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.

Round Shank

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.

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.

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.

Morse Taper Shank

Spiral Flute

These reamers work with machine tools that have a Morse taper-spindle hole, such as a drill press or lathe.

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.
