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 |
| 8.0 mm | 120 mm | 45 mm | 8 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.
