Description
Ø8.5mm HSS turbo point drill bit
Application:
The turbo point drill is designed for professional individuals who desire an aggressive cut in metals. The drill is designed with a standard 118° point, but shaped with a self-centering turbo point for cleaner entry and fast starts.
The drill bit is manufactured from HSS (hi-speed steel) and can be used to drill materials such as iron, steel, non-ferrous metals and plastics.
The shank is designed to have three flattened sides to ensure better grip in a 3-jaw chuck.
TIP:
When drilling hard metals, always use a coolant/lubricant. We recommend using CT-90.
