Ruko HSS R Twist Drill Bit for Steel and Metal with Reduced Shank, DIN 338, Type N, Black Finish, 18.0 mm Diameter, 191 Length, R200180

Ruko Din 338 Type N Hss Ø 18 Mm Metal Drill Bit. RUKO DIN 338 Type N HSS Metal Drill Bit | 18 mm | Reduced ShankAchieve precise, large-diameter holes in metal with the professional-grade RUKO DIN 338 Type N HSS Metal Drill Bit. This individual 18 mm drill bit is engineered for professionals and serious DIY enthusiasts who demand exceptional reliability and performance from their electric tool accessories. Specifically designed for drilling in metal, it combines robust construction with intelligent design to deliver superior results in demanding applications.This is a high-performance rolled, steam-treated twist drill meticulously crafted from heavy-duty high speed steel. The advanced steam treatment creates a microporous surface that improves lubricant adhesion and reduces material build-up, ensuring smoother cutting and significantly extending the tool´s operational life.At the core of its superior durability is an innovative manufacturing procedure. The unique rolling process solidifies the material without causing structural disruption, resulting in a drill bit that is significantly more elasticated. This enhanced elasticity provides exceptional resistance to fracture, even under the high torque and stress associated with robust drilling units. This makes it perfectly suitable for heavy-duty work with tools like powerful hand-held drilling machines, where lesser bits might fail.One of the standout features of this 18 mm drill bit is its incredible versatility. It is ideally suitable for drilling larger drilling diameters on all commonly-used drilling machines, even those with a standard clamping chuck up to 13.0 mm. This is made possible by the precision-machined reduced shank, which allows you to tackle ambitious projects requiring large-bore holes without needing specialized, large-chuck equipment.Engineered for precision, the bit features a Shape N helical point with a normal ground 118° point angle, ensuring excellent self-centering and efficient chip removal for clean, accurate holes. The right-hand cutting direction and normal flute profile are optimized for consistent performance across a variety of metalworking tasks. Choose the RUKO DIN 338 HSS drill bit for its superior fracture resistance, precision engineering, and unparalleled versatility. It is the ultimate individual metal drill bit for when performance and reliability cannot be compromised.Technical Specifications:* Diameter (Ø): 18.0 mm* Total Length (L1): 191.0 mm* Material: HSS-R (High-Speed Steel, Rolled)* 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* Weight: 0.255 kg. tradeinn Bricoinn
