Drill Bit Hss Turbo Point 11.0mm 1/card

Overview

Ø11mm 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 .
