The Sandvik Coromant (Fair Lawn, NJ) solid carbide micro drills offer outstanding performance for holes from 0.073 inches to 0.116 inches in diameter, according to the company. The CoroDrill 862 has a thin TiAlN coating to help retain cutting edge geometry and provide a smooth surface for chip evacuation. The CoroDrill 862 also provides good hole entry and exit, and achievable hole tolerance of IT8-IT9. Internal coolant holes deliver coolant directly to the tip of the drill, even at deep drilling depths, to further assist precision and chip removal. Available in drill lengths of 8-12 x D, the drills are only for use with HydroGrip® high precision chucks from Sandvik Coromant.
