Working Principle
The AMG TiAlN-coated carbide through-coolant drill uses high-speed rotation and optimized chip evacuation while coolant passes internally through the drill to the cutting edge. This ensures effective heat dissipation and lubrication, prevents thermal deformation, and remain consistent hole quality during deep hole drilling in engine blocks. The TiAlN coating reduces friction and oxidation at high temperatures, while the precision-ground geometry enhances centering and drilling stability.
Advantages:
✅ Extended Tool Life: TiAlN coating offers superior heat and wear resistance during high-speed drilling.
✅ Efficient Chip Evacuation: Through-coolant design prevents chip packing and breakage in deep hole drilling.
✅ High Stability: AMG’s precision manufacturing ensures excellent concentricity for high-accuracy holes.
✅ Smooth Bore Finish: Offer low roughness and clean hole surfaces, reducing the need for additional honing.
FAQ
1. What materials can this drill handle?
It is suitable for aluminum alloys, cast iron, compacted graphite iron (CGI), and steel engine blocks.
2.Why is the TiAlN coating beneficial?
TiAlN provides excellent thermal stability and reduces friction, extending tool life during high-speed and dry or MQL machining.
3. What is the recommended cutting speed?
Typical speeds are 60-150 m/min for cast iron and 150-300 m/min for aluminum alloys, depending on the coolant system and machine rigidity.
