1.High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
2.No center punch is needed—the aggressive 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander".
3.All are manufactured with 1/4-28 UNF threads and 5/16" wrenching flats.
4.Adapted threaded hex shank drills for use in right-angle drilling heads when operating in confined spaces
5.Oxide coating prevents chip building, galling and welding on the workpiece. It is commonly used on low-carbon metals, stainless steel and ferrous metals.
