Kyocera SGS Precision Tools has expanded its Z5 high-performance lineup of roughing tools to include 50 through-coolant items. 

The Z-Carb HPR five-flute roughing end mills are designed for high metal removal rates and finishes of 80 RMS or better on most materials. The specialized five-flute design is engineered for increased productivity compared to three- and four-flute end mills. The variable indexing geometry is said to improve chatter suppression compared to symmetrical designs. The new items are offered in ½" and 12-mm diameters. The through-coolant option delivers coolant to the cutting zone to enhance chip removal when pocketing and slotting.
