Hertel SZ0027B Abrasive Bur Ball Double Cut Solid Carbide

Product Description

The HERTEL SZ0027B is a ball-shaped abrasive carbide bur designed for material removal, deburring, and surface finishing in metalworking and fabrication applications. Built to industry specification SD-1, this bur features a 0.25-inch cutting diameter and a double-cut tooth pattern that aggressively removes stock while producing a smoother finish than single-cut alternatives. The solid carbide head delivers the hardness and wear resistance required for extended use on ferrous and non-ferrous metals. Machinists, toolmakers, and die grinders operators install this bur in pneumatic or electric rotary tools for precision material removal work.

The SZ0027B is suited for deburring, blending, and shaping operations in manufacturing, tooling, and repair environments. Its 0.25-inch shank diameter fits standard die grinder collets and rotary tool chucks. The 7/32-inch length of cut makes it well-suited for working in moderate-depth cavities, contoured surfaces, and recessed areas where control and access are equally important. This bur is appropriate for both production and maintenance settings handling hardened alloys and general-purpose metals.

Key Features

• Ball head profile per industry specification SD-1 for contour finishing and concave surface work
• Double-cut tooth style for faster stock removal and reduced chatter
• Solid carbide head for superior hardness and extended tool life
• Uncoated head for compatibility across a broad range of base materials
• 0.25-inch shank fits standard die grinder and rotary tool collets
• Compact 7/32-inch length of cut for working in restricted or recessed areas

Compatibility

Designed as an OEM-style replacement bur for use in standard 1/4-inch collet die grinders and rotary tools used in metalworking, fabrication, and maintenance applications.

Installation Notes

Secure the shank fully into the collet and tighten to the tool manufacturer's specified torque before operation. Disconnect or power down the rotary tool completely before changing burs. Always operate within the RPM rating of the rotary tool for the bur size in use. Eye protection and appropriate PPE are required during carbide bur operation per standard shop safety practice.
