RUKO Hss-co 5 Din 338 Type N Serie 215 11mm Drill Set 5 Pieces A1166111201R215110

RUKO HSS-Co 5 DIN 338 Type N 11 mm Metal Drill Bit SetExperience superior drilling performance with the RUKO HSS-Co 5 DIN 338 11 mm metal drill bit set, the professional's choice for precision and durability in the most demanding applications. This set is engineered for those who require flawless results when working with tough and challenging materials. A robust, right-hand-cutting high-performance drill bit with excellent resistance to heat treatment. It is ideal for drilling high-strength, rust, acid and heat-resistant steel, delivering reliability and a long service life.Engineered for Extreme PerformanceAt the heart of this tool´s exceptional capability is its material. Crafted from premium HSS-Co 5, a high-performance high-speed steel with 5% cobalt content, this drill bit offers an incredible combination of high toughness and heat resistance. This composition makes it perfectly suited for drilling in difficult-to-machine materials with a tensile strength of up to 1100 N/mm², where standard drill bits would fail. The added cobalt significantly increases the bit´s red hardness, allowing it to maintain a sharp cutting edge even at the high temperatures generated when drilling dense metals.Precision from Start to FinishAchieve unparalleled accuracy with every hole. The advanced point geometry features a 130° point angle and a Shape C split point. This design ensures immediate self-centering upon contact with the workpiece, eliminating the frustrating walking or skidding that can occur on smooth or curved surfaces. The split point allows for aggressive and precise starting without the need for a center punch, saving valuable time and ensuring your holes are placed exactly where you need them. The optimized 36° spiral angle works in tandem with the normal groove profile for highly efficient chip evacuation, preventing clogging, reducing friction, and promoting cooler, faster drilling.Robust Design for Industrial UseBuilt to withstand the rigors of professional use, this drill bit features a thickened core for enhanced stability and fracture resistance, especially under high feed rates and torque. The cylindrical shank is manufactured to a tight h8 tolerance, ensuring a secure, concentric fit in your drill chuck for maximum power transfer and minimal run-out. This meticulous engineering, compliant with the DIN 338 standard, guarantees consistent quality and performance you can depend on for every job.Versatile Application RangeWhile designed for the toughest jobs, this drill bit set demonstrates remarkable versatility across a wide spectrum of materials.Main Application:* High-Strength Steel (up to 900 N/mm²)* Extra High-Strength Steel (up to 1.100 N/mm²)* Stainless Steel (V2A/V4A)* Aluminium* Brass* PlasticsOther Application:* Bronze* Cast IronChoose the RUKO HSS-Co 5 11 mm drill bit set for your electric tool accessories when you need uncompromising performance, precision, and longevity for all your metal drilling projects.Technical
