    Rebar-Cutting Core Drill Bits for Concrete

    Core out large holes in concrete, even if it's reinforced with rebar mesh. No need to switch bits, these have a diamond-coated edge that keeps on cutting and resists wear to stay sharp.
    Threaded-Hub Shank for Rotary Only Drilling
    Image of Product. Front orientation. Drill Bits. Rebar-Cutting Core Drill Bits for Concrete, Threaded-Hub Shank for Rotary Only Drilling.
    Bits are designed for wet drilling on a drilling rig. To avoid damage to bits and tools, do not use for dry drilling or with portable drills or grinders.

    These cutters are perfectly sized for cutting holes that will be tapped later. Use them with magnetic-base drills. Unlike drill bits, these cut only on the periphery of the hole and produce a solid slug. They're also known as annular cutters.
    Hollow-Core Cutter Pilot Pins—Pilot pins align the cutter and eject the slug. They're also known as ejector pins.

    Straight Flute

    Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with 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.
    Uncoated High-Speed Steel—Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.

    Quick-Change Hex Shank Drill Taps for Drills and Screwdrivers

    Image of Product. Front orientation. Drill Taps. Quick-Change Hex Shank Drill Taps for Drills and Screwdrivers.
    Save time when you need to change drill taps frequently. The grooved shank snaps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. However, they’re not rated for impact drivers. With a drill bit point to drive into the workpiece, these taps can drill and tap holes in a single step. They’re made of high-speed steel and are for use on most metal and plastic.
    Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. All have a plug chamfer with 3-5 chamfered cutting threads, so they’re suitable for start-to-finish tapping.
    Uncoated High-Speed Steel—Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.
    Titanium Nitride (TiN)-Coated High-Speed Steel—Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.

    What you need to add or repair threads quickly in parts under stress or vibration. These inserts come with a closed-end tap, a drill bit, and an installation bit. Also known as E-Z Lok, they have Loctite® adhesive already applied, and the adhesive reaches full strength after 72 hours.
    Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than standard and extra-thick wall inserts for applications with strict weight limits.
    Black Phosphate-Coated Steel—These inserts resist occasional moisture.

    Drill Chucks with NMTB Taper Integral Arbor

    Image of Product. Top orientation. Drill Chucks. Drill Chucks with NMTB Taper Integral Arbor.
    Limit runout and slippage under heavy cutting forces from manual mills and older CNC mills. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ASME standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick change spindles. Internal threads in the shank connect to your machine's drawbar.
    Twist the sleeve by hand to swap bits out quickly. The grip on the bit tightens as torque increases.
    To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

    Chuck

    Reduce runout and slippage under heavy cutting forces from CNC machines. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. Their shank is precision ground to the industry standard AT3 tolerance for a tight fit in your spindle. They meet ASME standards for compatibility across machines with CAT spindles. They have a threaded hole that accepts retention knobs, so they connect to your machine’s drawbar system. For automatic tool identification and tracking, these chucks have a hole for a small RFID tag.
    To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.
    Keyless Chuck—Keyless chucks let you swap bits in and out with a quick twist of the sleeve. As torque increases, their grip will tighten. These chucks only tighten in the clockwise direction, so they may loosen under heavy reverse loads, such as during left-hand drilling. They’re balanced to grade 6.3, so they’re good for most drilling tasks.
    Keyed Chuck—Keyed chucks use a worm-and-gear design to deliver exceptional grip on bits for the highest torque and accuracy when drilling in hard materials. They're so strong they can even be used for light duty milling in soft materials such as aluminum. Use their Torx key to tighten and loosen the chuck. Balanced to grade 2.5, they vibrate 60% less than chucks balanced to 6.3 for longer life under heavy use and high speeds. You can route coolant through these chucks to extend the life of your bit and clear chips.
