    Reamers
    3D CAD models available

    Finish holes to precise inch, metric, wire gauge, or letter sizes with these 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.
    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—For 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.
    Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.

    Straight Flute

    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.

    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.
    Hex Shank

    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.
    Secure Hold—Magnets on the shank’s end keep these reamers from accidentally falling out of your tool.

    Jobbers' Length—The same length as jobbers' drill bits, these reamers save setup time when you want to drill and ream on the same machine, such as a drill press or bench lathe.
