The 5T30 Super Tooth is an optional tooth for Ground Hog Combo and Pengo Style augers. It fits in place of a 35 blade and has a more pointed tip for breaking up hard soil. On augers with 2 side blades this tooth is usually used in the pocket closest to the center pilot and used in conjunction with a 35, 35HF or 1336 blade in the outside pocket. Includes rubber lock.
