Kennametal launches new Y-TECH drill
The Y-TECH drill is a new product from Kennametal and its unique geometry is designed to produce high quality holes in duplex stainless steels, titanium alloys, Inconel nickel based alloys and other difficult materials. The Y-TECH drill has three belts and the distance between the flutes is not equal. The traditional 2-blade drill has two belts and is symmetrical. The drill bit is prone to yaw when cutting into the workpiece. The asymmetric design of the Y-TECH drill allows the drill to maintain a constant diameter throughout the drilling process. Eliminating the yaw not only improves the quality of the hole, but also significantly reduces tool wear and extends tool life.
