For trouble-free machining and close hole tolerances of IT6, CoroBore® 826 utilizes high-precision nozzle to direct coolant jet to cutting edge, efficiently controlling and breaking chips which are then evacuated from hole. Stepwise scale setting of tool diameter optimizes process security and eliminates setting mistakes, while rigid interfaces between head and cartridge ensure stable and vibration-free boring. CoroBore 826 HP meets fine boring requirements from 1.417–49.606 in.
