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 heat stability. The combination of straight flute and advanced internal coolant channels ensures chip evacuation, precise guidance, and significantly improved drilling stability and hole quality. This tool is ideal for tackling the challenges posed by aerospace-grade metals.
Applications
Perfectly suited for high-precision deep hole drilling in aerospace, medical device manufacturing, and mold making. It is especially effective for machining difficult-to-cut materials such as stainless steel, titanium alloys, and heat-resistant superalloys.
Specification Table
| Diameter (D) | Overall Length (L) | Flute Length (L1) | Shank Diameter (d) | Coolant Type | Material |
|---|---|---|---|---|---|
| 3.0 mm | 75 mm | 20 mm | 6 mm | Dual Internal Coolant | Ultra-fine Grain HM |
| 5.0 mm | 100 mm | 30 mm | 6 mm | Dual Internal Coolant | Ultra-fine Grain HM |

Working Principle
The tool uses a straight flute design to ensure superior axial guidance and drilling stability. Integrated internal coolant channels deliver cutting fluid directly to the cutting edge, then reducing heat buildup and tool temperature, and preventing heat deformation and extending tool life. The internal cooling system also minimizes heat 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.
