Ingersoll introduces a 2-Start indexable carbide insert hob, which almost doubles productivity for machining gears with large numbers of teeth when compared with single-start ICI hobs. The hob features inserts with four cutting edges and simple setup with no shims or adjustment required. The segmented design provides an expandable assembly and simplifies repair. The company can be designed for rough, pre-grind and finish applications depending on the gear quality requirement.
