Material-specific SC drill with three cutting edges for higher feed rates than with two-edged drills. Three spacious flutes for rapid chip evacuation. Three-margin lands deliver better hole quality and straightness than two-flute drills. TiAlN-coated KC7210™ grade for higher wear resistance at elevated speeds. Uncoated K10™ grade helps to prevent built-up edge in drilling aluminum and high-temp alloys.
