Reduced-Shank Drill Bit Sets
Cut large holes with drill presses and portable drills that have a standard-size chuck. The shank on these bits has a smaller diameter than the cutting tip. Also known as Silver and Deming bits.

Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.
Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
