Hertel SZ2056TB Abrasive Bur Tree Radius 3/8 in Solid Carbide

Product Description

The HERTEL SZ2056TB is a solid carbide abrasive bur in a tree with radius end geometry, conforming to industry specification SF-3 TN. It is designed for material removal, deburring, shaping, and finishing operations on metals, composites, and hard materials. The 3/8 inch cutting diameter and 3/4 inch length of cut make it suited for moderate-depth work in contoured or recessed surfaces. The single-cut tooth style produces a smoother finish with lower cutting pressure compared to double-cut configurations. The 1/4 inch shank fits standard die grinders and rotary tools. Machinists, tool-and-die workers, and fabricators are the primary users of this type of bur.

This bur is used in metalworking, fabrication, and maintenance applications where a tree-with-radius profile is needed to blend radii, shape cavities, or remove material in areas that flat or cylindrical burs cannot reach. The uncoated solid carbide head performs well on ferrous and non-ferrous metals, cast iron, hardened steel, and similar hard materials. It is sold individually and is appropriate for benchtop grinding stations, handheld die grinders, and CNC tool-change fixtures equipped with a 1/4 inch collet.

Key Features

• Tree with radius end geometry for blending radii and shaping contoured or recessed surfaces
• Single-cut tooth style for smoother finish and reduced chatter on hard materials
• Solid carbide head construction for durability and heat resistance in demanding applications
• 3/8 inch cutting diameter with 3/4 inch length of cut for moderate-depth material removal
• 1/4 inch shank diameter compatible with standard die grinder collets and rotary tool chucks
• Uncoated head suitable for direct use on ferrous metals, non-ferrous metals, and hard alloys

Compatibility

Designed for use in die grinders, rotary tools, and similar power tools fitted with a 1/4 inch collet or chuck. Conforms to industry specification SF-3 TN.

Installation Notes

Installation and use should be performed by machinists or fabricators familiar with rotary cutting tools and applicable shop safety practices. Secure the 1/4 inch shank fully into the collet and verify the set screw or collet nut is tightened before operation. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured before applying cutting pressure. Do not exceed the rated RPM of the tool or bur, and inspect the carbide head for cracks or chips before each use.
