Reamers for Taper-Pin Holes
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.
