Choosing a rod with an internal coolant hole offers significant performance and economic advantages:
Dramatically Increased Tool Life: Heat is the number one enemy of cutting tools. By effectively managing temperature, the carbide rod retains its hardness and wear resistance for much longer, reducing the frequency of tool changes and downtime.
Higher Productivity: With better heat and chip management, you can safely use more aggressive machining parameters, such as higher cutting speeds and feed rates. This leads to faster cycle times and increased output.
Improved Part Quality: Consistent cooling and efficient chip evacuation result in better surface finishes, tighter tolerance control, and reduced burrs. This leads to higher-quality parts and fewer rejects.
Enhanced Process Reliability: The reduction in chip clogging and heat-related failures makes the machining process more predictable and reliable, which is crucial for unattended or automated manufacturing cells.
