The Cleveland C15970 Q-AMD 3780 is a high-performance cobalt jobber drill bit designed for heavy-duty drilling in tough materials. Its short flute length and steam oxide finish provide the rigidity and heat resistance necessary to prevent tool deflection and premature wear in demanding industrial applications.
- Cobalt construction ensures superior heat resistance and maintains a sharp cutting edge when working with hard or abrasive metals.
- The short flute design increases tool strength and rigidity, reducing the risk of breakage during high-torque operations.
- Steam oxide surface treatment improves lubricant retention and reduces friction for smoother chip evacuation and extended tool life.
This drill bit is ideal for machinists and maintenance professionals in the automotive, aerospace, and metal fabrication industries who require a durable tool for drilling through stainless steel, titanium, and other high-strength alloys.
- Size: 5/16 in
- Flutes: 2
- Series: Q-AMD 3780
