Hertel SZ0025B Abrasive Bur Ball Double Cut Solid Carbide

Product Description

The HERTEL SZ0025B is a solid carbide abrasive bur with a ball head shape, designed for precision material removal and deburring in metalworking and fabrication applications. It features a 1/8 inch cutting diameter and a 1/4 inch shank diameter, making it compatible with standard die grinders and rotary tools. The double cut tooth style increases material removal rate while producing a smoother finish compared to single cut configurations. This bur is left uncoated, with the solid carbide construction providing hardness and wear resistance. It is typically used by machinists, tool and die makers, and metal fabricators working with ferrous and non-ferrous materials.

The SZ0025B suits applications in metal grinding, weld blending, port work, mold and die finishing, and general deburring tasks. The ball profile allows access to contoured surfaces, recesses, and curved geometry where flat or cylindrical profiles cannot reach. It is well suited for both bench-mounted rotary tools and handheld pneumatic die grinders in shop and field environments. Solid carbide construction makes it appropriate for harder materials including hardened steel, cast iron, and tool steel.

Key Features

• Ball head shape for work on curved, recessed, and contoured surfaces
• 1/8 inch cutting diameter for detail and precision material removal
• Double cut tooth style for faster stock removal with improved surface finish
• Solid carbide head material for durability in hard and abrasive materials
• 1/4 inch shank diameter fits standard die grinders and rotary tool collets
• Uncoated finish — no coating delamination risk during extended use

Compatibility

Designed as a replacement-style abrasive bur conforming to SD-12 industry specification, fitting standard 1/4 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 procedures. Ensure the tool is fully powered off and depressurized before inserting or removing the bur from the collet. Secure the shank firmly in the collet to the manufacturer-specified tightening method to prevent slippage during operation. Always wear appropriate eye protection and follow shop safety guidelines when operating rotary cutting tools.
