Drill America 31.00mm Reduced Shank High Speed Steel Bit with 1/2" Shank, DWDRSD Series

HSS tools are perfect for most general applications, offering a combination of hardness and toughness for wear resistance Black oxide treatment adds lubrication and creates small pockets on the tool surface that act to hold coolant near the sharp edge Round shanks allow use with a wide variety of tool holding systems When used counterclockwise (right-hand cut), spiral fluted tools drain chips up and out of the cut to reduce clogging Ideal for drilling low and medium tensile strength materials
