      Features and benefits

      • Kenna Universal™ drills with through coolant.

      • Multipurpose SC drill engineered to deliver superior performance in steel, cast iron, stainless steel, and other applications, making it ideal for small- and medium-sized shops.

      • The universal application profile reduces tool change times and the number of drills in inventory.

      • It's a problem solver that works everywhere.

      • Four-margin land design provides good alignment and stability in tough drilling applications — even when drilling through cross holes.

      • KC7315™ grade is a multilayer, TiAlN-based coating with high hot hardness enables 30% higher cutting speeds and constant tool life.
