Steel Blue
KnKut Steel Blue drill bit sets give you a full range of blue-coated bits in one case — NAS high-speed steel with a blue nanocomposite coating for extreme hardness, and a 135° split point that starts without a center punch for clean, fast drilling in tough metals. Every set is USA made.
Need single sizes instead of a full set? Shop our individual Steel Blue Drill Bits.
