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.
Titanium nitride (TiN)-coated high-speed steel reamers handle a range of materials, running faster than uncoated reamers and lasting twice as long. The coating acts as a barrier against high temperatures and abrasion.
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.
Right-hand spirals pull chips upward as they cut, so they’re often used in blind holes.

Straight flutes are used for general purpose cutting. Since chips are forced forward into the hole, they perform best in through-hole applications. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Hole-Alignment Reamers
Straighten, enlarge, and deburr misaligned and overlapping holes. Also known as bridge, car, and aligning reamers, they have a tapered tip for easy entry into misaligned holes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
