The D19 × L80 × D20 × L135 hard alloy internally cooled straight groove drill bit
launched by AMG company is a high-performance drilling tool
designed to meet customers' needs for high-precision and high
directional deep hole machining. This drill bit solves several key
issues in the procurement process, such as aperture accuracy,
machining stability, tool life, and compatibility with various
materials. Through optimized structural design and high-quality
materials, this drill bit ensures continuous, stable, and
high-quality deep hole drilling in harsh industrial applications.
The drill bit is made of ultra-fine solid hard alloy (HM), which
has excellent wear resistance and thermal stability. The straight
groove design enhances directional control, while the double internal cooling channels can directly deliver high-pressure
coolant to the cutting edge. This effectively reduces cutting
temperature, improves chip removal efficiency, and ensures
excellent aperture quality, making it particularly suitable for
applications that require high precision and reliability.
Applications
Ideal for deep hole machining in industries such as energy
equipment, mechanical engineering, mold manufacturing, hydraulic
systems, and aerospace. Suitable for drilling stainless steel,
alloy steel, titanium alloys, and heat-resistant alloys—especially
in complex or deep cavity components .

Working Principle
The high-precision straight-flute design ensures strong guidance
during drilling, reduce deflection and hole deviation. Both
internal coolant system delivers coolant directly to the cutting
edge, rapidly dissipating heat, reducing thermal deformation, and
preventing built-up edge formation. The coolant channels also
enhance chip evacuation, preventing clogging and maintaining a
clean, smooth hole surface.
Key Advantages
Excellent Guidance: Straight-flute design improves stability and
hole accuracy.
Use for High-Strength Materials: Performs keep well on titanium
alloys, stainless steel, and superalloys.
Superior Toughness: Solid carbide body and ultra-fine grain
structure ensure durability and resistance to breakage.
Customizable by AMG: Non-standard dimensions and flute designs
available per customer requirements.
