[Product Information]
- Designed for drilling stainless steel and other hard metals
- Jobber length drill bit has a midrange drilling depth
- Nitride surface treatment on high-speed steel 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 140-degree split point penetrates extra-hard material without a pilot hole and produces small chips to reduce clogging
