Reamers
Enlarge holes to exact inch, metric, wire gauge, or letter sizes. Reamers also smooth the walls of holes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

The most common shank type, it fits in the chuck of drill presses, turret lathes, and other machine and power tools. Also known as chucking reamers.
Use high-speed steel reamers for general purpose reaming on a wide variety of materials.
Cobalt steel reamers offer better heat and abrasion resistance than high-speed steel reamers to run up to 25% faster for a longer tool life. They're commonly used on hard-to-machine materials such as nickel alloys, stainless steel, and titanium.
Carbide reamers are harder, stronger, and more wear resistant than carbide-tipped reamers for the highest accuracy. Use on hard and abrasive materials such as cast iron, nonferrous alloys, plastic, and hardened steel. Not for use with hand-held tools, they require rigid tool holding to prevent breakage.

Taper-Pipe Reamers
Size and shape a hole to a tapered pipe size prior to tapping, ensuring a tight fit when joining threaded components. These reamers create a taper and leave a smooth finish. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

These reamers have a square portion at the end of the shank so they can be turned by hand with an adjustable wrench or straight-handle tap wrench.
Use high-speed steel reamers for general purpose reaming on a wide variety of materials.
Left-hand spirals push chips downward as they cut, so they’re often used in through holes.

Drill-Length Reamer Sets
Shorter than standard-length reamers for rigidity, these can be used in the same tools as jobbers' drill bits to size and smooth holes. Sets include a variety of reamer sizes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
