Turn these metric reamers by hand with a straight-handle tap wrench.

Inch Size Hand Reamers

Turn these inch size reamers by hand with a straight-handle tap wrench.

Morse Taper-Shank Reamers

The tapered shank fits the spindle hole of machine tools with a Morse taper.

Threaded-Shank Reamers

These reamers have a 1/4”-28 threaded shank.

Arbor-Mount Reamers

Smooth and expand hole diameters that are 1 ¾" and larger with these reamers.

Expansion Round-Shank Reamers

These reamers are designed for use in drill presses, turret lathes, screw machines, and other machine tools.

Expansion Hand Reamers

Use an adjustable wrench or straight-handle tap wrench to turn these reamers by hand.

Straight-Blade Adjustable-Size Reamers

Ream multiple hole sizes with one tool. Tighten or loosen the two nuts on these reamers to move the adjustable blades within the diameter range.

Angle-Blade Adjustable-Size Reamers

Often used on holes with keyways and other interrupted cuts.

Extra-Long Angle-Blade Adjustable-Size Reamers

A long, permanently mounted pilot steadied by a floating sleeve lets you align holes that are spaced far apart.

Round-Shank Drill Reamers

Drill and finish holes in a single pass with these dual-purpose tools.

Reamers for Hole Alignment

Hex Nut-Shank Reamers for Hole
Alignment with Safety Magnets

Magnets on the hex nut hold the reamer in place in your tool and prevent it from accidentally falling.

Hex Nut-Shank Reamers for Hole Alignment

The hex nut on the end of the shank lets you use these reamers with square-drive impact wrench sockets.

Round-Shank Reamers for Hole
Alignment with Safety Collar

A collar on the shank prevents you from reaming past the cutting edge.

Round-Shank Reamers for Hole Alignment

For use with hand-held electric and air tools, these ream, true, enlarge, align, and deburr holes.

Short-Length Round-Shank Reamers for Hole Alignment

Correct hole misalignment when working in confined spaces. About 2" shorter than standard hole-alignment reamers of similar thicknesses, these reamers give you extra room to move when there’s limited space between you and your workpiece.

Morse Taper-Shank Reamers for Hole Alignment

Use these reamers in stationary machines.

Reamers for Dowel Pins

Cobalt Steel Reamers for Dowel Pins

Better abrasion and heat resistance than high-speed steel for up to 25% faster cutting.

High-Speed Steel Reamers for Dowel Pins

For general purpose applications.

Carbide Reamers for Dowel Pins

Solid carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for the highest accuracy and longest tool life. These reamers retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive materials.
