Features:
High speed steel is a tool material that can be used to make cutting metal materials at a higher temperature as it is used after heat-tempering process, such as tempering, and then sanded to compensate for low softening resistance at high temperatures.
How to Use:
Normally drilling, the size of this step drill is a tool that allows you to drill holes in one size, but the holes are expanded sequentially from small to large holes, so it is a tool that allows you to modify the magnification of multiple sizes and holes. So you dont have to use multiple drills, so its more efficient. The step drill is mainly used with an impact screwdriver. Slowly press the impact driver until the size you want to drill a hole. NEVER OPEN! This may cause injury or damage.
