YG-1 DH2231160

The YG-1 DH223 series comprises high-quality, general-purpose solid carbide drills designed for efficient and economical drilling across a range of materials.These drills feature a 3×D stub-length design without through-coolant holes, making them ideal for applications in steel (up to 38 HRC), cast iron, stainless steel, and even hardened steels up to 55 HRC.Key design elements include a self-centering point with special thinning, a negative land and wave-pattern cutting edge for reduced thrust and stable torque, and optimized flute geometry for smooth chip evacuation and enhanced drilling strength.The TiAlN coating further improves wear resistance and thermal stability, extending tool life in dry or semi-dry cutting conditions.Available in diameters ranging from 3.0 mm to 20.0 mm, the DH223 series is a versatile solution for CNC and general machining operations where reliability and cost-effectiveness are essential.
