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.

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

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.

Round Shank

Helix 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.

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.
