Fein VARIO TiAlN-Coated 3/4"-10 UNC Through-Hole Tapper The Fein VARIO 3/4"-10 UNC tapper is a powerhouse industrial threading tool designed for large-scale through-hole applications in heavy structural and mechanical engineering. Constructed from ultra-high-strength tool steel and hardened to an exceptional 64 HRC, this tapper is built to withstand the massive torque loads required for 3/4" threading. It features specialized cutting geometries that are uniquely compatible with impact wrench systems, enabling mechanical threading at speeds that would compromise standard taps. The Titanium Aluminum Nitride (TiAlN) coating provides a low-friction, high-thermal-stability barrier, allowing the tool to perform flawlessly in high-strength steels up to 130 ksi. This tapper is the ultimate solution for heavy-duty fabrication, ship building, and infrastructure maintenance where maximum efficiency and tool longevity are non-negotiable.

Features
  • Extreme Heat Resistance: The TiAlN (Titanium Aluminum Nitride) coating allows for high-speed operation by creating a thermal shield that protects the cutting edge.
  • Impact Wrench Compatible: Features a ruggedized shank and cutting geometry specifically engineered to absorb the percussive forces of high-torque impact drivers.
  • Ultra-Hard 64 HRC Steel: Forged from premium tool steel for maximum wear resistance, ensuring the tool maintains its profile through repeated use in abrasive materials.
  • 130 ksi Tensile Capacity: Engineered to successfully tap threads in high-strength alloyed and unalloyed steels that typically cause standard taps to fail.
  • Advanced Chip Evacuation: Optimized for through-holes, driving chips forward and out to prevent clogging, binding, and potential tool breakage.
  • Low Friction Surface: The specialized coating minimizes drag, reducing the energy required for each rotation and extending the battery life of cordless tools.
  • Versatile Heavy-Duty Tapping: Delivers precise 3/4"-10 UNC threads across a variety of substrates, including structural steel, aluminum, and brass.
