Kennametal Inc.'s Beyond Blast inserts channel coolant through the insert to the milling cutter/insert interface. This delivers coolant directly where the tool cuts the material to provide more efficient coolant delivery, heat transfer and lubricity, the company reports. The inserts are available for turning and milling applications. When turning titanium, Kennametal conducted tests using 100-psi coolant delivery and showed a 75 percent improvement in tool life compared to the same inserts with 100-psi flood coolant.
