RUKO 200155 Broca helicoidal DIN 338 tipo N HSS, laminada con mango reducido (Ø 15,5 mm)

Ruko Din 338 Type N Hss Ø 15.5 Mm Metal Drill Bit. RUKO DIN 338 Type N HSS 15.5 mm Metal Drill Bit | High-Performance DrillingUnlock superior drilling performance for your demanding metalwork projects with the RUKO DIN 338 Type N HSS Metal Drill Bit. As a leading choice in the electric tool accessories category, this individual 15.5 mm drill bit is specifically engineered for professionals and serious DIY enthusiasts who require precision, durability, and efficiency when working with metal. Whether you are fabricating, repairing, or assembling, this high-performance twist drill bit is designed to deliver clean, accurate holes with exceptional reliability.Engineered for superior durability and flexibility, this is a high-performance rolled, steam-treated twist drill made from heavy-duty high-speed steel. Its unique rolled manufacturing procedure is a key advantage, as it ensures the material´s grain structure remains intact (no structural disruption). This advanced process solidifies the material, making it more elasticated and robust. The direct benefit for you is a drill bit that is remarkably resistant to fracture, even under high torque and stress. This makes it the perfect, reliable companion for robust drilling units, including powerful hand-held drilling machines where consistency and safety are paramount.One of the standout features of this 15.5 mm drill bit is its versatility. It is ideally suitable for drilling larger drilling diameters on all commonly-used drilling machines, thanks to its intelligently designed reduced shank. This allows the bit to be securely held in any standard clamping chuck up to 13.0 mm, meaning you can achieve large-diameter holes without needing a specialised, large-capacity drill. This feature significantly expands the capability of your existing tools, making it a cost-effective and practical addition to your drill bits collection.The bit's geometry is optimized for effective performance in metal. The 118° point angle, combined with a Shape N helical point normal ground, provides excellent self-centering capabilities, reducing the risk of walking on the material surface and ensuring a precise start every time. The 25-30° helix angle facilitates efficient chip removal, preventing clogging and overheating to maintain a consistent cutting speed and prolong the life of the bit. Manufactured to the precise DIN 338 standard and featuring a right-hand cutting direction, this tool guarantees predictable and professional results. The steam-treated black surface not only gives it a distinctive finish but also enhances wear resistance and improves lubricant adhesion for smoother operation.Attributes: 15.5 mm, Individual, Metal Specifications:* Ø: 15.5 mm* Total length L1: 178.0 mm* DIN: 338* Material: HSS-R* Cutting direction: right hand cutting* Shank: reduced* Drilling depth: 5 x D* Point cut: Shape N: Helical point normal ground* Point angle: 118°* Helix angle: 25-30°* Tolerance: h8* Profile of flute: normal* Core: normal. tradeinn Bricoinn
