RUKO Hss-co 5 Short Din 1897 Type N Serie 202 12mm Drill Set 5 Pieces A1166111212R202120E

RUKO HSS-Co 5 Short DIN 1897 Type N Serie 202 12mm Drill SetCategory: Electric tool accessoriesSubcategory: Drill bitsMaster your most demanding metal drilling tasks with the RUKO HSS-Co 5 Short DIN 1897 Serie 202 12mm Drill Set. Engineered for professionals who require uncompromising precision, stability, and longevity, this premium drill bit set is the definitive choice for working with a wide range of tough metals. Its specialized design and superior construction ensure optimal performance where standard drill bits fall short, providing clean, accurate results in challenging industrial, fabrication, and maintenance environments.Unmatched Stability and Breakage ResistanceThe core benefit of this RUKO drill bit set is its exceptionally short and stable design, manufactured to the rigorous DIN 1897 standard. This robust construction dramatically increases rigidity and provides high resistance to breakage, making it the perfect tool for drilling into thin materials such as steel sheet, where longer bits are prone to wandering, flexing, or snapping. Experience superior control and confidence, knowing your drill bit can handle high-stress applications without failure. This inherent stability ensures perfectly perpendicular holes and a safer drilling experience.Precision Engineering for Flawless PerformanceAchieve pinpoint accuracy from the very start. Each 12 mm drill bit in this set features a precision point grinding with a split point according to DIN 1412 C. This advanced self-centering tip immediately bites into the material, eliminating the frustrating walking effect on smooth or curved surfaces. This means no need for a preliminary center punch, saving you time and guaranteeing that your hole is drilled exactly where you intend it. Combined with a right-hand cut and a 135º cutting angle, this design ensures aggressive, efficient drilling with reduced feed pressure and excellent chip evacuation.Superior Durability for Hardened MetalsThis is not just any metal drill bit set. It is a short and stable standard drill bit made of high-performance high-speed steel and cobalt alloy, giving it a significantly higher thermal hardening resistance. This allows the cutting edge to stay sharp and effective even at the extreme temperatures generated when drilling dense and abrasive materials. It is the ideal solution for drilling into stainless steel and other high-alloy steels, delivering extended tool life and consistent performance where other bits would quickly dull and fail.Versatile ApplicationsEngineered for versatility, this set is your go-to solution for a vast array of materials. It is perfectly suited for alloyed and unalloyed steel (up to a strength of approx. 900 N/mm²), cast iron, malleable cast iron, and high-alloy chromium steels such as V2A/V4A stainless steel, as well as acid and rust-resistant steels. Whether you are in a machine shop, an automotive garage, or on a construction site, this drill set provides the reliability you need. The
