Drill America 31.00mm Reduced Shank High Speed Steel Drill 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

Made of HS steel and ground to a point of 118°. These drill bits expand the size range capacity of a portable drill chuck. Common flute and total length for minimal adjustment during tool changes. Precision ground for a high degree of concentricity between shaft and body diameter. Ideal for drilling in low and medium tensile strength materials. Black Oxide Finish
