    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.

    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.

    Impact Wrench Reamers for Hole Alignment

    Driven by the high torque of an impact wrench, these reamers enlarge holes to correct misalignment and overlap faster than with a power drill. The tapered shape fits into narrow holes and makes more contact than straight reamers when removing material. Also known as bridge and car reamers.
    Hex Shank
    The shank fits hex impact sockets, so you can use an impact wrench to both ream the hole and install a fastener.
    Helix Flute—Prevent clogging when removing excess material with helix flutes. They also leave a smoother finish than straight flutes.
    Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.
    Strong Hold—Magnets on the shank’s end keep these reamers from accidentally falling out of your tool.
