5PCS Amber Color HSS Co Twist Drill Bits Set with Plastic Box
Advantages
Material: HSS-Co drill bits are made from a combination of high-speed steel and cobalt, which provides increased hardness and heat resistance compared to standard HSS drill bits.
Versatility: HSS-Co drill bits are suitable for drilling through a wide range of materials, including stainless steel, cast iron, aluminum, and other hard materials.
Increased durability: The cobalt content in the drill bits improves their strength and wear resistance, allowing them to withstand high drilling forces and extended use.
High-speed drilling: HSS-Co drill bits are designed for high-speed performance, making them suitable for use with power drills and allowing for faster and more efficient drilling.
Precision and accuracy: The drill bits in the set may feature a 135-degree split point design, which provides better accuracy and reduces the risk of slipping or walking during drilling.
