Heavy duty nitride surface treatment increases hardness for drilling stainless steel and other hard metals
Jobber length drill bit has a midrange drilling depth
High-speed steel (HSS) provides hardness for wear resistance
Black and gold oxide finish resists corrosion and increases the hardness of the drill bit for additional wear resistance
Self-centering 135-degree split point penetrates hard material without a pilot hole and produces small chips to reduce clogging
