STIHL auger bits are built from a single-piece alloy and feature an integrated pilot tip to start holes quickly, reduce wandering, and improve efficiency in mixed soils. Designed for the BT 131 auger, the lineup covers common hole sizes from 2" to 8".

  • Accurate starts thanks to the pilot tip
  • Durability: robust one-piece alloy construction
  • Versatility: broad diameter range, quick bit changes

Good to know: choose the diameter to match your post/plant and soil type. Wear proper PPE (gloves, eye & hearing protection).
