The D7.41xL23.8xD10xL105 solid HM internal coolant straight flute drill is a high-performance carbide drill bit developed by AMG specifically for high-precision deep hole machining in automotive components. Made from ultra-fine grain solid carbide (HM), this drill features excellent wear resistance, anti-chipping properties, and high thermal stability. Its straight flute geometry enhances guiding accuracy, while internal coolant channels significantly improve chip evacuation and cooling efficiency. This ensures long-lasting, stable performance under high-load, high-speed conditions in automotive manufacturing, improving hole consistency and overall machining efficiency.
Application
This drill is widely used in the machining of automotive parts such as engine blocks, transmission housings, hydraulic valve bodies, fuel injector seats, and brake system components—especially those requiring strict deep hole precision, verticality, and clean surface finishes. Suitable for machining structural materials commonly used in the automotive industry including steel, stainless steel, cast iron, and aluminum alloys.
