Hertel SZ0012B Abrasive Bur Ball Double Cut Solid Carbide

Product Description

The HERTEL SZ0012B is a solid carbide abrasive rotary bur with a ball head profile, designed for deburring, grinding, shaping, and surface finishing on a wide range of materials. The ball shape allows access to contoured surfaces, concave profiles, and internal radii where flat or cylindrical tools cannot reach. Built to the SD-42 industry specification, it features a double cut tooth pattern that removes material efficiently while producing a smoother finish than single cut. The 0.125 inch cutting diameter and 0.125 inch shank diameter make it suited for precision work in die grinders and rotary tool systems. Solid carbide construction delivers hardness and wear resistance well beyond high-speed steel alternatives.

This bur is used by machinists, toolmakers, pipefitters, and fabricators in applications that require controlled material removal in tight or curved geometries. Common uses include weld blending on steel and stainless, port matching on cast components, flash removal on castings, and finishing work on aluminum, titanium, and hardened steels. The compact 0.125 inch shank fits standard collets on pneumatic die grinders, electric rotary tools, and flexible shaft machines used in both shop and field environments.

Key Features

• Ball head profile provides access to concave surfaces, radii, and contoured workpieces
• Double cut tooth pattern for faster stock removal and improved surface finish
• Solid carbide head resists heat and wear on hardened metals, stainless, and cast materials
• Uncoated finish allows direct visual inspection of cutting edge condition
• Conforms to SD-42 industry specification for consistent dimensional standards
• 0.125 inch shank fits standard collets on most die grinders and rotary tools

Compatibility

Designed as an OEM-style replacement rotary bur for use in any die grinder, rotary tool, or flexible shaft machine accepting a 0.125 inch collet or chuck.

Installation Notes

Installation is performed by machinists and fabricators using standard collet tooling. Ensure the tool is fully de-energized and the collet is released before inserting or removing the bur. Secure the shank to the full depth of the collet and tighten to the tool manufacturer's specified torque using the appropriate collet wrench. Always wear appropriate eye protection and ensure workpiece is secured before operating.
