Our S&D drills are designed to drill the holes with big size. The unified shank diameter permits the different drills to be installed into the same tool holder. The S&D applies the same process as the taper shank drills. They are ground or milled and the surface is very smooth. The material can be HSS and HSSCO. The surface can be black, bright, black&bright, golden, black&golden.
