Hertel SZ0003B Abrasive Bur Ball 5/32 in Solid Carbide

Product Description

The HERTEL SZ0003B is a solid carbide abrasive bur with a ball-shaped head, designed for material removal, deburring, and surface finishing in metalworking and fabrication applications. The ball profile allows access to contoured surfaces, cavities, and radiused profiles where flat or cylindrical tools cannot reach. With a cutting diameter of 5/32 inches and a 1/8-inch shank, this bur fits standard die grinders, rotary tools, and flex-shaft machines. The single-cut tooth style produces smoother finishes with less chatter and is well suited for ferrous and non-ferrous metals. The uncoated solid carbide head offers consistent cutting performance and resists wear under continuous use.

This bur is used in maintenance, repair, and fabrication shops for tasks such as port matching, weld cleanup, mold finishing, and precision deburring of cast or machined parts. The compact ball head and standard 1/8-inch shank make it compatible with a wide range of handheld rotary and pneumatic die grinder setups. It is typically selected by machinists, tool and die makers, and fabricators working on detailed or hard-to-reach geometry in metal components.

Key Features

• Ball head profile for contouring, cavity work, and radiused surface finishing
• Single-cut tooth style for smoother finish and reduced chatter on metalwork
• Solid carbide construction for durability and consistent cutting performance
• 5/32-inch cutting diameter suited for detailed, small-scale material removal
• 1/8-inch shank diameter fits standard die grinders and rotary tool chucks
• Uncoated head for broad compatibility across ferrous and non-ferrous materials

Compatibility

Designed as an OEM-style replacement bur conforming to industry specification SD-52, compatible with standard 1/8-inch collet die grinders and rotary tools used in metalworking and fabrication.

Installation Notes

Installation is performed by machinists or fabricators using standard die grinder or rotary tool equipment. Secure the 1/8-inch shank fully into the collet and tighten to the tool manufacturer's specification before operation. Inspect the bur for chips or damage before each use and do not exceed the rated RPM of the tool or bur. Eye protection and appropriate PPE should be worn whenever abrasive rotary tools are in use.
