The invention discloses a process method for producing a tool through a caulking groove substrate. The process method comprises the following steps of (1) substrate preparing, (2) substrate cleaning,(3) high-speed steel bar embedding, (4) vacuum welding, (5) tempering, (6) straightening, (7) accurate grinding, (8) blade planing, (9) long blank cutting, (10) blade accurate grinding, (11) tool cutting, (12), perforating, (13), straightening and (14) cleaning, rust prevention and finished product packaging. By means of the process, the machining steps and process are shortened, the machining difficulty is reduced, the machining efficiency is improved, the machining cost is saved, and the machining yield and the stability of quality and performance are improved.
