RUKO Din 338 Type N Ø 7 Mm Metal 815070

RUKO DiN 338 Type N Metal Drill Bit Ø 7 mm | High-Performance Tungsten CarbideAchieve unparalleled precision and performance in your metalworking projects with the RUKO DiN 338 Type N Ø 7 mm Metal Drill Bit. Engineered for professionals and demanding craftsmen, this drill bit is the ultimate solution for drilling tough and abrasive materials with exceptional accuracy and efficiency. Its robust design and advanced features make it a reliable and indispensable accessory for any electric drill, suitable for use in both stationary machines and handheld power tools.This high-performance twist drill stands apart due to its expertly brazed-on HM (Hard Metal) cutting inserts, which are crafted from a premium K20 fine-grained material. This construction delivers outstanding hardness and heat resistance, allowing the bit to maintain a sharp, effective cutting edge for a significantly longer service life, even when tackling challenging jobs. It is perfectly suited for universal applications across a wide range of metals and is specifically designed to excel when drilling high-strength steel. For optimal performance and tool longevity when working with high-strength steels, the application of continuous cooling is required. Furthermore, this drill bit is highly recommended for machining cast iron, where its durability and cutting power provide clean, precise holes with minimal effort.The geometry of the RUKO DiN 338 Type N is optimized for superior drilling performance. The precision-ground split point (Shape C) according to DiN 1412 C ensures immediate, excellent self-centering upon contact with the workpiece. This critical feature prevents the bit from walking or wandering, eliminating the need for pre-punching or pilot drilling and enabling a faster, more accurate start to every hole. The standard 120° point angle, combined with a 25-30° helix angle, provides an ideal balance of aggressive cutting and efficient chip evacuation for clean, consistent results. The bright surface finish and cylindrical shank ensure smooth operation and compatibility with all standard drill chucks. Manufactured to a tight h8 tolerance, this drill bit guarantees dimensional accuracy for applications where precision is paramount.Key Attributes:* Diameter: 7 mm* Application: Metal---Technical Specifications:* Ø (Diameter): 7.0 mm* Total length L1: 109.0 mm* Flute length L2: 69.0 mm* Material: Tungsten carbide* Surface: bright* Cutting direction: right hand cutting* Shank: cylindrical* Drilling depth: 5 x D (35 mm)* Point cut: Shape C: Split point* Point angle: 120°* Helix angle: 25-30°* Tolerance: h8* Weight: 0.02200 Kg
