KnKut KK12SP-9/16 Step-Point Drill, 1/2-Inch Shank
KnKut KK12SP-9/16 is the nine-sixteenths-inch fixed-diameter option with a half-inch reduced shank. Its cutting diameter is one sixteenth larger than the shank, making the two measurements easy to confuse when ordering by a chuck size instead of the required hole.
