Our stepped point cobalt drill bits stop bit wandering completely and remove the requirement for pilot holes. They deliver smoother drilling starts and faster cutting speeds, outperforming all standard conventional drill bits by a wide margin.

The blue oxide surface coating reduces friction and restricts excessive heat generation. This boosts the service life of drill bits while enabling clean, high-efficiency cutting performance.

Built with a mechanic’s short-length profile for easy reach in tight, confined working areas. The 3-flat shank locks the bit firmly to avoid slipping, allowing fast, hassle-free bit swaps.

Ideal for enlarging pre-drilled holes, these bits feature exceptional toughness for heavy-duty drilling tasks across stainless steel, general metal and timber materials.

We stand firmly behind our premium craftsmanship. Each set comes with a sturdy storage case for secure storage and easy transport. All product issues will be fully resolved for you. Shop without worry and add the set to your cart today!
