The CoroDrill 862 are solid carbide micro drills, equipped with specially customized point geometry that minimizes thrust forces. It is made up of a thin, and effective covering that aids in maintaining cutting edge geometry while providing a smooth surface for chip evacuation. It is best applied in steel, stainless steel, aluminum and cast iron tool geometries and surface treatments.

The CoroDrill 862 has a shank diameter of 0.118 inches throughout the range, and an achievable high tolerance of H8-H9. It is utilized with CoroChuck 930 high precision chucks. Furthermore, it contains internal coolant holes which render coolant directly to the tip of the drill even at deep drilling depths.
