Hertel SZ20007T Abrasive Bur Tree Single Cut Solid Carbide

Product Description

The HERTEL SZ20007T is a solid carbide abrasive bur with a tree-with-pointed-end head geometry and a single-cut tooth style. It carries an SG-51 industry specification and is designed for precision material removal, deburring, and contouring in metalworking and fabrication applications. The 1/4 inch cutting diameter and 1/2 inch length of cut make it well suited for working in confined areas, port work, and detail finishing. The uncoated solid carbide head delivers consistent cutting performance on ferrous and non-ferrous materials. The 1/8 inch shank fits standard die grinders and rotary tool collets used by machinists, toolmakers, and maintenance technicians.

This bur is used in metal fabrication shops, maintenance and repair operations, and general machining environments. The tree-with-pointed-end profile is commonly selected for weld blending, cavity work, and contour finishing where a tapered cutting tip is needed to reach tight radii or angled surfaces. It is appropriate for use on steel, cast iron, aluminum, and similar materials. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers and users of this bur type.

Key Features

Compatibility

Designed as an OEM-style replacement bur conforming to SG-51 industry specifications, compatible with die grinders and rotary tools accepting a 1/8 inch collet or shank.

Installation Notes

This bur is installed and used by machinists, fabricators, and maintenance technicians operating die grinders or rotary tools. Ensure the tool is fully powered down and the collet is fully released before inserting or removing the bur. Confirm the collet size matches the 1/8 inch shank before tightening. Always operate within the RPM rating of the host tool and use appropriate eye protection per shop safety standards.
