Reamers

Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.

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.

Reamers for Taper-Pin Holes

Shape holes to match the profile of taper pins. After drilling a hole that matches the size of the small end of the taper pin you want to install, use these reamers to taper and finish the hole.

Square Shank

Straight Flute

Turn these reamers by hand with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately).

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.

High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
