Hertel SZ0020C Abrasive Carbide Bur Cylinder SA-14

Product Description

The HERTEL SZ0020C is a solid carbide abrasive bur with a cylinder and flat end head geometry, conforming to industry specification SA-14. It features a 3/16 inch cutting diameter with a 5/8 inch length of cut and mounts on a standard 1/4 inch shank. The single cut tooth style is suited for fast material removal on ferrous and non-ferrous metals, plastics, and composites. Machinists, tool and die makers, and maintenance technicians use this bur for deburring, shaping, and surface finishing in confined areas where rotary tool access is needed. The uncoated solid carbide construction provides consistent edge retention across a range of workpiece materials.

This bur is used in die grinders, rotary tools, and flexible shaft machines in job shop, maintenance, and fabrication environments. The cylinder with flat end profile allows side cutting along workpiece walls as well as plunge cutting on flat surfaces. Typical applications include weld cleanup, port matching, mold finishing, and edge breaking on cast or machined components. The 1/4 inch shank diameter fits the collets standard to most air and electric die grinders used in industrial and trade settings.

Key Features

• Solid carbide head construction for extended wear life compared to steel burs
• Cylinder with flat end geometry enables both side and end cutting passes
• Single cut tooth pattern delivers smooth finishes and efficient chip clearance
• 3/16 inch cutting diameter with 5/8 inch length of cut for detail work in tight areas
• Uncoated head for broad material compatibility without coating adhesion concerns
• 1/4 inch shank fits standard die grinder collets without adapters

Compatibility

Designed as an SA-14 industry-specification cylinder flat end carbide bur compatible with die grinders and rotary tools accepting a 1/4 inch shank collet.

Installation Notes

Installation is performed by machinists or maintenance technicians using a die grinder or rotary tool. Ensure the tool is powered off and depressurized before inserting or removing the bur from the collet. Tighten the collet to the tool manufacturer's specified torque range using the appropriate collet wrench. Always wear appropriate eye protection and secure the workpiece before operating the rotary tool at speed.
