High-Performance Parabolic Jobbers Length Cobalt Drills, 130
- Run in manual or CNC machines for deep hole applications. Flute design optimizes coolant flow and chip evacuation, reducing cycle time. 130 point reduces thrust requirements and provides accurate hole location and dimensional accuracy. Heat-resistant cobalt substrate allows drill to run at elevated temperatures. Recommended for alloyed steel, aerospace alloys, and other heat-generating applications. List# 622 drills feature nitrided margins and polished flutes. List# 658 drills feature TiN coating for additional resistance to wear and heat.
