DWDRSD1-1/4 1-1/4" Reduced Shank High Speed Steel Drill Bit with 1/2" Shank D...

Made of HS Steel and ground to a 118° point. These drills expand the

size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes. Precision ground for high degree of concentricity between shank and body diameter. Ideal for drilling in low and medium tensile strength materials. Black oxide finish.High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistanceBlack oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edgeRound shanks allow use with a wide variety of toolholding systemsWhen run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce cloggingIdeal for drilling in low and medium tensile strength materials
