The biggest issue with the smaller M12 Ratchets is that they don't have the greatest amount of torque. That's where the  Right Angle Impact Wrench comes in. It produces up to 220ft-lbs of nut-busting torque and fits in places a normal impact won't. It has 4 modes which allow you to set your RPM and IPM with the 4th mode having auto-shutoff in forward and bolt removal mode in reverse. You'll definitely want one of these in your cabinet.
