Max torque vs UWO

Most drill specs list 'max torque' in in-lb or Nm. This number is the peak, measured at stall — not what you get during normal use. A more honest metric is Unit Watts Out (UWO), which captures real-world power delivery.

A drill with 800 in-lb 'max torque' can easily lose to a 650 in-lb drill with higher UWO.

What to look for

For general-purpose drilling and fastening: aim for 500+ in-lb max torque and a brushless motor. For heavy applications (lag bolts, large hole saws): look for 700+ in-lb and a 1/2-inch chuck.

Clutch settings matter too

More clutch positions give you finer control. 21 positions is the standard for driver-drills. If you're driving cabinet screws or assembling furniture, more clutch positions means fewer stripped heads.
