Part Number: 5T30-CThe 5T30c is a carbide tipped version of the 5T30 Super Tooth. Carbide is used for greater abrasion resistance and longer life. It fits on Combo and Pengo Style augers 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 inside pocket closest to the center pilot and used in conjunction with a 35, 35HF or 1336 blade in the outside pocket. Includes rubber lock.
