Drill America 1-39/64" HSS Reduced Shank Drill Bit - 3/4" Shank

Upgrade your toolkit with the Drill America DWDRSD Series reduced shank drill bit. Engineered from high-speed steel, this bit provides the perfect balance of hardness and toughness for general purpose applications. The 1-39/64" diameter is paired with a 3/4" shank, allowing you to expand the size range capacity of your portable drill chuck easily. Designed for efficiency, the bit features a 118 degree point and a black oxide finish. This specialized coating adds lubricity and creates small surface pockets that hold coolant near the cutting edge, helping to manage heat during operation. The spiral fluted design ensures that chips are evacuated up and out of the cut when running in a counterclockwise direction, which helps prevent clogging. Whether you are working with low or medium tensile strength materials, this precision-ground tool delivers high concentricity between the shank and body diameter. The common flute and overall length design minimizes the need for frequent adjustments during tool changes, making it a reliable choice for consistent drilling performance.
