Round-Shank Reamer for Hole Alignment

Manufacturer part: 3089A22

Enlarge holes to correct misalignment and overlap. Misaligned holes often have a narrow entry, so the tapered shape is easier to insert and makes more contact to remove the overlapping material. These are also known as bridge and car reamers.Round Shank—These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.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.
