Double-alloy thermal composite wear-resistant reamer tooth

The utility model discloses a double-alloy thermal composite wear-resistant reamer tooth which comprises a double-alloy wear-resistant reamer tooth body of a wedge-shaped structure. The reamer tooth body is sequentially provided with a solid tooth tip, a tooth handle and a sleeve which are connected into a whole from top to bottom; reinforcing ribs are arranged on the force bearing face from the tooth tip to the tooth handle, the sleeve is used for being arranged on the reamer head in a sleeving mode, and a fixed installation hole is formed in the side face, on the same side with the reinforcing ribs, of the sleeve in a penetrating mode. The reamer tooth has the advantages of being novel in design, reasonable in structure and capable of being installed on a reamer head for use, solving the problems that an original single metal is not resistant to abrasion, short in service time, frequent in replacement and capable of affecting construction yield, meanwhile solving the problems that a cold composite alloy com
