Description
The Somta Parabolic Flute Jobber Drill TiAlN Coated, 3.5 mm, is a high-performance drilling tool designed for precise hole-making across a range of materials. It’s ideal for engineers, machinists, tradespeople, and hobbyists who need reliable, clean holes with consistent results in everyday workshop and production settings.
Featuring a parabolic flute geometry and a Titanium Aluminium Nitride (TiAlN) coating, this drill evacuates chips quickly, reduces cutting forces, and stays cooler under load. The coating also provides outstanding hardness and lubricity, helping you push higher speeds and extend tool life when drilling stainless steel, alloy steels, cast iron, and other challenging materials.
- Parabolic flute design for efficient chip evacuation: Minimizes built-up edge and cutting resistance, enabling smoother drilling, reduced stall, and longer tool life even in tougher materials.
- TiAlN coating for hardness, heat resistance, and lubricity: Cuts friction and limits heat buildup, allowing higher cutting speeds and improved tool longevity across demanding jobs.
- Wide material compatibility with consistent results: Delivers reliable performance in stainless steel, alloy steels, cast iron, and other challenging materials for repeatable hole quality and fewer tool changes.
This drill is a practical, dependable choice for anyone tackling precision drilling tasks. By combining efficient chip evacuation, durable coating performance, and broad material compatibility, it helps improve workflow, reduce downtime, and deliver consistent hole quality from pilot cuts to finishing passes.
