Zusammenfassung:The invention discloses a novel auxiliary cutting wear-resistant pickaxe-shaped cutting pick which comprises a pick head assembly and a twist drill tool set. A hard alloy head is mounted on the tooth head assembly; a plurality of spiral grooves are formed in the outer wall of the tooth head assembly in the circumferential direction at equal intervals. The multiple twist drill tool sets are installed on the side wall of the tooth head assembly in the circumferential direction, and the twist drill tool sets are rotationally connected with the side wall of the tooth head assembly. The twist drill cutter group is made of a wear-resistant material; the multiple twist drill tool sets and the multiple spiral grooves are arranged in a one-to-one correspondence mode, and the twist drill tool sets are located on guide lines of the spiral grooves. The spiral groove is formed in the pick head assembly, so that the light weight of the pickaxe-shaped cutting pick is achieved, and the effect of assisting in cutting is achie
