Ingersoll recently introduced a 2-Start Indexable Carbide Insert Hob, which nearly doubles productivity for machining gears with large numbers of teeth when compared to single-start ICI hobs. The Ingersoll 2-Start Hob features inserts with four cutting edges, and simple set-up with no shims or adjustment required. The unique segmented design provides an expandable assembly, and simplifies repair. Ingersoll's 2-Start Hob can be designed for rough, pre-grind and finish applications depending on the gear quality requirement.
