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 maintains 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.
It is suitable for aluminum alloys, cast iron, compacted graphite iron (CGI), and steel engine blocks.
TiAlN provides excellent thermal stability and reduces friction, extending tool life during high-speed and dry or MQL machining.
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.
