Two new Snap-on 7.2-volt Lithium Series power tools are the 1/4-in. Quick Change screwdriver (CTS661) and the 3/8-in. impact wrench (CT661). 

Both tools feature a removable 7.2-volt lithium battery for longer work periods, and both have a variable-speed toggle switch allowing the user to go quickly from forward to reverse. There’s a brake for quick motor shutdown. They both have an over-current mechanism that protects the electronics and prevents overheating, and under-voltage protection that prevents the battery from being drawn down too low. 

The CTS661 screwdriver offers 100 lb in. of torque, a faster free speed (400 rpm) than the CTS561CL, and a nine-position clutch.

With 70 lb ft of torque, an anvil stop, and a screened motor to keep debris out, the CT661 impact tool’s small size allows it to get into tight spaces like under the dash or the firewall.
