DIAcooling
Effective supply of liquid to the cutting edge, even with tools without internal coolant: a nozzle ring in the nut, matched to the shank diameter, keeps the coolant stream close to the tool at both low and high speeds.

TECHNICAL INFORMATION
Cooling efficiency that increases with cutting speed
As speed increases, standard solutions lose coolant flow and turn into a spray. DIACOOLING generates a substantial coolant flow precisely directed toward the cutting edge: tool life extended by up to two times, better surface finish of the workpiece and fewer burrs on the milled component.
