Quick Facts

Premium M42 8% Cobalt Steel Drill Bit, 68-70 HRC

3-Step Design for Efficient Cutting

Our 3-step design makes it perfect for cutting through stainless steel, hard metals, aluminum, and plastic. You can expect to drill up to five times faster than with traditional drill bits, making your work more efficient and enjoyable.

Cost-Effective

Despite the higher cost, the cost per hole is significantly lower when using a cobalt drill bit. This is because it can produce many more holes than other types of bits, saving you time and money in the long run.

Sharp Bit Edge

The sufficiently sharp bit edge ensures that you cut metal material into long strips of iron chips, rather than slowly grinding through the material with a blunt drill bit. This makes the process of drilling much faster and more effective.
