137990 P-21-RR Carbite Tooth (rock head)

Pengo’s Aggressor augers are all made in the USA. Pengo’s patented 40/50 dual angle bolt on cutting can be flipped from a 40 degree cut angle to a 50 degree cut angle for a more aggressive cut in clay and hard pack dirt. Aggressor augers also come standard with our Tri-Flow Pilot bit. The three cutting blades make it easier to start a hole and keep the bit straighter.
