Using The Mac Tools 4V Cordless Screwdriver

The controls are about as easy as they come. A simple thumb-activated forward and reverse button sits right on top of the tool, controlling its constant 300 RPM speed. One subtle touch you might miss is the forward arrow sticks up and the reverse is recessed. It’s a little thing that helps you focus on the fastener without having to look at the switch each time you press it.

The Mac Tools SBD4V has a low-torque motor that produces 8 inch-pounds of torque (0.9 Nm), so it doesn’t have the torque you might find in something like a drywall screwdriver. Once you reach the screwdriver’s torque limit, you can still operate it manually in forward or reverse.

Pro Tip: Stick with fasteners smaller than #8 diameter and less than 2 inches, or use a pre-drilled hole if you’re working with longer screws.

This one is perfect for working with delicate materials such as molded plastic. Around our shop, it’s incredibly useful for removing/installing vehicle panels, hose clamps, installing switch plates, and assembling tools with plastic parts.

Standout Features of the Mac Tools 4V Cordless Screwdriver

A couple of things stand out from most of the cordless screwdrivers we’ve used in the past.

First is the ergonomics of the design. To make room for a battery, many designs bulk up the handle and aren’t very comfortable for small and medium-size hands. Mac Tools’ design is much slimmer, though it is still a little thicker than a standard screwdriver.

There’s some give-and-take on the handle overmold. On one hand, its smooth design is very comfortable. On the other, it can get slick if your hands are sweaty or greasy.

The second thing is an IP54 rating. In addition to the water and dust resistance we normally think of with IP ratings, this screwdriver is also able to resist some of the common solvents you come across.

Additional Notes

An LED light is at the base of the handle shifts between green, yellow, red, and flashing red to indicate current battery life.
Five bright LEDs surround the collet and automatically turn on when the screwdriver is active and stay on for 10 seconds after the rotation has stopped.
The quick-change tool-free collet lets you swap out any 1/4-inch hex bits fast and holds bits more securely than a magnet alone.
The USB-C charging port is located at the rear of the tool and charges from 0% to 100% in 70 minutes.
