Champion’s 1705C cobalt screw machine drills are referred to as “stub drills”. They are made from heat-restistant premium cobalt high speed steel and are for use in screw machine operations. The short flute and overall length increase their rigidity, resulting in better hole accuracy and extended tool life. Recommended for the drilling of high tensile materials like stainless steel, titanium, manganese steel, armor plating, and inconel.
