    Reamers

    Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.
    Material
    • High-Speed SteelDurable and wear resistant, these are good for general purpose reaming in most materials.
    • Titanium Nitride (TiN) Coated High-Speed SteelCoated to create less friction than uncoated high-speed steel reamers, these run faster and last twice as long.
    • Cobalt SteelWith 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 SteelSince 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.
    • CarbideFor the highest level of accuracy when cutting hard materials, these are our hardest, strongest, and most wear-resistant reamers. They're used on materials such as iron, hardened steel, steel alloys, and plastic. Their hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the reamer from breaking.

    Round Shank
    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 FlutesSince 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.
    Morse Taper Shank
    These reamers work with machine tools that have a Morse taper spindle hole, such as a drill press or lathe.
    Square Shank
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench.
    Threaded Shank with Built-In Pilot
    These reamers fit power drills that have a 1/4"-28 threaded spindle or adapter. Using a powered hand tool can affect alignment, so these have a built-in pilot that guides the reamer into the hole and keeps it straight.
    Arbor Mount
    Reamer Shown Installed on Arbor (Sold Separately)
    Pair these reamers with a compatible arbor (sold separately) to mount to your drill press or other machine. This setup lets you ream larger holes than other shank types. They’re also known as shell reamers.

    Expansion Reamers

    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.
    Material
    • High-Speed SteelDurable and wear resistant, these are good for general purpose reaming in most materials.
    • Carbide-Tipped SteelSince 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.

    Round Shank
    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Square Shank
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench.

    Adjustable-Size Reamers

    Finish multiple hole sizes with one reamer by moving the adjustable blades within the diameter range. Convenient for maintenance work, these have large diameter range and don't require powered tools. They're often used to make precise size adjustments during installation of bearings and bushings.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Material
    • High-Speed SteelDurable and wear resistant, these are good for general purpose reaming in most materials.
    • SteelTypically more economical but less durable than high-speed steel, these are for general purpose reaming.
    Square Shank
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench.

    Hole-Alignment Reamers

    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.

    Round Shank
    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Round Shank with Safety Collar
    A collar on the shank prevents these reamers from going too deep into material, protecting your tool's chuck from damage. With a round shank, the most common shank type, they fit in the chuck of drill presses, turret lathes, and other machine and power tools.
    Morse Taper Shank
    These reamers work with machine tools that have a Morse taper spindle hole, such as a drill press or lathe.
    Hex Shank
    The shank fits hex impact sockets, so you can use an impact wrench to both ream the hole and install a fastener.
    Hex Shank with Safety Magnets
    These reamers have magnets on the hex nut to keep them from accidentally falling out of your tool. They fit hex impact sockets, so you can use an impact wrench to both ream the hole and install a fastener.

    Adjustable-Size Hole-Alignment Reamers

    One tool both finishes multiple diameters and enlarges holes to correct misalignment and overlap. Also known as bridge, and car reamers, they have a tapered shape that fits into the narrow entry of misaligned holes and makes more contact to remove the overlapping material. Change the reamer size by moving the adjustable blades within the diameter range.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Material
    • SteelTypically more economical but less durable than high-speed steel, these are for general purpose reaming.
    Square Shank with Built-In Pilot
    A built-in pilot guides and steadies these reamers through holes that are spaced far apart. Turn the reamer by hand with an adjustable wrench or straight-handle tap wrench.

    Deburring Reamers

    Smooth the inside and edges of holes with these reamers. Often used to finish holes in sheet metal or to remove burrs from the ends of cut pipe and conduit, they're also known as repairmen's reamers.

    T-Handle Shank
    No additional tools required, these reamers have an integrated handle that's easy to grip and turn.
    L-Handle Shank
    Turn these reamers with the long ratcheting handle, which provides more leverage than a T-handle.

    Taper-Pipe Reamers

    Use these reamers to shape and finish a hole to a tapered pipe size before tapping.

    Reamers for Dowel-Pin Holes

    Finish holes to match standard fractional dowel pin sizes. These reamers are undersized with a very slight taper to ensure dowel pins fit snugly when installed.
    Material
    • High-Speed SteelDurable and wear resistant, these are good for general purpose reaming in most materials.
    • Cobalt SteelWith 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.
    • CarbideFor the highest level of accuracy when cutting hard materials, these are our hardest, strongest, and most wear-resistant reamers. They're used on materials such as iron, hardened steel, steel alloys, and plastic. Their hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the reamer from breaking.
