The invention relates to the technical field of well drilling devices, in particular to a drilling tool stabilizer and a drilling tool. The stabilizer comprises a vertically-arranged main body pipe, and at least two mounting grooves extending in the vertical direction are formed in the outer wall of the main body pipe; a stabilizing wheel assembly is mounted in one mounting groove, and a cutting block is mounted in the other mounting groove; the stabilizing wheel assembly and the cutting block can move to the outside of the mounting groove in the radial direction of the main body pipe and be positioned, or can move to the inside of the mounting groove in the radial direction of the main body pipe and be positioned. Meanwhile, the functions of stabilizing a drilling tool and trimming the well wall are achieved, long-distance contact between the stabilizer and the well wall can be reduced through abutting of the stabilizing wheel assembly and the well wall, and therefore the use condition of the stabilizer can
