About Reamers
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. There are many types of reamers. Examples include a hand reamer, ridge reamer, tapered reamer, bushing reamer, pipe reamer and a drill reamer. A hand reamer has a longer taper or lead-in at the front than a machine reamer. A ridge reamer is used in engine cylinders for movement of a piston. A tapered reamer is used for cleaning burrs from a drilled hole or to enlarge a hole. A bushing reamer can easily adjust to cut the exact ID dimension required for a tight barrel-to-bushing fit. A pipe reamer has a self-feeding spiral design for extra-fast and easy hand reaming. A drill reamer is used in drilling applications. Other reamers are commonly available.
