Hertel SZ20007C Abrasive Bur Cone Double Cut 1/8 in

Product Description

The HERTEL SZ20007C is a solid carbide abrasive bur with a cone-with-point-end head shape, designed for precision grinding, deburring, and material removal in metalworking and fabrication applications. Built to SM-41 industry specifications, this bur features a double cut tooth style that delivers efficient stock removal while maintaining control on contoured surfaces. The 1/8-inch shank diameter fits standard rotary tools and die grinders, and the 3/8-inch length of cut provides enough working surface for detail work in tight areas. The uncoated solid carbide head resists wear and holds edge geometry through repeated use on ferrous and non-ferrous metals.

This bur is suited for machinists, toolroom technicians, and fabricators who need precise material removal on castings, weldments, ports, and mold cavities. The cone-with-point-end geometry with a 12-degree included angle allows access to narrow grooves, chamfers, and interior contours where flat or ball-end tooling cannot reach. It is well-suited for die grinding operations on steel, aluminum, and cast iron in both shop and field settings.

Key Features

• SM-41 industry specification for standardized fitment and performance expectations
• Cone with point end head shape with 12-degree included angle for narrow-access grinding
• Double cut tooth style for fast stock removal with reduced chatter
• 1/8-inch cutting diameter and 1/8-inch shank diameter for compatibility with standard die grinder collets
• Solid carbide construction for extended tool life on hard materials
• Uncoated head for use across a broad range of metals without coating-compatibility concerns

Compatibility

Designed as an OEM-style replacement bur meeting SM-41 industry specifications, compatible with standard rotary die grinders and flex-shaft tools accepting a 1/8-inch shank collet.

Installation Notes

Installation of this bur is performed by machinists or fabricators using a die grinder or rotary tool with a matching 1/8-inch collet. Ensure the tool is fully powered down and unplugged before inserting or removing the bur. Tighten the collet nut securely before operation and inspect the shank for runout or damage prior to use. Always wear appropriate eye protection and follow shop safety protocols when operating rotary abrasive tooling.
