Hertel SZ20008C Abrasive Bur Cone Double Cut 1/8 in Shank

Product Description

The HERTEL SZ20008C is a solid carbide abrasive bur with a cone-with-point-end head geometry, designed for precision material removal in tight or contoured areas. Built to SM-42 industry specification, this bur features a double-cut tooth style that delivers fast stock removal while producing a smoother finish than single-cut alternatives. The 1/8-inch shank fits standard die grinders and rotary tools commonly used in fabrication, maintenance, and tool-and-die work. Solid carbide construction provides the hardness and heat resistance needed for demanding deburring, porting, and surface preparation tasks on ferrous and non-ferrous metals.

This bur is suited for use in metal fabrication shops, maintenance and repair operations, and industrial manufacturing environments. The cone-with-point geometry makes it effective for working inside holes, chamfering edges, and accessing recessed surfaces. With a 7/16-inch length of cut and a 14-degree included angle, it is particularly useful where a tapered, pointed profile is required for precise material engagement. Machinists, tool-and-die makers, and maintenance technicians are the primary installers and users of this type of tooling.

Key Features

• SM-42 industry specification for standardized tooling compatibility
• Cone with point end head shape for tapered and recessed surface access
• Double-cut tooth style for efficient stock removal and improved surface finish
• Solid carbide head material for extended tool life in hard materials
• Uncoated head allows direct inspection of cutting edge condition
• 1/8-inch shank diameter fits standard die grinder collets

Compatibility

Designed as an OEM-style replacement or direct-use carbide bur for die grinders and rotary tools accepting a 1/8-inch shank collet, conforming to SM-42 industry specification.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or rotary tool with a compatible 1/8-inch collet. Ensure the tool is powered off and unplugged before inserting or removing the bur. Secure the shank fully in the collet to the recommended grip depth before operation. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools.
