Ruko Tungsten Carbide Twist Drill Bit with Brazed on Cutting Insert, DIN 338, Type N, Bright Finish, 4.0 mm Diameter, 75.0 Length, R815040

Ruko Din 338 Type N Ø 4 Mm Metal Drill Bit. RUKO DiN 338 Type N Ø 4 mm Metal Drill BitAchieve unparalleled precision and efficiency in your metalworking applications with the RUKO DIN 338 Type N 4 mm Metal Drill Bit. Designed for professionals and serious DIY enthusiasts who demand uncompromising quality, this high-performance twist drill bit is engineered to deliver exceptional results in a wide range of materials, from general-purpose use to the most challenging high-strength steels and cast iron. This individual 4 mm drill bit is the ultimate solution for your metal drilling needs, offering superior durability and accuracy.Unmatched Performance in Tough MaterialsThis is a high-performance twist drill with brazed-on HM cutting inserts made from K20 fine grained material. The integration of tungsten carbide cutting edges provides extreme hardness and wear resistance, allowing you to drill through tough materials with remarkable ease and a significantly extended tool life compared to standard HSS bits. It is suited for universal applications and for high-strength steel. For optimal performance and to maintain the integrity of the bit when working with high-strength steel, continuous cooling is required. Furthermore, this drill bit is highly recommended for machining cast iron, where its robust construction ensures clean, consistent holes without premature wear.Engineered for Precision and Ease of UseThe RUKO DIN 338 Type N drill bit features a precisely ground Shape C split point with a 120° point angle. This advanced design offers a critical advantage: it is self-centering. This means the bit starts drilling immediately upon contact with the workpiece, eliminating the frustrating walking or wandering common with other bits. This feature removes the need for pre-punching or creating a pilot divot, saving you time and guaranteeing a perfectly placed hole every time. The cylindrical shank ensures universal compatibility with all standard drill chucks, making it a versatile addition to any toolkit. With a right-hand cutting direction and a normal flute profile, it provides excellent chip evacuation, reducing heat build-up and ensuring a smooth, clean drilling process from start to finish.Technical Specifications:* Diameter (Ø): 4.0 mm* Total Length (L1): 75.0 mm* Flute Length (L2): 43.0 mm* Standard: DIN 338* Material: Tungsten Carbide* Surface: Bright* Cutting Direction: Right-hand cutting* Shank: Cylindrical* Drilling Depth: 5 x D* Point Cut: Shape C: Split point* Point Angle: 120°* Helix Angle: 25-30°* Tolerance: h8* Profile of Flute: Normal* Core: Normal* Weight: 0.00500 KG. tradeinn Bricoinn
