Metric Size Drill-Point Counterbore Sets
No need for separate tools, these sets have counterbores in various sizes that drill and counterbore holes with enough clearance for socket head cap screws. The longer the counterbore, the thicker the material it can drill.

Hex-Shank Combination Drill Bit/Tap Sets for Drills and Screwdrivers
Drill and tap holes in a range of diameters. With a drill bit point to drive into the workpiece, these tools can drill and tap holes in a single step. Connect them directly to drills, power screwdrivers, and other tools that accept a 1/4" hex shank. They're made of high-speed steel and are for use on most metal and plastic. Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. Recommended for use in through holes, all have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
