About Reamers
More
High-Speed Steel Round-Shank Reamers
The shank diameter is slightly smaller than the reamer diameter.
Titanium nitride (TiN) coated reamers run faster than uncoated reamers and last twice as long. The coating acts as a barrier against high temperatures and abrasion.
Straight-flute reamers are for general purpose cutting.
Spiral-flute reamers have a right-hand spiral and a right-hand cut. They pull chips upward as they cut, so they’re often used in blind holes. Spiral flutes create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut.

Inch Size Hand Reamers
Use a straight-handle tap wrench (sold separately) to turn these reamers by hand. The cutting end is slightly tapered to ease hole entry for the final sizing of drilled holes. Choose a straight-handle tap wrench that fits the diameter of your hand reamer.
Straight-flute reamers are for general purpose cutting.
Spiral-flute reamers have a left-hand spiral and a right-hand cut. They push chips downward as they cut, so they’re often used in through holes. Spiral flutes create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut.

Expansion Hand Reamers
Use an adjustable wrench or straight-handle tap wrench (sold separately) to turn these reamers by hand. When the reamer wears down, twist the set screw to expand the diameter, and then grind the reamer to its original size. The cutting end is slightly tapered to ease hole entry for the final sizing of drilled holes.
These reamers are not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The adjustment screw should never be loosened.
Straight-flute reamers are for general purpose cutting.
Spiral-flute reamers have a left-hand spiral and a right-hand cut. They push chips downward as they cut, so they’re often used in through holes. Spiral flutes create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut.

Round-Shank Drill Reamers
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 drill reamers 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.

Round-Shank Reamers for Hole Alignment with Safety Collar
A collar on the shank prevents you from reaming past the cutting edge. These reamers are for use with hand-held electric and air tools. Also known as bridge reamers, car reamers, and aligning reamers, they ream, true, enlarge, align, and debur holes. All have tapered ends for easy entry into misaligned holes. They are not for reaming tapered holes.
