The turbo point drill is designed for professional individuals who desire an aggressivecut 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.

When drilling hard metals, always use a coolant/lubricant. We recommend usingCT-90.
