Description

The DUWELL HSS Step Drill Set (3 Pieces) is a versatile and high-performance drilling solution designed for precision, durability, and efficiency. This set includes three high-speed steel (HSS) step drill bits covering a wide range of hole sizes, making it ideal for professionals, technicians, and DIY users.

Each step drill bit is manufactured from premium HSS material and finished with a gold titanium coating, which enhances cutting performance, reduces heat buildup, and significantly extends the lifespan of the tool. The stepped cone design allows smooth and controlled drilling, enabling multiple hole sizes to be created with a single bit while minimizing burrs and material damage.

The set typically covers the following size ranges:

4–12 mm
4–20 mm
4–32 mm

These step drills are suitable for use on steel sheets, aluminum, copper, brass, plastic, PVC, fiberglass, and thin wood. They are especially effective for enlarging existing holes, deburring edges, and creating clean, round openings for electrical installations, cable routing, and metal fabrication work.

Packaged on a durable retail blister card, the DUWELL HSS Step Drill Set is easy to store, transport, and display. Compatible with most standard electric drills and drill presses, this set offers reliable performance, accuracy, and versatility for workshop, industrial, and home use.
