The VariDrill from WIDIA (Latrobe, PA) is a new multi-application drill engineered to deliver acceptable hole finish and extended tool life across a wide range of materials. VariDrill features an advanced point geometry and “marginless” design that reduces chipping on the tool’s edge and stabilizes cutting forces. The VariDrill point and flute design enables chips to roll smoothly and evacuate easily, resulting in noticeably less friction, heat, jamming, and scratching. Minimizing these drilling issues means users can expect an optimum surface finish with every hole across a wide range of work materials without fear of catastrophic failure due to chip jamming.
