Hertel SZ20005C Abrasive Bur Cone Single Cut 1/8 Inch

Product Description

The HERTEL SZ20005C is a solid carbide abrasive bur with a cone-with-point-end head geometry, designed for precision material removal in metalworking, die finishing, and deburring applications. Built to SM-43 industry specification, this single-cut bur features a 1/8-inch cutting diameter, a 5/8-inch length of cut, and a 1/8-inch shank diameter that fits standard rotary tool chucks and die grinders. The uncoated solid carbide head provides consistent cutting performance on ferrous and non-ferrous metals, as well as hard plastics and composites. The 7-degree included angle of the cone tip allows access to tight internal profiles and chamfered edges. Weighing just 0.0088 pounds, this bur is suited for repetitive use in production or maintenance environments.

This bur is commonly used by machinists, tool-and-die makers, maintenance technicians, and fabricators working on mold cavities, weld seams, port matching, and general surface preparation. The cone-with-point-end geometry is well suited for reaching into countersinks, angled grooves, and contoured surfaces where flat or cylindrical burs cannot reach effectively. It is appropriate for use in both manual die grinder setups and machine-mounted spindle applications.

Key Features

• SM-43 industry specification for standardized fit and performance
• Cone with point end head shape for access to tight angles and contoured profiles
• Single-cut tooth style for smooth material removal with reduced chatter
• Solid carbide construction for durability on hard materials
• 1/8-inch shank diameter fits standard die grinder and rotary tool collets
• Uncoated head for broad material compatibility without coating interference

Compatibility

Designed to fit standard 1/8-inch collets on die grinders and rotary tools conforming to SM-43 industry specification for abrasive bur shanks.

Installation Notes

Installation is performed by machinists or maintenance technicians using a compatible die grinder or rotary tool with a 1/8-inch collet. Ensure the tool is fully powered off and the collet is securely tightened before operation. Do not exceed the maximum RPM rating of the host tool. Eye protection and appropriate hand protection should be worn during use per standard shop safety practices.
