DRILL BIT HSS TURBO POINT 8.5MM 1/CARD

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.
