Hertel SZ0019B Abrasive Bur Ball 3/8 in Solid Carbide

Product Description

The HERTEL SZ0019B is a solid carbide abrasive bur with a ball head profile, designed for material removal, deburring, shaping, and finishing in metal fabrication and maintenance applications. The bur features a 3/8-inch cutting diameter and a 1/4-inch shank diameter, making it compatible with standard die grinders and rotary tools. The single-cut tooth style removes material efficiently while reducing clogging, and the uncoated solid carbide head delivers consistent hardness and heat resistance across a range of workpiece materials. Machinists, pipefitters, welders, and general maintenance technicians are the primary users of this type of bur.

The SZ0019B ball-profile bur is suited for contour grinding, weld blending, cavity work, and deburring in tight or curved surfaces where flat or cylindrical tools cannot reach. The ball shape allows access to concave surfaces, inside radii, and port-matching work on ferrous and non-ferrous metals. It is packaged as a single unit, appropriate for bench stock or field service kits. Typical use cases include metal fabrication shops, maintenance and repair operations, and trade work involving pipe, structural steel, or cast components.

Key Features

• Ball head profile for contouring, cavity finishing, and curved surface deburring
• 3/8-inch cutting diameter suited for moderate material removal on curved surfaces
• 1/4-inch shank diameter fits standard die grinders and rotary tool collets
• Single-cut tooth style for efficient chip evacuation and reduced heat buildup
• Solid carbide construction provides hardness and wear resistance on ferrous and non-ferrous metals
• Uncoated head finish for direct application without coating interference on workpiece surfaces

Compatibility

Designed as an OEM-style replacement carbide bur conforming to industry specification SD-3, compatible with die grinders and rotary tools accepting a 1/4-inch shank collet.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or rotary tool with a matching 1/4-inch collet. Secure the shank fully into the collet and tighten to the tool manufacturer's specified torque before operating. Always wear appropriate eye protection and ensure the workpiece is properly secured before engaging the bur. Do not exceed the maximum RPM rating of the tool or the bur.
