Smooth drilling of holes with various diameters is possible with the HSS step drill TiN. The drill produces smooth and burr-free holes without the need for center punching, as the cross-ground tip facilitates the start of drilling. The CNC-milled spiral groove optimally removes chips and allows for low-vibration and consistent drilling. Axial and radial relief grinding ensures maximum cutting performance and absolutely smooth results. The drill is made of HSS steel and is coated with TiN (Titanium Nitride), which significantly extends its lifespan when using coolant. The clearly visible and durable diameter markings in both spiral grooves are laser-etched. The 3-flat shank prevents slipping in the chuck and allows for the transfer of high torque. The HSS step drill is ideally suited for drilling and enlarging holes in thin materials made of non-ferrous metals, stainless steel, sheet metal, and plastic.
