Purchase the threaded adapter with your heavy-duty variant of this auger to fit your Stihl BT45 Powerheads.

About Heavy-Duty Augers

Heavy Duty is the most rugged and versatile option for this auger. Use the dropdown menu above to choose the “Heavy Duty – Clay, Rocky, or Professional Use” option. The heavy-duty hex adaptor is a replaceable auger tip that will help you tackle the most challenging digging tasks without damaging the main auger and is included when you purchase the Heavy Duty option. The leading portion of the digging tip has replaceable auger blades. This allows for an easier and more cost-efficient way to keep your equipment performing in top condition.

In addition, the auger bit will fit any drill (i.e. Stihl BT45) with a threaded end when purchased with a threaded adapter (sold separately). Our adaptable heavy-duty augers feature 2 holes with pins for mounting and will fit auger powerheads with a 3/4-inch shaft. This is a smart option for professional landscaping businesses that need to switch between drills and powerheads throughout the day.
