It's perfect for Skid Steers and Excavators up to 4.5 tons when drilling in earth. This flat - tooth auger bit has chisel ripping teeth on inner pockets, making it ideal for general earth and clay drilling. With multi - facet tungsten teeth, it can also handle granulated and soft fracturable rock.

Using the A4 Earth Auger Bit is quite straightforward. First, make sure your Skid Steer or Excavator is up to 4.5 tons as this bit is designed for such machines. Connect the bit properly to your equipment following the manufacturer's instructions. When drilling in earth, aim for a speed between 55 - 65. For clay, keep the speed at 45 - 55, and for shale or fracturable rock, 20 - 45 is the best range. Don't try to use it on heavy rock as it's not suitable. If you need to replace the teeth, thanks to Digga's knock - in, knock - out tooth locking system, you won't need any complicated tools. Just follow the simple process to remove and install new teeth. As for maintenance, after each use, clean the bit thoroughly to remove any dirt or debris. Check the teeth regularly for wear and tear, and replace them when they start to show significant damage. Also, inspect the body of the auger for any signs of cracks or dents. Keeping it in a dry place when not in use will also help prolong its lifespan.
