Hertel SZ0004TW Abrasive Bur Tree Radius Single Cut Carbide

Product Description

The HERTEL SZ0004TW is a solid carbide abrasive bur with a tree-with-radius-end head profile, conforming to industry specification SF-51. It features a single-cut tooth style that produces a coarser chip load, making it well suited for aggressive material removal on metals, plastics, and composite surfaces. The cutting head measures 1/4 inch in diameter with a 1/2 inch length of cut, mounted on a 1/8 inch diameter shank. The uncoated solid carbide construction delivers consistent hardness and wear resistance across the cutting surface. This bur is a single-piece unit intended for use in pneumatic or electric die grinders and rotary tools used by machinists, fabricators, and tool-and-die professionals.

The SZ0004TW is appropriate for deburring, porting, shaping, and material removal operations in metalworking and fabrication environments. The SF-51 tree-with-radius geometry is commonly applied when contouring curved or recessed surfaces, cleaning weld joints, and smoothing internal profiles in castings or machined components. Its 1/8 inch shank fits standard collet sizes found on most die grinders and rotary tools used in production and maintenance settings.

Installation Notes

Installation of this bur is performed by machinists or fabricators using a die grinder or rotary tool. Ensure the tool is fully powered off and air supply is disconnected before changing burs. Insert the 1/8 inch shank fully into the collet and tighten to the tool manufacturer's specified collet torque before operation. Always wear appropriate eye and hand protection when operating abrasive burs.
