We would, of course, be remiss if we didn't mention milwaukee 21 core set for daily usage. The Milwaukee Thunderbolt Black Oxide drill bits are designed for extreme durability and long life. It features a thicker core than a standard drill bit to provide ultimate strength and protect against side-load breakage. The quarter inch bit will fit in hole saw chucks as well, and the set screw seats in the bevel. It is good for moderate use.

These bits will serve their purpose in the tool kit for general purposes of drilling pilot holes or drilling holes in projects that need a hole to be drilled. A great feature that sets these apart from most bits, is the bevels on the top of the shaft.
