Our M42 8% cobalt drill bits are designed for stainless steel, hard metals, aluminum, and plastic, providing exceptional heat, wear, and chip resistance with long tool life. Featuring a 3-step design and a 135-degree split point, these bits deliver precise, efficient cutting and produce long iron chip strips rather than grinding. Capable of running three to five times faster than standard bits, they reduce overall cost per hole while maintaining performance and durability, making them ideal for professional and DIY metalworking tasks.
