Not only are the faster penetration rates maintained, but in using the redesigned body of the T-A Pro, maximum coolant flow and excellent rigidity are also present when utilizing the high-speed steel geometry. This offers machine shops and manufacturers a spade drill that operates at incredible speeds and a cost per hole that averages 25% less than other existing drills.
