RUKO Tc Din 338 Type N Ø 9 Mm Metal 814090

RUKO TC DIN 338 Type N Ø 9 mm Metal Drill Bit – Precision Drilling in Hardened MetalsExperience unparalleled drilling performance with the RUKO TC DIN 338 Type N Metal Drill Bit. Engineered for professionals and demanding enthusiasts who require ultimate precision and durability, this 9 mm individual drill bit is the definitive solution for your most challenging metalworking projects. This is a high performance solid carbide K 20 twist drill, especially well suited for high strength steels at high cutting speeds, delivering clean, accurate holes where standard bits fail.Built for exceptional strength and a long service life, this bit is crafted from premium tungsten carbide, allowing it to effortlessly penetrate the toughest materials. It is the ideal choice for drilling into high-strength alloyed and unalloyed steels, cast iron, and other hard metals, maintaining its cutting edge sharpness and structural integrity under extreme thermal and mechanical stress.Achieve flawless accuracy from the very first rotation. The bit features a precision-ground Shape C split point with a 118° angle, which enables excellent self-centering capabilities. This advanced tip design eliminates the need for a pilot hole or center punching, preventing the bit from walking across the workpiece surface and ensuring your holes are drilled exactly where you intend them to be. The result is a clean, burr-free entry and a perfectly positioned hole every time.Efficiency is at the core of its design. The right-hand cutting direction combined with a normal flute profile and a 20-30° helix angle ensures optimal chip evacuation. This superior chip flow reduces heat buildup and friction, allowing for higher cutting speeds and deeper drilling up to 5 times the diameter (5 x D) without compromising performance or tool life. The standard core provides the perfect balance of rigidity and chip removal capacity for a wide range of metal drilling applications.With a standard cylindrical shank and a strict h8 tolerance, this RUKO metal drill bit guarantees a secure, slip-free fit in all common drill chucks and delivers consistently accurate hole dimensions. Conforming to the DIN 338 standard, it represents the pinnacle of German engineering for reliable, repeatable, and high-quality results in any professional workshop or industrial setting.Technical Specifications:- Ø: 9.0 mm- Total length L1: 125.0 mm- Flute length L2: 81.0 mm- DIN: 338- Material: Tungsten carbide- Cutting direction: right hand cutting- Shank: cylindrical- Drilling depth: 5 x D- Point cut: Shape C: Split point- Point angle: 118°- Helix angle: 20-30°- Tolerance: h8- Profile of flute: normal- Core: normal
