Reduced-Shank Drill Bits
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.
High-Speed Steel Jobbers' Length

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.
3-Flat Shank—Three flat sides on the shank prevent the bit from slipping in the chuck of a drill press or portable drill.
Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
