With reduced heat generation, tool life is greatly extended.
Coolant is induced without being run through expensive machine spindles.
This eliminates premature bearing failure and body wear. As a result, there is no friction from any seals which causes body wear. Since the wear causing seals do not contact the Hi-Jet Holder body, contaminants and their subsequent friction damage will be limited to the Merit Set and only these parts would need to be replaced. This is quite an advantage over replacing the entire worn body or scrapping the entire unit altogether.
