RUKO DIN 340 TL 3000 HSS-Co 5 Metal Drill Bit, 4.25 mm - Precision for Deep DrillingUnleash professional-grade drilling performance with the RUKO DIN 340 TL 3000 HSS-Co 5 Metal Drill Bit. Specifically engineered for demanding applications, this 4.25 mm long-series drill bit is the ultimate solution for precision deep drilling in a wide range of challenging materials. Whether you are a professional metalworker, an industrial fabricator, or a serious DIY enthusiast, this bit delivers unparalleled durability, accuracy, and efficiency where standard drill bits fail. Its robust design and advanced features make it a must-have accessory for any high-stakes drilling task.Exceptional Durability and Heat ResistanceCrafted from a high-performance special cobalt alloy high-speed steel (HSS-Co 5), this drill bit features significantly higher thermal tempering resistance. This ensures a longer service life and consistent performance, even when drilling at high speeds or into the toughest metals. This superior composition allows the bit to maintain its cutting edge sharpness under extreme thermal stress, reducing wear and maximizing productivity on the job.Optimized for Deep and Difficult DrillingAs a DIN 340 long-series bit, it is particularly suitable for deep drilling applications. Its unique 40º helix angle provides an aggressive cutting action and excellent chip evacuation, preventing clogging and overheating in deep holes and with difficult-to-chip materials. This specialized geometry ensures a smooth, continuous cutting process, which is critical for achieving clean and accurate holes in thick workpieces.Precision Self-Centering StartFeaturing a conical point grinding with a split point according to DIN 1412 C, this bit eliminates the need for pre-punching or center marking. The 130º point angle ensures an immediate, precise centering and a fast, wander-free start on both flat and curved surfaces. This feature saves valuable time and guarantees a higher degree of accuracy from the very beginning of the drilling process. Each individual drill bit is engineered for this flawless start.Broad Application Range for Demanding MaterialsThis is not just a standard metal drill bit, it´s a versatile workhorse. Engineered to cover types N, H, and W broadly, it excels in drilling alloyed and unalloyed steels (up to a strength of approx. 1200 N/mm²). Its capabilities extend to the most challenging materials found in modern industry.Ideal for Materials Including:* High-Alloy Chromium Steels such as V2A and V4A* Acid and Rust-Resistant Steels* Titanium and Titanium Alloys* Cast Iron* Aluminum and Aluminum Alloys* Copper, Brass, and Bronze* And other materials.The distinct golden brown surface is a hallmark of its high-quality tempering process, a visual indicator of the bit´s inherent strength and resilience. These drill bits are supplied in a convenient, translucent plastic case with a red background label for easy identification and secure storage.Technical
