High Guidance Internal Coolant Carbide Drill Bit Cutting Tool Accurate Hole Positioning

The Solid HM Internal Coolant Straight Flute Drill is a high-performance carbide cutting tool developed and manufactured by AMG. Specifically designed for high-precision, high-efficiency deep hole machining applications, this tool features an ultra-fine grain solid HM (hard metal/carbide) substrate. It offers excellent wear resistance, fracture toughness, and thermal stability. The combination of straight flute geometry and advanced internal coolant channels ensures optimal chip evacuation, precise guidance, and significantly improved drilling stability and hole quality.

Perfectly suited for high-precision deep hole drilling in aerospace, medical device manufacturing, automotive components, and mold making. It is especially effective for machining difficult-to-cut materials such as stainless steel, titanium alloys, and heat-resistant superalloys.

The tool employs a straight flute design to ensure superior axial guidance and drilling stability. Integrated internal coolant channels deliver cutting fluid directly to the cutting edge, significantly reducing heat buildup and tool temperature, thus preventing thermal deformation and extending tool life. The internal cooling system also minimizes thermal stress and built-up edge during cutting, ensuring smooth chip evacuation and enhancing hole wall finish and positional accuracy—crucial in precision deep hole drilling tasks.
