The D14×L65×D10×L20 solid carbide internal cooling twist drill, launched by AMG, is specially developed to meet the high-efficiency and high-precision drilling demands in the general machinery industry. Made from ultra-fine grain solid carbide (HM), this tool offers excellent wear resistance, fracture toughness, and thermal stability. Combined with internal cooling channels and optimized twist flute design, it achieves high chip evacuation and stable continuous machining even under complex conditions, widely used for deep hole drilling in various mechanical components.

Applications
Suitable for through holes, blind holes, and deep hole drilling of structural parts, housings, flanges, brackets, and other components in general machinery. It is ideal for machining carbon steel, alloy steel, stainless steel, cast iron, and other metal materials. Particularly suitable for applications requiring high hole perpendicularity and surface finish.

Specifications

Working Principle
During cutting, coolant is delivered directly to the cutting edge through internal channels to quickly reduce the tool temperature, preventing tool wear and workpiece surface burning. The twist flute design allows smooth chip evacuation, reducing the risk of tool breakage and hole accuracy loss caused by chip clogging, ensuring stable and efficient machining.
