Ruko Din 338 Type N Ø 4.5 Mm Metal Drill Bit. RUKO DiN 338 Type N Ø 4.5 mm Metal Drill Bit - High-Performance Tungsten CarbideCategory: Electric tool accessoriesSubcategory: Drill bitsUnlock superior drilling precision and power with the RUKO DiN 338 Type N Ø 4.5 mm Metal Drill Bit. Engineered in Germany for the most demanding applications, this individual drill bit is the definitive choice for professionals and craftsmen seeking exceptional performance and longevity when working with metal. Its robust construction and advanced design make it a versatile and indispensable tool for any workshop.Exceptional Performance on Tough MaterialsThis is a high-performance twist drill with brazed-on HM cutting inserts made from K20 fine grained material. It is suited for universal applications and for high-strength steel. Its specialized geometry and material strength allow it to effortlessly penetrate challenging surfaces, delivering clean, accurate holes every time. Continuous cooling is required when drilling into high-strength steel to maintain optimal performance and bit integrity. Furthermore, this bit is highly recommended for machining cast iron, a material where its durability and cutting efficiency truly excel, providing smooth operation and a superior finish.Advanced Design for Precision and EfficiencyThe RUKO DiN 338 features a Shape C split point, a self-centering design that prevents the bit from walking on the material surface. This eliminates the need for pre-punching or pilot drilling, saving you time and ensuring pinpoint accuracy from the very start. The 120° point angle provides an aggressive yet controlled cut, while the 25-30° helix angle ensures smooth and efficient chip evacuation, preventing clogging and overheating for a cleaner workflow. The right-hand cutting direction and cylindrical shank make it compatible with all standard drill chucks.Engineered with an h8 tolerance, this 4.5 mm drill bit guarantees a precise hole diameter, critical for applications requiring tight fits and secure fastenings. Its construction allows for a substantial drilling depth of up to 5 times its diameter, offering excellent versatility for both thin sheet metal and thicker stock. Whether you are in fabrication, automotive repair, or general maintenance, this high-performance metal drill bit delivers the reliability and precision your projects demand.Technical Specifications:* Diameter (Ø): 4.5 mm* Total Length (L1): 80.0 mm* Flute Length (L2): 47.0 mm* Material: Tungsten Carbide* 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: 0.00700 KG. tradeinn Bricoinn
