The i-Center, a trademark of Nine9 and the world’s first patented indexable center drill, offers exceptional precision and convenience. It delivers excellent repeatability with a radial accuracy of 0.02 mm (0.0008") and axial positional accuracy of 0.05 mm (0.002"). High-pressure coolant can be supplied directly through the center to the tip of the drill insert, enhancing performance and tool life. The i-Center is available in four forms DIN 332 Form R, DIN 332 Form A+B, DIN 332 Form A, and ANSI 60° to suit various machining standards. Additionally, tool length re-setting is unnecessary during tool changeovers, significantly reducing setup time and improving overall efficiency.
