The set contains three stepped drills with working ranges of 4–12 mm, 4–20 mm and 4–39 mm. This makes it easy to choose the right drill according to the required hole diameter.
The sizes of the individual steps are marked directly on the surface of the drills. The markings help with continuous checking of the diameter of the hole being drilled.
The set includes a practical case that helps keep the drills together during storage and transport.
Stepped cone drills are a practical choice for creating and gradually enlarging holes without the need to frequently change tools. Each drill offers multiple diameters in a single design, making work easier during assembly, workshop modifications and home use.
The drills are made of high-speed HSS steel and feature a titanium coating. The gold finish is complemented by spiral flutes for material removal and marked sizes for easy checking of the required diameter.
