The STIHL 4314 682 3101 is a genuine OEM 3-inch auger blade designed for the STIHL BT 45 earth auger. This replaceable cutting blade mounts to the 4-inch planting auger head and provides efficient penetration into soil when drilling holes for seedlings, shrubs, fence posts and landscaping applications. Manufactured from hardened steel, it delivers excellent wear resistance and can be replaced independently of the auger head, reducing maintenance costs.
