M35 Cobalt Material: Made from high-performance M35 cobalt steel, these drill bits provide enhanced durability and heat resistance, making them ideal for drilling through tough materials like stainless steel and hard metals.
Stepped Point Design: The unique stepped point design ensures accurate starts without walking or slipping, providing cleaner and more precise holes, which makes it easier to drill through metals and other materials with minimal effort.
Three Flat Shank: Equipped with a three-flat shank, these drill bits offer a firm grip in the drill chuck, preventing slippage and ensuring smooth, stable drilling, which improves control and reduces the risk of mistakes during high-torque applications.
Gold Oxide Coating: The gold oxide coating on these bits improves wear resistance and enhances overall tool life, while also reducing friction and heat buildup, allowing for faster and smoother drilling through tough materials like stainless steel and aluminum.
