Fein 63110046010 VARIO Impact Tapper Set for Through Holes (M8/M10/M12/M14/M16)
The FEIN VARIO Impact Tapper Set for Through Holes is a professional-grade tapping accessory set engineered for high-performance thread cutting with impact wrench and impact driver systems. Designed for industrial fabrication, maintenance and metalworking environments, this VARIO set provides a complete and efficient solution for creating precise metric threads in through-hole applications.
This 5-piece set includes one tapper each in M8 x 1.25 mm, M10 x 1.5 mm, M12 x 1.75 mm, M14 x 2.0 mm and M16 x 2.0 mm, supplied in durable cylindrical packaging for organised storage and professional workflow efficiency. Each tapper is manufactured from high-strength HSS material with a hardness rating of 64 HRC and finished with a TiAlN (titanium aluminium nitride) coating, ensuring long service life, reduced friction and excellent wear resistance even under high-speed impact operation.
Special cutting geometries optimised for impact wrench/drivers enable stable and reliable thread formation while maintaining performance under demanding conditions. The tappers are heat-resistant up to 800°C and suitable for use in non-alloyed and alloyed steels up to 900 N/mm², as well as aluminium and brass. With the VARIO bit shaft interface, the set ensures secure tool engagement and consistent torque transfer for professional tapping performance.
