2.2500" Reamers | McMaster-Carr

Smooth the inside and edges of holes with these reamers. Often used to finish holes in sheet metal or to remove burrs from the ends of cut pipe and conduit, they're also known as repairmen's reamers.

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.

Arbor Mount, For Round Shanks


Reamer and Arbor (Sold Separately)	Straight Flute

Pair these reamers with a compatible arbor (sold separately) to mount to your drill press or other machine. This setup lets you ream larger holes than other shank types. They’re also known as shell reamers.

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.
