Application:

The drill bit is made from HSS (hi-speed steel) and is precision fully ground at 135° with a split point. The drill bit can be used to drill materials such as iron, steel, non-ferrous metals and plastics.

Advantages:

Standard HSS 118° angle point drill bits are designed as an all purpose drill bit and it will cut most materials.
