Manufacturers, especially job shops, know better than most the pressures of ever-increasing customer demands and the equally demanding requirements to control costs. Multi-purpose tools have been one method many shops use to bridge the gap. WIDIA’s (Fort Mill, SC) VariTap's design engineering includes a proprietary spiral point geometry that lowers tapping torque, extending tool life while efficiently driving chips forward in through holes. Optimized spiral flute geometry additionally aids chip evacuation, reducing bird-nesting in blind holes. Significant investment in WIDIA´s production process includes state-of-the-art CNC tool-grinders with robot loading system and advanced coating center that, combined with VariTap´s high vanadium HSS-E blanks, greatly improves wear resistance, explains the company. VariTap also can be used with all styles of tap holders including tension/compression holders, rigid holders, and synchronous tap holders.
