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.

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.

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.

• High wear resistance for extended tool life
• Precision drilling accuracy for quality results
• Efficient chip removal for continuous operation
• Internal cooling system for temperature control
• Compatible with various metal materials
• Widely used in metal structures, machinery manufacturing, and automotive maintenance

India currently represents the largest market for alloy steel twist drills due to rapid manufacturing and infrastructure development. Southeast Asia, particularly Vietnam and Thailand, shows significant growth potential for these precision tools.
