The Yato YT-44742 step drill is engineered for precision drilling in high-grade stainless steel, structural steel, cold rolled steel, non-ferrous metals, steel sheets, and plastics.
It features diameters from 10 mm to 45 mm in 8 steps, a brad point tip for automatic centering on rounded and slippery surfaces, and two spiral flutes that efficiently dissipate chips. The edges of drilled holes remain clean and burr-free, while the titanium nitride coating increases tool life and ensures rapid heat dissipation when drilling hard materials.
The Yato YT-44742 step drill has a triangle shank with 3 flat surfaces, allowing maximum torque transfer and secure grip in the chuck.
