Fein 4-Piece Vario Tapper Set 63110047010

Fein VARIO 4-Piece Professional Impact Tapper Set This premium, four-piece industrial set provides a comprehensive threading solution for the most common heavy-duty fasteners, including 5/16", 3/8", 1/2", and 5/8" diameters. Each tool is meticulously engineered from ultra-high-strength tool steel and heat-treated to a rock-solid 64 HRC, ensuring maximum durability and edge retention in high-volume production environments. Designed specifically for the rigorous percussion of impact wrench systems, these tappers feature specialized cutting geometries that allow for rapid mechanical threading without the structural risk of shattering. Every piece in the set is finished with a Titanium Aluminum Nitride (TiAlN) coating, which acts as a thermal shield and friction-reducer, enabling the tools to maintain peak performance at high speeds in materials with tensile strengths up to 130 ksi. Neatly organized in protective cylindrical packaging, this versatile kit is the essential choice for structural steel fabrication, automotive assembly, and industrial maintenance involving alloyed steels, aluminum, or brass.
