Dormer A218 Set #1-5 Bright High Speed Steel 90 Degree Combined Drill & Countersink 5 Piece 0423929

A 5pc set of the Dormer A218 series high-speed steel combined drill and countersink. Kit comes with 1 each of #1, #2, #3, #4, #5. Each tool 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.
