Introduction of step drills

Step drill, also known as step drill or pagoda drill, is mainly used for drilling thin steel plates within 3mm. One drill bit can replace multiple drill bits.

According to the different processing conditions, the surface coating treatment can be carried out to prolong the service life of the tool and enhance the durability of the tool.

Application:

The products can be used in automobile processing, aerospace, sheet metal processing, electrical installation and maintenance and other industries. At the same time, the products are easy to carry and can be used with hand electric drills and other tools for high-altitude operations.
