Hertel SZ2020TB Abrasive Bur Cylinder Radius SC-1L6

Product Description

The HERTEL SZ2020TB is a solid carbide abrasive bur with a cylinder-with-radius-end head geometry, designed for material removal, deburring, and surface finishing in metalworking and fabrication applications. The bur features a single-cut tooth style, a 1/4-inch cutting diameter, and a 1/4-inch shank diameter, making it compatible with standard die grinders and rotary tools. The uncoated solid carbide construction delivers hardness and wear resistance suitable for use on ferrous and non-ferrous metals. With a 6-inch overall length and a 1/2-inch length of cut, it reaches into recessed cavities and confined work areas that shorter burs cannot access.

This bur is suited for die grinding, weld blending, port matching, mold finishing, and similar close-tolerance material removal tasks in industrial, automotive, and toolroom environments. The SC-1L6 industry specification identifies the head shape and shank configuration, which is a recognized standard designation used when sourcing replacements or specifying burs for production grinding setups. Machinists, tool-and-die makers, and fabricators are the primary users of this style of bur.

Key Features

• Cylinder with radius end head shape provides smooth blending cuts and reduces corner chatter
• Single-cut tooth style removes material efficiently with reduced clogging on most metals
• Solid carbide head construction for durability and consistent cut quality
• 1/4-inch shank fits standard die grinder and rotary tool collets
• 6-inch overall length with 1/2-inch length of cut for reach into recessed areas
• Uncoated finish — no coating to chip or delaminate under high-heat grinding conditions

Compatibility

Designed as a standard replacement or production bur for die grinders and rotary tools accepting a 1/4-inch shank collet, conforming to SC-1L6 industry specification for cylinder-with-radius-end carbide burs.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder or compatible rotary tool with a 1/4-inch collet. Ensure the tool is powered off and unplugged before inserting or removing the bur. Tighten the collet nut to the tool manufacturer's specified setting using the appropriate collet wrenches — do not overtighten. Inspect the bur shank for runout or damage before use, and operate within the RPM rating of the host tool.
