Cobalt Silver & Deming

Our Silver and Demings bits are manufactured to our specificatins from M-35 Cobalt High Speed Steel. For a sure grip in the drill chuck, we use a 1/2" Round Shank with Tri-Cut shank flats.

Heavy-duty 118 point is recommended for use in drilling hard tough metals, free machining stainless steel, high temperature alloys, titanium and certain plastics.

Cobalt Silver and Deming drill bits require rigidly held, positive feed drilling equipment for best results.
