Smooth drilling of holes with various diameters is possible with this wood drill. Center punching is not required, as the cross-ground tip facilitates the start of drilling. The CNC-milled spiral groove optimally removes chips and allows for low-vibration and even drilling. Axial and radial relief grinding ensures maximum cutting performance and absolutely smooth results. The step drill is made of HSS steel and is exceptionally durable when using coolant. The clearly visible and permanent diameter markings in both spiral grooves are laser-etched. The HSS step drill creates smooth and burr-free holes of various diameters and is ideal for drilling and enlarging holes. It is suitable for thin materials made of non-ferrous metals, stainless steel, and plastics, as well as steel sheets and plastic panels.
