Hex-Shank Masonry Drill Bit Sets for Impact Drivers
The 1/4" hex shank allows these bits to be used with standard impact drivers. Instead of using a hammering action to break up masonry material, theys drill with rotary action only, requiring more pressure to grind up material.

Drill/Mill End Mill Sets
These multifunction tools have a 90° pointed tip that allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. Made of solid carbide, they're harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
