Professional 3-piece step drill set with titanium-coated HSS 4241 steel, featuring diameters from 3-20mm for precision drilling in steel, stainless steel, and plastic materials with automatic centering and clean edge results.
The YATO YT-44731 3PCS Step Drills Set is a professional-grade drilling solution designed for precision work in various materials. This comprehensive set includes three step drills with diameters ranging from 3 to 20mm, manufactured from high-quality HSS 4241 steel and coated with titanium nitride for enhanced durability and extended tool life. Each drill features automatic centering capabilities on rounded and slippery surfaces, ensuring accurate hole placement and clean drilling results without burrs.
This set is specifically engineered for drilling in high-quality stainless steel, structural steel, cold rolled steel, non-ferrous metals, steel sheets, and plastic materials. The titanium nitride coating significantly increases the lifespan of the drills while maintaining superior cutting performance. The set comprises three drills: 3-12mm with 10 grades (3, 4, 5, 6, 7, 8, 9, 10, 11, 12mm), 4-12mm with 5 grades (4, 6, 8, 10, 12mm), and 4-20mm with 9 grades (4, 6, 8, 10, 12, 14, 16, 18, 20mm).
The drills feature fast heat dissipation when drilling in hard materials, reducing thermal stress and preventing tool degradation. With a maximum cutting capacity of 4mm and cylindrical tool holder type, these step drills are ideal for both professional workshops and serious DIY enthusiasts. The clean edges produced by these drills eliminate the need for additional deburring, saving time and improving overall work efficiency.
