Cobalt Pro Drill Bit Set

Description

Product Overview

COBALT PRO DRILL BIT

• For the most part, drill bits are made of high-speed steel.

• This metal is more durable than regular steel, which is why it can handle wood and plastic relatively well.

• However, if you want to puncture tougher metals, then you need a bit that won?t break down or get dull too easily.

• Cobalt is the best option in this case, as it will hold up to higher temperatures and won?t fracture under heavy pressure.

• So, if you?re planning on working with hardened metals, you?ll need a cobalt drill bit.
