The main advantage of the STNWKA-19 drill bits is their production technology – they are hot-rolled, which increases their flexibility and resistance to breakage, which is crucial when working in difficult workshop conditions. Thanks to the use of a cylindrical shank, the drill bits are compatible with most hand drills, bench drills, and screwdrivers equipped with a keyless or keyed chuck available on the market.
Precisely ground cutting edges allow for fast and clean chip removal, which minimizes the risk of overheating the material and the tool itself. The set is delivered in a solid metal or plastic organizer, which not only protects the drill bits from mechanical damage and corrosion but also allows for instant finding of the required size thanks to clear markings.
By investing in this set, you gain the certainty that your assembly, service, or hobby work will be performed with the utmost care. These drill bits handle materials such as alloy and carbon steel, gray cast iron, sintered metals, or hard plastics perfectly. It is an essential piece of equipment for every technical service, ensuring work continuity without worrying about the tools dulling quickly.
