Steel Blue

KnKut Steel Blue Jobber Length Drill Bits are built from NAS-grade high-speed steel and finished with a blue nanocomposite coating engineered for extreme hardness, corrosion resistance, and heat resistance. The coating lets the bit run hotter and longer without breaking down extending tool life on demanding materials.

Available in fractional sizes, these bits are the step up from standard HSS when you're drilling stainless steel, high-alloy metals, or anything that eats through cheaper tooling fast. Jobber length for general-purpose reach. Individual bits and sets available. USA made.
