For deep-hole drilling, the company offers the Helios 15D and 20D cobalt HSS drills. The drills can process deep holes without the use of an internal coolant supply and without pecking. The flute design improves chip evacuation, making it feasible to drill as much as 20 × D without pecking. Patented thinning decreases thrust. The company says its WXL coating enables the drills to accommodate a range of materials with as much as three times greater wear resistance versus conventional coatings.
