For holes of very precise size in steel, brass, aluminum, copper, plastic, or wood, reach for these Unibit high-speed stepped drill bits. They have laser-etched hole sizes that are permanent and easy to read. You can even use them to make holes of multiple sizes in thin materials without changing bits. Some Unibit high-speed stepped drill bits have anti-skid tips that eliminate the need for pilot holes.
