Spiral Flute Hand Reamers, Fractional
- Hand reamers are made of high-speed steel and are generally used by hand for the final sizing of holes
- The square on the shank is suitable for holding in a tap wrench or a vise depending on whether the reamer or the part is rotated
- A long starting taper is ground into the reamer for easy entry and accurate alignment
- The straight-flute hand reamer is recommended for most hand reaming applications
- The spiral-flute hand reamer is recommended for applications where there is an interrupted cut such as a keyway
