    Reamer Type

    Shank Type

    Reamers for Hole Alignment

    Enlarge holes to correct misalignment and overlap. Misaligned holes often have a narrow entry, so the tapered shape is easier to insert and makes more contact to remove the overlapping material. These are also known as bridge and car reamers.

    Spiral Flute

    Depth Limiting

    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    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.
    Depth Limiting—A collar on the shank prevents these reamers from going too deep into material, protecting your tool's chuck from damage.
    Short Length—About 2" shorter than standard-length reamers of similar thicknesses, these give you room to maneuver in tight spaces.

    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    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.
    Cobalt Steel—With better heat and wear resistance than high-speed steel, these reamers run up to 25% faster, last longer, and perform better on hard materials, such as cast iron, hardened steel, titanium, and stainless steel.
    Carbide-Tipped Tool Steel—Since these reamers retain a sharper, harder edge at higher temperatures than high-speed steel and cobalt steel, they can be used on hard materials, such as iron, hardened steel, and steel alloys. They aren't as brittle as solid carbide reamers, so they can be used in less rigid setups, such as a hand-held drill.
    Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

    Straight Flute

    Unlike standard reamers, which are unusable once they become worn, these can be returned to their original size for finishing holes. After the reamer is worn down, tighten the set screw to expand the diameter, grind the reamer to its original size, and get back to work.
    These are not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The set screw should not be loosened.
    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.

    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
    Image of Product. Front orientation. Contains Annotated. Reamers. Impact Wrench Reamers for Hole Alignment, Hex Shank, Spiral Flute.

    Spiral Flute

    The shank fits hex impact sockets, so you can use an impact wrench to both ream the hole and install a fastener.
    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.

    Driven by the high torque of an impact wrench, the reamers in these sets enlarge holes of various diameters 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.
    VersaDrive Hex Shank
    All VersaDrive tools have the same hex shank, so you need only one chuck (sold separately) to fit them into your impact wrench. This lets you quickly switch from your reamer to a drill bit, tap, or any other cutting tool you need to complete the next job. For jobs that don’t require the torque of an impact tool, you can also fit these reamers directly into a 1/2" chuck on a standard power drill.
    Do not use these reamers on holes that were flame or plasma cut.
    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.
    Titanium Nitride (TiN)-Coated Hardened High-Speed Steel—Coated to create less friction than uncoated high-speed steel reamers, these run faster and last twice as long. They’re also hardened for increased wear resistance, making them good for cutting hard metals.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

    Strong-Hold

    These chucks mount directly onto the square drive of your impact wrench. They work with any tool with a VersaDrive hex shank, so you don’t need to swap chucks to use drill bits, taps, and other tools.
    While impact wrenches give you the most torque of any power tool, we also have chucks for impact drivers and magnetic-base drills if you want to use other tools.
    Quick-Change Pull-Back Tool Release—Require just one hand to load. Push your tool in the chuck until you hear the ball detents click into place. To remove your tool, pull back the collar.
    Strong-Hold Push-Forward Tool Release—Hold cutting tools more securely than quick-change chucks. To insert and remove cutting tools, you must push a collar forward. Since impact force drives your cutting tool the opposite way, it can’t come loose from the chuck while you work.
    Manganese Phosphate-Coated Steel—The coating on these chucks prevents rust.
