutting tip. Machinists, tool and die makers, and maintenance technicians commonly use this style of bur in die grinders and rotary tools for precision material removal in production and repair settings.

Key Features

• SF-3NF industry specification tree-with-radius-end head geometry for profiling concave and curved surfaces
• Aluma Cut tooth style engineered for efficient chip clearance in aluminum and soft non-ferrous metals
• Solid carbide head construction for rigidity and long service life under rotary filing loads
• 3/8 inch cutting diameter with 3/4 inch length of cut for targeted material removal
• 1/4 inch shank diameter compatible with standard die grinder and rotary tool collets
• Uncoated finish maintains consistent cutting geometry straight from the manufacturer

Compatibility

Designed as a standard SF-3NF style abrasive bur for use in die grinders and rotary tools accepting a 1/4 inch collet. Specific machine compatibility is determined by the 1/4 inch shank diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or compatible rotary tool with a 1/4 inch collet. Ensure the collet is fully tightened and the tool is disconnected from power before changing burs. Always operate within the maximum RPM rating of the die grinder and wear appropriate PPE, including eye protection and gloves, when using abrasive burs on metallic workpieces.
