Hertel SZ008IC Abrasive Bur Inverted Cone 3/16 in Carbide

Product Description

The HERTEL SZ008IC is a solid carbide abrasive bur with an inverted cone and flat end head geometry, manufactured to SN-53 industry specification. It features a 3/16 inch cutting diameter and a 1/4 inch length of cut, with a double cut tooth style for aggressive stock removal and smooth finishing across a range of materials. The 1/8 inch shank diameter suits standard die grinders, rotary tools, and pneumatic handpieces used in metalworking, fabrication, and maintenance applications. At 0.0077 pounds, it is a compact, single-piece tool designed for precision deburring, contouring, and cavity work in tight geometries.

This bur is suited for use in metal fabrication shops, tool and die work, welding preparation, and general maintenance machining. The inverted cone with flat end profile is commonly used to create undercuts, back-chamfer holes, and clean up angular surfaces where straight or ball-end profiles cannot reach. It is appropriate for use on ferrous metals, non-ferrous metals, and hardened alloys. The double cut configuration removes material efficiently while reducing chatter, making it a practical choice for both production and detail work performed by machinists, maintenance technicians, and fabricators.

Key Features

• Inverted cone with flat end head shape per SN-53 industry specification
• Double cut tooth style for efficient material removal and reduced chatter
• Solid carbide head construction for hardness and wear resistance
• 3/16 inch cutting diameter with 1/4 inch length of cut
• Uncoated head for broad material compatibility
• 1/8 inch shank fits standard die grinders and rotary handpieces

Compatibility

Designed as a standard 1/8 inch shank rotary bur compatible with die grinders, pneumatic handpieces, and rotary tools accepting 1/8 inch collets.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder or rotary tool equipped with a 1/8 inch collet. Ensure the tool is fully powered down and the collet is properly tightened before operation. Inspect the bur for cracks or chipping before each use and do not exceed the recommended RPM rating of the host tool. Eye protection and appropriate PPE are required when operating rotary burs.
