RUKO HSS DIN 338 Type N 11.5 mm Drill Bit Set - Precision Ground for Metal & MoreElevate your drilling capabilities with the RUKO HSS DIN 338 Type N Serie 214 11.5 mm drill bit set. Engineered in Germany for professionals and serious enthusiasts who demand uncompromising precision and performance, this 5-piece set is the ultimate solution for a wide range of metalworking and fabrication tasks. Whether you are in a professional workshop or tackling a demanding project at home, these drill bits deliver consistent, clean, and accurate results every time.This high-performance ground standard twist drill is made from heavy-duty high-speed steel (HSS). The fully ground twist drill has a precise concentricity, which is critical for creating perfectly round and dimensionally accurate holes. Thanks to the split point, this drill has good centring properties and requires little pressure. This innovative tip design prevents the bit from walking on the material surface, allowing for an immediate and precise start without the need for a centre punch, saving you time and reducing user fatigue.Designed for optimal efficiency, these 11.5 mm drill bits are built to withstand the rigours of drilling into tough materials. The robust HSS construction ensures excellent heat resistance and a long service life, even under demanding conditions. Adhering to the strict DIN 338 standard, each drill bit guarantees dimensional accuracy and interchangeability, fitting securely into any standard cylindrical shank chuck. The Type N flute design with a normal groove profile ensures efficient chip evacuation, keeping the cutting area clear and preventing overheating for a smoother drilling process and a superior finish on your workpiece.Primary Application:This drill bit set excels in general-purpose drilling across a variety of common industrial and workshop materials.
