For the most demanding locksmithing tasks, the HSS-TiN step drill may be indispensable. This type of accessory for power tools is used to enlarge holes, mark drilling points, or chamfer internal edges. The product can be used with drills and screwdrivers equipped with cylindrical chucks. The STALCO PERFECT HSS-TiN step drill is useful for tough and professional tasks. It is made of high-speed steel (HSS) with a titanium nitride (TiN) coating, providing high wear resistance and allowing work with the hardest metals. During production, a spiral groove for chip removal and a cross grind at the tip are formed. The drill features laser-engraved measurements, making it very convenient to work with. Additionally, it leaves smooth edges inside the hole after drilling. STALCO offers three different drills to match holes of various diameters and depths.
