In precision deep hole machining of mechanical and hydraulic
components, the accuracy, rigidity, chip removal ability, and
cooling efficiency of the tools are important .AMG hard alloy internally cooled deep hole drills are designed
specifically to meet these high-performance standards. Made of
ultra-fine particle hard alloy (HM), this tool combines advanced
internal cooling channels and optimized straight or spiral groove
geometry to provide efficient solutions for deep and micro hole
drilling of precision components.
Applications
AMG solid HM internal coolant deep hole drills are suitable for:
Oil channels, valve bores, and distribution holes in hydraulic
systems
Deep and high aspect-ratio hole drilling in precision mechanical
components
Efficient drilling of small and deep holes in industrial automation
assemblies
Fine hole machining on CNC machining centers or 5-axis machines
Through-hole machining in valve blocks, pump bodies, and hydraulic
manifolds
Specification Table (Example)
| Model | Material | Coolant Type | Length-to-Diameter Ratio (L/D) | Diameter Range | Coating Options | Compatible Equipment |
|---|
| AMG-HY10 | Ultra-fine grain carbide | Internal (single channel) | 5D / 10D | Φ2mm–Φ16mm | TiAlN / Uncoated | CNC machining centers, special machines |
Working Principle
Driven by high-speed CNC spindle, the AMG solid HM deep hole drill
feeds axially into the workpiece material. The internal coolant
channel delivers cutting fluid directly to the drill tip, rapidly
dissipating heat and lubricating the cutting edge. The flute
geometry ensures fast chip evacuation, preventing clogging and hole
damage. Even in 15D–20D drilling depths, this tool maintains
excellent machining accuracy and chip flow stability.
The selling point that customers are most concerned about as follow :
High precision: Customers usually focus on whether the drill bit
can provide high-precision hole position and aperture control,
especially in deep hole machining, where the flatness of the hole
bottom and consistency of the aperture are improtant.
Tool life and durability: Due to the fact that deep hole machining typically
requires long-term high load operation, customers hope that tool
can work stably for a long time. Choosing hard alloy drill bits
with strong wear resistance and high temperature resistance can
greatly reduce the frequency of tool replacement.
Cooling efficiency: The design of internal cooling channels is one
of the key selling points that customers are concerned about.
Effective cooling can reduce the temperature in the cutting area,
improve chip removal efficiency, prevent tool overheating and
damage, and maintain efficient cutting.
Customization requirements: For some special industries, customers
may need to customize according to specific processing requirements
to ensure that drill bit meets aperture, depth, or other special
process requirements.
FAQ
Q: Can this tool eliminate chip clogging in deep hole drilling?
A: Yes. AMG adopts dual internal coolant channel and
high-efficiency flute design, ensuring smooth chip removal and
minimizing clogging risks.
Q: Does it meet the strict verticality requirements for hydraulic
components?
A: Absolutely. The solid carbide construction provides outstanding
rigidity, and the specialized cutting geometry ensures high
coaxiality and minimal runout.
Q: Can it drill through quenched or high-strength alloy steels?
A: Yes. AMG offers coatings such as TiAlN and DLC, which provide
excellent heat resistance and are suitable for hardened or
high-strength materials.
