The Somta Parabolic Flute Jobber Drill, TiAlN coated and 4.2 mm in diameter, is a precision drilling tool designed for dependable, repeatable holes across a variety of materials. Part of the 164X series, it combines a parabolic flute geometry with a tough drill body to deliver clean results with less effort.
The parabolic flute design enhances chip evacuation and lowers cutting forces, helping you maintain steady feeds and smoother drilling. Coupled with the TiAlN coating, which provides exceptional hardness, heat resistance, and lubricity, this drill can run at higher speeds with reduced wear. It’s well suited for drilling stainless steel, alloy steels, cast iron, and other demanding materials, making it a versatile choice for shops and job sites.
- Parabolic flute for efficient chip evacuation: Chips clear quickly from the cutting edge, reducing heat buildup and cutting forces for smoother drilling and longer tool life.
- TiAlN coating for extended life: Hard, heat-resistant coating lowers friction and keeps the edge cooler, enabling higher speeds and better durability in tough materials.
- Versatile 4.2 mm size for wide applications: A reliable, commonly used hole diameter that delivers consistent performance in stainless steel, alloy steels, cast iron, and other challenging workpieces.
This drill is designed to help you complete more work with fewer tool changes, fewer reworks, and more predictable drilling results. The combination of parabolic flute technology and the TiAlN coating supports faster cycles, improved hole quality, and greater confidence when tackling demanding materials.
