Comparison with BLACK & DECKER BDCS80I

However, in spite of the similar costs, you are not necessarily getting more, and I am not talking about the accompanying accessories. The BDCS80I only has a maximum torque of 125 in. lbs. It has a variable speed trigger, but its RPM only has a maximum of 2,200. It is lighter at only 2 lbs. but packs less power compared to the BDI20B.

Torque equals power and speed complements that. If you are looking for a powerful tool for those large home projects, the BDI20B is the obvious choice. It may be pricier and you may need to shell out some more for the battery and charger, however, its heavy-duty capacity makes it sell itself.
