The DCF845P1 is the benchmark: a brushless motor produces 1,825 in-lbs and 3,400 rpm, enough to bury 3 inch structural screws and drive lag bolts into framing. A three speed switch lets you drop to a low, controlled setting for small fasteners, which protects screw heads and soft materials. That range is what makes it work for both framing and finish carpentry.
Compared with the DCF787D1 it is more powerful but less compact, and against the Craftsman CMCF800C1's 1,460 in-lbs it has roughly 25 percent more torque. It is also louder than the DCF870B, because the conventional hammer and anvil is a noisy mechanism. For most buyers the extra torque is worth the cost, since stalled screws are the main cause of broken bits.
The kit includes a battery and charger, so it is ready on arrival. Replace worn bits regularly, because a rounded bit wastes the tool's torque, and keep the hex collet clean of dust.
