Drill America 31.00mm HSS Drill Bit - 1/2 inch Shank

Upgrade your tool kit with the Drill America DWDRSD Series high speed steel drill bit. Designed for versatility, this 31.00mm bit features a reduced 1/2 inch shank, allowing you to expand the size range capacity of your portable drill chuck. This makes it an essential component for users needing larger hole diameters without switching to heavy machinery. Built for performance, the bit is precision ground to ensure high concentricity between the shaft and body diameter. This precision reduces vibration and improves drilling accuracy. The 118 degree point design and spiral fluted edges work together to drain chips up and out of the cut, which helps prevent clogging during operation. Each bit features a black oxide finish that provides extra lubrication and creates small surface pockets to hold coolant near the cutting edge. This construction makes it ideal for drilling into materials with low to medium tensile strength. Whether for general applications or specific workshop tasks, this HSS tool offers the hardness and toughness required for reliable wear resistance.
