Hertel SZ0001TW Abrasive Bur Tree Radius 1/8 Inch

Product Description

The HERTEL SZ0001TW is a solid carbide abrasive bur with a tree-with-radius-end head geometry, manufactured to SF-41 industry specification. It is designed for controlled material removal on metals, composites, and hardened materials in die grinding, deburring, porting, and surface-blending applications. The 1/8-inch shank fits standard die grinders and rotary tools. The single-cut tooth style produces a smoother finish with lower vibration compared to double-cut configurations, making it well suited for finishing passes and contour work. The uncoated solid carbide construction provides hardness and wear resistance across a range of workpiece materials.

This bur is used in metalworking, tool-and-die, automotive, and fabrication shops where precise material removal in contoured or radius areas is required. The tree-with-radius geometry allows access to curved internal profiles, blended transitions, and pocket corners that straight or cylindrical burs cannot reach efficiently. It is installed and operated by machinists, toolmakers, and skilled fabricators using pneumatic or electric die grinders.

Key Features

• SF-41 industry specification tree-with-radius-end head geometry for contour and radius work
• Single-cut tooth style for smoother finish and reduced chatter
• Solid carbide head construction for hardness and extended wear life
• Uncoated head — no coating buildup risk on ferrous or non-ferrous materials
• 1/8-inch shank diameter fits standard die grinder collets
• 1/4-inch length of cut for controlled engagement depth

Compatibility

Designed as a standard SF-41 specification replacement bur compatible with 1/8-inch collet die grinders and rotary tools used in metalworking and fabrication applications.

Installation Notes

Installation is performed by machinists or fabricators using a die grinder with a matching 1/8-inch collet. Ensure the grinder is fully powered down and depressurized before inserting or changing the bur. Secure the shank fully within the collet to the recommended engagement depth per the tool manufacturer guidelines. Operate within the RPM rating of the grinder and inspect the bur for chipping or wear before each use.
