    Reamer Sets

    Keep a variety of reamer sizes on hand for finishing holes.
    Round Shank
    Image of Product. Front orientation. Reamers. Reamer Sets, 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.
    Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.
    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.

    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.

    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.
    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.
    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.

    Round-Shank Reamer Drill Bits

    Image of Product. Front orientation. Contains Annotated. Reamer Drill Bits. Round-Shank Reamer Drill Bits.
    Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these reamer drill bits are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as carbon fiber, fiberglass, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
