Hertel SZ20035C Abrasive Bur Cone 1/2 Inch Solid Carbide

Product Description

The HERTEL SZ20035C is a solid carbide abrasive rotary bur with a cone-with-point-end head shape, designed for material removal, deburring, and surface finishing in demanding industrial and trade applications. Conforming to SK-5 industry specification, this bur features a 1/2-inch cutting diameter, a 1/4-inch length of cut, and a single-cut tooth style. The solid carbide construction delivers hardness and wear resistance suitable for ferrous and nonferrous metals, plastics, and composites. The uncoated head provides consistent cutting performance without coating buildup concerns. Machinists, tool-and-die technicians, pipefitters, and fabricators reach for this style of bur when removing flash, blending welds, or profiling tight internal cavities.

This bur is suited for use with pneumatic die grinders, flexible-shaft grinders, or electric rotary tools accepting a 1/4-inch collet or chuck. The cone-with-point-end geometry at a 90-degree included angle makes it well-matched for countersinking, chamfering, spot-facing, and deburring hole edges or angled surfaces. It is equally at home in metal fabrication shops, maintenance and repair operations, and field service environments where portable rotary tools are standard equipment. The 1/4-inch shank fits the most common die-grinder collet size used in industrial and trade settings.

Key Features

• SK-5 industry specification for standardized tool identification and application matching
• Cone with point end geometry at a 90-degree included angle for chamfering, countersinking, and cavity work
• Solid carbide head construction for superior hardness and extended service life compared to steel burs
• Single-cut tooth style produces smooth finishes and is effective on a wide range of base materials
• Uncoated head eliminates coating separation concerns and maintains consistent chip clearance
• 1/4-inch shank diameter fits standard die-grinder collets without adapters

Compatibility

Designed as a direct-fit replacement for SK-5 specification cone-with-point-end rotary burs used with 1/4-inch collet die grinders and rotary tool systems.

Installation Notes

Installation is performed by qualified machinists or trade technicians using a die grinder or rotary tool with a 1/4-inch collet. Ensure the tool is powered off and disconnected from the air supply or electrical source before inserting or removing the bur. Secure the shank fully in the collet and tighten to the tool manufacturer's specified torque before operation. Always wear appropriate eye protection and follow applicable ANSI safety standards for rotary cutting tool use.
