Tri-Ultra Cut drills outlast and outperform low-grade M35 5% Cobalt every time. They are made from special hi-molybdenum tool steel and are heat treated to 66 Rockwell. They feature oxidized black and gold surface, which provides maximum lubricity and higher heat handling. The thinner web construction means these tools will continually cut beneath the chip to cut softer steel.
Tri-Ultra Cut drills have a significantly longer cutting life that uses less torque and runs cooler. They have a tighter hole size and stop drill walking and chuck slippage.
