Fein VARIO TiAlN-Coated 82° Countersink 5/8" The Fein VARIO 5/8" countersink is a specialized industrial tool designed for precision chamfering and deburring in high-strength metal applications. Forged from ultra-high-strength tool steel and heat-treated to an impressive 64 HRC, this 82-degree countersink is engineered to survive the intense torque and percussion of impact wrench systems. The Titanium Aluminum Nitride (TiAlN) coating provides a formidable thermal barrier and a low-friction surface, allowing the tool to maintain a razor-sharp edge even at the high rotational speeds required for machining high-tensile steels up to 130 ksi. This tool is the ideal solution for structural steelwork, aerospace components, and heavy-duty fabrication where a perfectly recessed, flush finish is required in alloyed steels, aluminum, or brass.

Features
  • Precision 82° Angle: Optimized for standard industrial fasteners to ensure a perfect flush-fit finish in structural metalwork.
  • Advanced TiAlN Coating: Features a high-grade Titanium Aluminum Nitride layer that provides superior heat resistance and a low-friction surface for high-speed operation.
  • Impact Wrench Compatible: Engineered with specialized, ruggedized cutting geometries and a shank designed to handle the percussive forces of power drivers.
  • Ultra-Hard 64 HRC Steel: Manufactured from premium high-strength tool steel for maximum edge retention and resistance to abrasive wear in tough alloys.
  • 130 ksi Material Capacity: Capable of machining high-strength unalloyed and alloyed steels, as well as non-ferrous metals like aluminum and brass.
  • Thermal Stability: The specialized metallurgy ensures the tool retains its tempered hardness even under the intense heat generated by high-speed dry machining.
  • Chatter-Free Performance: Designed with a balanced cutting geometry to provide a smooth, consistent finish without surface vibration or deformation.
