Compact 4V screwdriver set for tight spaces
The Craftsman CMHT66718B20 is a 12-piece cordless kit built around a 4V MAX lithium-ion cell. Its 40 mm body matches the length of a standard manual driver so it reaches deep cabinets, electrical boxes and appliance panels without forearm strain. Homeowners, maintenance techs and DIY assemblers get push-button operation and a quick-change hex collet that accepts 1-inch bits.
300 RPM no-load speed for rapid driving
The single figure that decides fit is the 300 RPM no-load rating. It delivers up to four times the turning speed of hand driving for wood screws, sheet-metal screws and light machine fasteners. Variable-speed trigger control lets you feather the start, while the integrated 0.472 kg motor keeps the tool light enough for overhead work. Buyers who need high-torque impact action or drilling capacity should look elsewhere.
Micro-USB charging and LED work light
A Micro-USB port recharges the internal battery from any USB power source; a wall adapter is not supplied. The 3-stage charge indicator shows remaining capacity at a glance to prevent mid-job stoppages. LEDs activate automatically when the trigger is pressed, illuminating the fastener head in shadowed corners. The 12-pack includes assorted hex and Phillips bits held in the compact case.

Questions about this item
How does the 300 RPM no-load speed translate when I am actually driving screws?
The motor spins at 300 RPM with no resistance; under load the speed drops, but the maker states it drives screws up to four times faster than manual turning.
What does the Micro-USB charging port limit in practice?
It charges the integrated 4 V lithium-ion battery from any standard USB power source; a wall adapter is not included.
Will the 40 mm body and 1-inch hex chuck fit in my tool bag and accept standard bits?
The driver is 40 mm long, weighs 0.472 kg, and uses a 1-inch hex quick-change collet that holds 1-inch hex and Phillips bits securely.
