Reamers - Nomenclature and Definitions

A Reamer is used to finish a pre-drilled hole to a high degree of accuracy and surface finish. It does this by removing a minimum amount of metal from the sides of the hole whilst being rotated in the same direction as a twist drill at a much slower speed than that used for drilling. However, the spiral flutes of a Reamer .
