Hertel SZ0028CW Abrasive Bur SC-4 Cylinder Radius End

Product Description

The HERTEL SZ0028CW is a solid carbide rotary abrasive bur conforming to the SC-4 industry specification with a cylinder with radius end head shape. Designed for aggressive material removal and finishing work, this double cut bur features a 7/16-inch cutting diameter and a 1/4-inch shank diameter with a 1-inch length of cut. The double cut tooth pattern produces faster stock removal and leaves a smoother finish compared to single cut styles. Machinists, tool and die makers, and fabrication professionals use this bur for deburring, shaping, and surface blending on metals, plastics, and composite materials.

The SC-4 cylinder with radius end geometry is well suited for contouring curved surfaces, cleaning up weld seams, and working into blind cavities where a flat-ended cylinder cannot reach the full profile. The 1/4-inch shank is compatible with standard die grinders, air tools, and rotary tool collets commonly found in machine shops, maintenance environments, and metal fabrication facilities. This bur is appropriate for both light-duty finishing passes and heavier roughing operations depending on RPM and feed pressure applied by the operator.

Key Features

• SC-4 industry specification cylinder with radius end head shape for contoured surface work
• Double cut tooth style for fast stock removal with a smoother resulting finish
• 7/16-inch cutting diameter and 1-inch length of cut for mid-range material engagement
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Solid carbide construction provides hardness and wear resistance across ferrous and non-ferrous materials
• Uncoated head — no coating to chip or peel during aggressive use

Compatibility

Designed as an OEM-specification SC-4 abrasive bur for use with 1/4-inch collet die grinders and rotary tools in machine shop, fabrication, and maintenance applications.

Installation Notes

Install the 1/4-inch shank into a properly sized collet and tighten securely before operating. Always verify the die grinder or rotary tool RPM rating does not exceed the maximum rated speed for the bur diameter in use. Wear appropriate eye protection and gloves when operating rotary carbide burs. Inspect the bur for chips or cracks before each use and discard any damaged tooling.
