Tungsten Carbide Reamer Construction

A common tungsten carbide reamer construction includes a cylindrical body that consists a set of helical cutting edges along it. Specially,every cutting edge has a slight angle, and below which there ‘s a small undercut. It is recommended that the cutting edges of  reamer should have both hardness and toughness, so that ,during the usage, the tool could work functionally under the normal forces . 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.

For production machine tools, the shank type is usually one of the following: a standard taper , a straight round shank to be held by a collet, or a straight round shank with a flat for a set screw, to be held by a solid toolholder. For hand tools, the shank end is usually a square drive, intended for use with the same type of wrench used to turn a tap for the cutting of screw threads.
