How to Choose the Best Reamers

Types of Reamers

  • Hand Reamers: These are operated manually and offer excellent control for fine adjustments. They are ideal for deburring and minor enlargements.
  • Machine Reamers: Designed for use with power tools like drills or milling machines, these are built for high-volume work and faster material removal.
  • Specialty Reamers: This category includes reamers designed for specific tasks, such as pipe reamers for plumbing or chucking reamers for precision hole finishing.

Material and Size

  • Material: Reamers are typically made from high-speed steel (HSS) for durability and heat resistance, or carbide for extreme hardness and wear resistance, especially for hard metals.
  • Size: The size of the reamer refers to the diameter of the hole it can enlarge. Ensure the reamer's size range matches your project's requirements. Consider the tolerance needed for the finished hole.

Flute Design

  • Straight Flutes: Provide a clean cut and are suitable for most general-purpose applications.
  • Spiral Flutes: Offer a smoother cutting action and are better for producing accurate holes, especially in softer materials or when chip evacuation is a concern.

Frequently Asked Questions

What is the primary purpose of a reamer?
A reamer's main function is to enlarge an existing hole to a precise dimension and to smooth the internal surface. They are used to improve hole accuracy, remove burrs, and achieve a clean, finished edge.
How do I choose the correct size reamer?
Select a reamer whose diameter closely matches the desired final hole size. It's important to choose a reamer that is slightly larger than the existing hole but not larger than the target diameter. Check the specifications for exact sizing.
What is the difference between a hand reamer and a machine reamer?
Hand reamers are designed to be turned by hand, offering precise control for finishing tasks. Machine reamers are intended for use with power tools and are designed for faster material removal and higher production rates.
Can reamers be used on materials other than metal?
Yes, reamers can be used on various materials including wood, plastic, and composites. The type of reamer and its material composition should be chosen based on the hardness and characteristics of the material being worked on.
