Straight Flute | Spiral 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.
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.

No additional tools required, these reamers have an integrated handle that's easy to grip and turn.

L-Handle Shank
 |  |
Straight Flute | Spiral Flute |
Turn these reamers with the long ratcheting handle, which provides more leverage than a T-handle.
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.
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.
Hardened Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.
Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.
Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

Deburring Scraper Drill Attachments for Pipe and Tube Edges
 |
These drill attachments scrape both the inner and outer edges of plastic pipe and tube to finish them for connections. There’s a hex shank on each end—flip attachments around in your drill to switch from deburring inside edges to outside edges. Use in drills 14V and up.

Round-Shank Reamer Drill Bits
 |
Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these reamer drill bits are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as carbon fiber, fiberglass, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
