Fein VARIO TiAlN-Coated 1/2"-13 UNC Through-Hole Tapper The Fein VARIO 1/2"-13 UNC tapper is a heavy-duty industrial solution designed for high-torque threading in through-hole applications. Forged from ultra-high-strength tool steel and hardened to an impressive 64 HRC, this tool is built to survive the rigors of high-production environments. It features specialized cutting geometries specifically engineered for impact wrench compatibility, allowing for rapid threading that traditional taps cannot handle. The Titanium Aluminum Nitride (TiAlN) coating provides a low-friction, heat-resistant barrier, enabling the tool to maintain its edge while operating at high speeds in materials with tensile strengths up to 130 ksi. Whether working with alloyed steels, aluminum, or brass, this tapper delivers professional-grade precision and unmatched tool longevity.
Features
Advanced TiAlN Coating: Features a high-performance Titanium Aluminum Nitride coating that resists heat buildup and reduces friction during high-speed operation.
Impact Wrench Compatible: Designed with robust cutting geometries that safely handle the rotational impacts and high torque of power drivers.
64 HRC High-Strength Steel: Constructed from premium-grade tool steel for extreme hardness and a significantly longer service life than standard carbon steel taps.
High-Tensile Material Specialist: Engineered to effectively thread unalloyed and alloyed steels with tensile strengths up to 130 ksi.
Optimized for Through-Holes: Features a design that efficiently drives chips forward and out of the hole, preventing binding and tool breakage.
Multi-Material Versatility: Provides clean, precise 1/2"-13 UNC threads in high-strength steel, aluminum, and brass workpieces.
Thermal Stability: The specialized coating allows for continuous use at higher temperatures without compromising the tool's structural integrity.
