Teeth for Lowe LP and other Drive on style auger teeth, comes with rubber lock.
Auger bits are normally set up with flat teeth in the outside positions and chisel teeth in the inner positions.  For example, a 24" bit that has eight total tooth positions would have two flat teeth and six chisel teeth.  Depending on you digging conditions you can put all flat teeth, all chisel teeth, or the flat/chisel combo on your auger bit.
