RUKO Din 345 Type N Hss Ø Wood 39.5 Mm 204395

RUKO DIN 345 Type N HSS Taper Shank Drill Bit 39.5 mm | MT4Experience unparalleled power and precision in your heavy-duty drilling operations with the RUKO DIN 345 Type N HSS Taper Shank Drill Bit. Expertly engineered for professionals in metalworking, fabrication, and industrial maintenance, this individual 39.5 mm drill bit delivers exceptional performance and reliability when tackling the most demanding materials. It stands as a benchmark for quality and durability in the electric tool accessories category, designed to integrate seamlessly with stationary machinery like drill presses, lathes, and milling machines.This is a highly efficient standard drill with a morse taper, purpose-built for high-torque applications. It is the definitive solution for drilling steel, cast steel, and cast iron – both alloyed and unalloyed. A key design focus is its robust construction, making it highly secure against fracture, ensuring operational safety and tool longevity even under significant stress. This resilience translates to reduced downtime and consistent, predictable results in critical industrial environments.The superior performance originates from its intelligent design features. The Morse Taper 4 (MT4) shank provides a rigid, self-locking connection directly into the machine spindle. This eliminates any chance of slippage, ensuring that all rotational power is transferred directly to the cutting edge for maximum efficiency and precision. The bit is precision-ground from high-quality high-speed steel (HSS-G), offering enhanced hardness, wear resistance, and thermal stability. The standard 118° point angle, combined with a Shape A cut chisel edge, allows for excellent centering and reduced thrust force, enabling smooth and accurate hole-starting.With a substantial total length of 349.0 mm and an impressive flute length of 200.0 mm, this tool is perfectly suited for deep-hole drilling applications up to 6 times its diameter. The standard Type N helix angle of 20-30° is optimized for efficient chip removal in ferrous metals, preventing clogging and heat build-up to maintain cutting performance throughout the operation. The bright surface finish and precise h8 tolerance further underscore its quality, contributing to cleaner holes and extended tool life. For any professional seeking a powerful, accurate, and incredibly durable drilling solution for large-diameter holes in metal, this RUKO drill bit is the ultimate choice.Specifications:- Diameter (Ø): 39.5 mm- Total length L1: 349.0 mm- Flute length L2: 200.0 mm- Material: HSS-G (High-Speed Steel, Ground)- Surface: Bright- Cutting direction: Right-hand cutting- Shank: Morse Taper 4 (MT4)- Drilling depth: 6 x D (6 times diameter)- Point cut: Shape A: Cut chisel edge- Point angle: 118°- Helix angle: 20-30°- Tolerance: h8- Weight: 1.65 kg
