Ruko Din333/hss Ø 5 Mm Center Drill Bit. RUKO DIN 333 / HSS Ø 5 mm Center Drill Bit: The Foundation for Precision MetalworkingAchieve unparalleled accuracy and a professional start to all your drilling and turning projects with the RUKO DIN 333 / HSS Ø 5 mm Center Drill Bit. As a crucial component in any serious machinist´s or metalworker´s collection of electric tool accessories, this individual drill bit is engineered to create perfectly concentric and dimensionally accurate center holes in a wide variety of metal workpieces. Designed for professionals who demand reliability and precision, this bit eliminates the common issue of drill walking, ensuring that every subsequent drilling or turning operation is perfectly aligned from the very beginning.Key Benefits:* Flawless Starting Accuracy: Say goodbye to wandering drill bits. The specialized geometry of this center drill creates a perfect conical guide, ensuring your main drill bit engages the material exactly where intended. This is the first and most critical step for achieving tight tolerances and professional-grade results in your metal projects.* Enhanced Workpiece Stability: Specifically designed for making centre holes according to shape A, this bit creates the ideal seat for lathe centers. This provides robust and stable support for your workpiece during turning operations, minimizing vibration and chatter, which leads to a superior surface finish and dimensional accuracy.* Superior Durability and Longevity: Constructed from premium High-Speed Steel (HSS-G), this bit is ground from a solid blank for maximum precision and structural integrity. It offers excellent hardness and heat resistance, allowing for consistent performance and a long service life even when working with tough materials.* Versatile Application: Whether you are using a drill press, a milling machine, or preparing a workpiece on a lathe, this 5 mm center drill is an indispensable tool. It is expertly suited for creating starting points in steel, cast iron, sintered metals, and non-ferrous metals, making it a versatile addition to any workshop.Main Features:This RUKO center drill bit is defined by its purpose-built design and high-quality manufacturing. Its primary function is to execute the combined drilling and countersinking action needed to produce a DIN 333 Shape A center hole. The bit features precision-ground flutes that provide sharp cutting edges and facilitate efficient chip removal for a clean and smooth cut. The bright surface finish is ideal for general-purpose applications, preventing material adhesion and ensuring a clean cutting process. Its robust cylindrical shank guarantees a secure and concentric grip in all standard drill chucks, translating to stable and precise performance.This individual drill bit is the go-to choice for machinists, engineers, and fabricators who understand that the precision of the final product is determined by the quality of its foundation.Technical Specifications:* Standard: DIN 333* Hole Profile: Shape A* Pilot Diameter (d1): 5.0 mm* Body Diameter (d2): 12.5 mm* Total Length (L1): 63.0 mm* Material: HSS-G (Ground High-Speed Steel)* Surface: Bright* Shank: Cylindrical* Point Angle: 120°* Countersink Angle: 60°. tradeinn Bricoinn
