Reamers Manufacturers

Reamers are rotary tools used for light material removal. Reamers are suitable for deburring and sizing the inside diameter (ID) of holes. Reamers are used for enlarging or finishing a hole previously drilled, bored, or cored to give a good finish and an accurate dimension. A typical reamer consists of a set of parallel straight or helical cutting edges along the length of a cylindrical body. Each cutting edge is ground at a slight angle and with a slight undercut below the cutting edge. Reamers must combine both hardness in the cutting edges, for long life, and toughness, so that tool does not fail under the normal forces of use. They should only be used to remove small amounts of material. This ensures a long life for the reamer and a superior finish to the hole.
