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.
