All specs

Max torque (manufacturer rating)
What this means

Torque is the twisting force the tool can apply, usually listed in in-lbs or ft-lbs. Higher figures help with large fasteners, augers and hole saws. Ratings from different makers are not always measured the same way, so treat this as a rough guide rather than a direct comparison.

1,590 in-lbs [1]
Max speed
What this means

Max speed is the top no-load speed, in RPM for rotating tools. No-load means the tool is running free, so speed drops once it is working. On drills, many makers list a figure per gear: high for small bits, low for control with large bits or long screws.

0 - 650 / 0 - 1,800 / 0 - 2,400 RPM [1]
Tool length
What this means

Tool length is the front-to-back measurement published by the maker. A shorter tool fits between studs, joists and inside cabinets more easily; standard US framing is 16 inches on center, leaving about 14-1/2 inches between studs. Check whether the figure includes the chuck or bit holder.

7-3/4 in [2]
Batteries in box
What this means

This lists how many batteries come in the box, if any. Tool-only (bare) listings include no battery or charger, which suits buyers already on that battery platform. Two batteries let you charge one while working with the other.

1from the box list [1]
Battery capacity (each)
What this means

Amp-hours (Ah) is the battery's charge capacity. At the same voltage, a higher Ah pack runs longer between charges but is usually larger and heavier. Smaller packs keep the tool lighter for overhead and light work; larger packs suit saws, grinders and other high-draw tools.

4.0 Ahfrom the box list [1]
Chuck size1/2 in [1]
Weight with battery6.2 lbs [2]
UPC barcode197050014733 [1]
