Hertel SZ2001B Abrasive Bur Ball SD-3NF Solid Carbide

Product Description

The HERTEL SZ2001B is a solid carbide abrasive bur with a ball head shape, designed for material removal, deburring, and surface finishing in metalworking and fabrication applications. It conforms to the SD-3NF industry specification and features an Aluma Cut tooth style, which is engineered for efficient cutting in aluminum and other non-ferrous metals. The 3/8-inch cutting diameter head is uncoated solid carbide, and the bur mounts on a 1/4-inch diameter shank for use in standard die grinders and rotary tools. This is a single-piece unit suited for bench technicians, machinists, and maintenance professionals who need precise burring performance.

This bur is appropriate for shop and field use where controlled material removal is required on aluminum, soft metals, and similar non-ferrous workpieces. The Aluma Cut geometry reduces chip clogging and heat buildup during extended cutting passes. The ball profile allows access to contoured surfaces, cavities, and radiused features that flat or cylindrical burs cannot reach. It is a standard tool in fabrication shops, HVAC sheet metal work, and general mechanical maintenance environments.

Key Features

• Ball head shape for access to curved surfaces, cavities, and contoured features
• Aluma Cut tooth style optimized for aluminum and non-ferrous metals
• Solid carbide head construction for wear resistance and cutting durability
• Uncoated head surface compatible with standard die grinder speeds
• Conforms to SD-3NF industry specification for direct replacement sourcing
• 1/4-inch shank fits the majority of standard die grinders and rotary tools

Compatibility

Designed as a standard SD-3NF specification ball bur compatible with die grinders and rotary tools accepting a 1/4-inch shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard die grinder collet rated for 1/4-inch shank tooling. Confirm the grinder is powered off and the collet is fully tightened before operation. Always wear appropriate eye protection and follow shop safety protocols when using rotary abrasive tooling. Do not exceed the maximum RPM rating of the grinder or use the bur on ferrous materials where Aluma Cut geometry is not intended.
