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

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.
