    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 taps are for use on most metal and plastic. With a square shank, they’re compatible with tap wrenches and tap holders for drill presses and milling machines. These taps have a plug chamfer with 3-5 chamfered cutting threads, so they’re suitable for start-to-finish tapping of through holes.
    Spiral Flute—Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.

    Impact Wrench Pipe and Conduit Taps

    Cut threads inside pipe and conduit 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, these taps are built to handle the high torque of impact wrenches to cut material quickly. Your wrench’s rapid hammering keeps these taps moving forward for smooth, continuous cutting. Those rapid blows also help break and clear chips as you cut, so you don’t need to pause and reverse, even in large holes and tough materials. This also means the tap is less likely to jam on chips and snap.
    You’ll need a VersaDrive chuck (sold separately) to install these taps into your impact wrench. You can also get chucks for impact drivers (sold separately).

    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.
