This Cobalt Drill Bit is designed for high tensile steels and challenging alloys, with a 135° split point. Cobalt Alloy bits offer enhanced resistance to heat and stress, allowing for faster rotation without overheating. The 135° split point reduces thrust requirements and prevents drill point wandering, making it suitable for portable drills or drill presses. Compared to High Speed Steel bits, Cobalt Alloy bits maintain sharpness for a longer duration, leading to cost and time savings in workshop applications.
