Hertel SZ20001B Abrasive Bur Ball 1/4 Inch Solid Carbide

Product Description

The HERTEL SZ20001B is a solid carbide abrasive bur with a ball head shape, designed for material removal, blending, and deburring in metalworking and fabrication applications. Conforming to the SD-1MM industry specification, this bur features a 1/4-inch cutting diameter and a single-cut tooth style that produces efficient stock removal with manageable chip loads. The uncoated solid carbide head delivers consistent performance on ferrous and non-ferrous metals, composites, and hard plastics. With a 6.00 mm shank diameter and a 2-inch overall length, it is sized for use in standard die grinders, rotary tools, and pneumatic handpieces used by machinists, tool and die makers, and maintenance technicians.

This bur is suited for precision material removal tasks in both production and maintenance environments. Typical applications include weld blending, port work, cavity preparation, and contour finishing where a ball-end geometry is required to reach curved or concave surfaces. The SD-1MM specification makes it a direct fit for standard tooling setups in general metalworking, aerospace fabrication, and mold and die work. It is sold individually, making it practical as a replacement for a single worn or damaged tool.

Key Features

• Ball head shape for access to curved, concave, and contoured surfaces
• Solid carbide construction for durability on hard metals and composites
• Single-cut tooth style for efficient stock removal with reduced chatter
• Uncoated head for direct compatibility across a broad range of workpiece materials
• SD-1MM industry specification for consistent tooling standardization
• 6.00 mm shank fits standard die grinder and rotary tool collets

Compatibility

Designed as an OEM-style replacement bur conforming to the SD-1MM industry specification, suitable for use with standard die grinders and rotary tools accepting a 6.00 mm shank.

Installation Notes

Installation and use of this bur should be performed by qualified machinists or fabrication technicians familiar with rotary cutting tool safety. Ensure the tool holder or collet is fully de-energized and at a complete stop before inserting or removing the bur. Verify that the shank is fully seated and the collet is properly tightened before operation. Always wear appropriate eye protection and follow shop safety protocols when operating rotary burs at speed.
