Kennametal's Latest Holemaking Innovation "Rebalances" Typical Assumptions of Solid Carbide Drilling

All drills walk. Although this condition is typically associated with applications using HSS drills, out-of-round holes, deflection, and poor cylindricity are, to a lesser degree, also the result of drilling with a solid-carbide drill. The same forces that cause the drill to “walk” or “push off” also reduce drill life. This is particularly true when drilling tough, exotic, and expensive aerospace and energy materials such as Inconel, Waspalloy, and duplex stainless steel workpieces. Wear quickly accelerates into chipping and then catastrophic drill failure within one or two holes of occurrence, resulting in machine downtime and longer lead time for critical aerospace or energy parts.

Due to high material, labor, and machine costs, aerospace, energy, and other major industries are demanding drills that guarantee process security, consistent new and reconditioned drill life, and excellent hole quality. Addressing these market demands is the new Y-TECH drill from Kennametal that “rebalances” traditional technical assumptions of drilling with a solid-carbide drill due to its unique design that features two asymmetrically angled cutting edges and three margins.
