Hertel SZ2001O Abrasive Bur Oval 3/8 in Aluma Cut Carbide

Product Description

The HERTEL SZ2001O is a solid carbide abrasive bur with an oval head profile, designed for material removal, deburring, and contouring in metalworking and fabrication applications. The bur features an Aluma Cut tooth style, which produces a shearing action that reduces heat buildup and chip loading when working aluminum, soft metals, and non-ferrous materials. The cutting head measures 3/8 inch in diameter with a 5/8 inch length of cut. The 1/4 inch shank diameter fits standard rotary die grinders and flexible shaft machines. The head is uncoated solid carbide, offering consistent cutting geometry throughout the tool life.

This bur is suited for die grinding operations in metal fabrication shops, maintenance and repair environments, and production deburring setups. The oval head shape allows access to contoured surfaces, internal radii, and irregular profiles where flat or cylindrical tools cannot reach. The Aluma Cut configuration is particularly effective on aluminum, brass, copper, and other soft or gummy metals where standard double-cut burs tend to load up. Licensed machinists, tool and die technicians, and fabricators are the primary installers of this type of tooling.

Key Features

• Oval head profile for contouring, blending, and accessing curved or irregular surfaces
• Aluma Cut tooth style minimizes chip loading on aluminum and non-ferrous metals
• Solid carbide construction provides rigidity and consistent cutting performance
• 3/8 inch cutting diameter with 5/8 inch length of cut
• 1/4 inch shank fits standard die grinder collets
• Uncoated head — no coating interference on critical surface finishes

Compatibility

Designed as an OEM-style replacement bur conforming to industry specification SE-3NF, compatible with 1/4 inch collet die grinders and rotary tool holders used in standard metalworking and fabrication setups.

Installation Notes

Installation is performed by machinists or fabricators using standard die grinder equipment. Ensure the grinder is powered off and the collet is fully released before inserting or removing the bur. Insert the shank fully into the collet and tighten securely before operation. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary carbide burs.
