    Jobbers' Length

    Image of Specification. Standard. Front orientation. Contains Border. Standard Point. For Metal.

    Standard

    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. High-speed steel is good for general purpose drilling in most metals. Also known as Silver and Deming bits.
    Jobbers' Length—These 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.

    Pipe and Conduit Drill Taps

    Image of Product. Front orientation. Drill Taps. Pipe and Conduit Drill Taps.
    Drill and thread holes for pipe and conduit without switching tools. Made of uncoated high-speed steel, these tools are for use on most metal and plastic. Their right-hand spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping of through holes.
