Dormer A218 #2 Bright High Speed Steel 90 Degree Combined Drill & Countersink 5/64 0239308

The Dormer A218 series high-speed steel combined drill and countersink has an uncoated (bright) finish, has a plain style to create a pilot hole with a 90-degree countersink that accepts a flat-head fastener so it sits flush with the surface, and meets United States Cutting Tool Institute (USCTI) standards. The 118-degree conventional point drills a center hole, while the two spiral flutes clear chips away to prevent clogging. High-speed steel (HSS) provides hardness for wear resistance, and the uncoated finish has no additional surface treatment or coating. The tool is double-ended to provide two cutting ends. The round shank accommodates most drill chucks.
