In a nutshell
The right choise for
With the Fein Vario M27 machine tap, you cut precise right-hand metric threads in through holes up to a cutting depth of 40 mm. Its hss construction combined with a tough TiAlN coating minimizes friction and delivers heat resistance up to 800 °C for extended tool life. Thanks to the secure hex shank, the tap stays locked without slipping during high-torque work. With a 3 mm pitch, it cuts clean threads smoothly into alloyed and unalloyed steel up to 900 N/mm², aluminium, and brass. This gives you the speed, control, and durability needed for demanding metal fabrication tasks.
