Hertel SZ2002B Abrasive Bur Ball SD-5NF Solid Carbide

Product Description

The HERTEL SZ2002B is a solid carbide abrasive bur with a ball head geometry, designed for material removal, deburring, and surface blending in metalworking and fabrication applications. Built to industry specification SD-5NF, this bur features an Aluma Cut tooth style, which is engineered for efficient chip evacuation and reduced loading when working aluminum and other non-ferrous metals. The cutting head measures 1/2 inch in diameter and mounts on a 1/4 inch shank. Machinists, tool and die technicians, and fabricators use this bur in pneumatic or electric die grinders for contouring and finishing work in tight or contoured areas.

This bur suits applications in metal fabrication shops, maintenance and repair operations, and production environments where non-ferrous materials such as aluminum, brass, and softer alloys require controlled stock removal or surface prep. The ball head profile makes it well suited for concave surface blending, cavity work, and weld cleanup in recessed areas. It is sold individually and is compatible with standard 1/4 inch collet die grinders used across industrial and trade settings.

Key Features

• Ball head geometry for concave surface blending and cavity profiling
• Aluma Cut tooth style designed to reduce chip loading on non-ferrous metals
• Solid carbide construction for hardness and wear resistance under continuous use
• 1/2 inch cutting diameter with 1/4 inch shank fits standard die grinder collets
• Meets industry specification SD-5NF for consistent dimensional standards
• Uncoated head for straightforward inspection and reconditioning assessment

Compatibility

Designed for use with pneumatic or electric die grinders fitted with a standard 1/4 inch collet. Conforms to industry specification SD-5NF for dimensional interchangeability with other SD-5NF rated burs.

Installation Notes

Installation should be performed by a qualified machinist or fabrication technician familiar with rotary cutting tools. Ensure the die grinder is fully depowered and disconnected from the air supply or electrical source before changing burs. Insert the 1/4 inch shank fully into the collet and tighten securely before operation. Always wear appropriate eye protection and follow the grinder manufacturer's rated RPM limits for the tool diameter in use.
