Reamers
Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.
Round Shank
 |
Straight Flute |
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.
Oversized Fractional—Oversized reamers are larger than the fraction by 0.001" in diameter to create a looser fit than standard sizes. They're typically used in holes where objects such as pins need to stay in place, but still can be easily removed.
High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.

Reamers for Taper Pipe
Use these reamers to shape and finish a hole to a tapered pipe size before tapping.
Square Shank

Spiral Flute |
Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
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.
