The Subland Drill (2-2) eliminates secondary operations by drilling multi-diameter holes in one production pass. In certain applications particularly holes in steel or cast iron, the Subland Drill (2-2) provides superior tool life compared to that of a basic step drill.

Also called subland drill bits, these bits countersink as they drill to prepare holes for tapping. The 90° countersink angle guides the tap into the hole. The drill bit diameter will not change after sharpening. For technical drawings and 3-D models, click on a part number.
