Sumitomo’s WDX indexable drills are designed for large diameter hole drilling. The accurately drill can also perform turning and boring operations, the company says. The drill’s nickel-plated steel body is said to reduce inventory costs by accepting the same insert geometry for both the outer and inner cutting edges and allowing the use of all four of the insert’s cutting edges.
The drills feature ZX-coated, carbide insert grades ACP300 and ACK300, and they can be used to machine a variety of steels, stainless steels, cast iron and exotic materials. The drills are available in coolant-through 2×D, 3×D and 4×D body lengths for multiple drilling applications.

All they need is speed! Tools for roughing nickel-based alloys can be used in the same processes as carbide tools, just with high rpm and no coolant.
