This cutting tool is suitable for drilling and enlarging holes in thin iron plates, aluminum plates, wood, resin, etc.
All tasks such as drilling, enlarging pilot holes, chamfering, and deburring can be done with this set of 3!
The nitrided coating provides smooth friction, reduces frictional heat, improves sharpness, and increases durability.

There are mainly two types of step drills, and the one listed is the straight type.
While spiral types bite into the material better, they can also pull the material in and over-drill holes. Therefore, this straight-type step drill is easier to handle.
