Mechanic ES240 SE Electric 24-in-1 Screwdriver Set – Precision Repair Kit

Every mobile repair shop bench has the same problem: screws of different sizes, different depths, and different torque needs, and one slow manual screwdriver trying to handle all of them. The Mechanic ES240 SE solves this with a hybrid electric and manual system in a single pen-sized body, so you don't lose time digging through a drawer of mismatched tools mid-repair.

At the core is a motor running at three adjustable speed gears, with reported speeds in the 145–210 RPM range depending on the gear selected. That range matters in practice. Low gear gives you the control you need on fine-pitch screws around the motherboard or camera module, where one slip can strip the thread or scratch a nearby component. Higher gear speeds up repetitive work like back cover screws or battery bracket screws, where you're removing the same screw type ten times a day.

The dual-mode design is what separates this from a basic electric screwdriver. When the tool is powered off or the battery drains, the shaft locks automatically and the body works as a manual screwdriver, delivering up to 3N.m of torque. This matters for any technician who's dealt with factory-tightened screws that won't budge under light electric torque. You start manual to break the initial resistance, then switch to electric mode to extract the screw fully, a workflow that protects the internal gearing and avoids forcing the motor against a stuck screw. The same logic applies in reverse during reassembly: tighten with the motor for speed, then finish the last turn manually on fragile plastic clips so you don't strip the mount.

The 24-piece bit set is built from S2 steel with anti-rust treatment, covering the Phillips, Torx, Pentalobe, and flathead sizes used across phones, tablets, laptops, and small electronics. Bits use a universal 4mm shank, so they seat into the magnetic chuck without play, and the magnetism also makes it easier to lift a dropped screw off the board instead of fishing for it with tweezers. For technicians who work across mixed brands, this single kit replaces a stack of separate precision screwdrivers.

Visibility is the part that's easy to overlook until you're working on a multi-layer PCB under a microscope. The ES240 SE has built-in ring LEDs positioned around the bit tip, lighting the screw head directly instead of casting a shadow from the tool body, which is what happens with a normal desk lamp or microscope ring light when the tool itself blocks the angle. On a dense board where you're hunting for a tiny screw near an IC or connector, that direct lighting reduces the chance of misaligning the bit and slipping onto a component pad.

Battery life is built around a 500mAh lithium cell with reported continuous run time around 120 minutes on a charge, and a battery level indicator on the body so you're not caught mid-repair with a dead tool. Charging is via a standard port, which keeps it consistent with the rest of your bench equipment.

In day-to-day workshop use, this tool fits into almost every repair job before the real diagnostic work starts. You can't get to a dead phone after flash, a charging issue, or a display problem until the back cover and internal screws are out, and a slow or mismatched screwdriver set adds unnecessary time to every single job. For shops running high ticket volume, shaving even thirty seconds off disassembly and reassembly on each unit adds up fast across a full day's bench work.

It also pairs naturally with the rest of a disassembly station. Once the case is open, the next tools on the bench are usually a microscope for board inspection, an ISP pinout tool or test box for diagnosing a hang on logo or boot loop issue, and a soldering or hot air station if a jumper needs to go in or an IC needs to come off. The ES240 SE doesn't replace those tools, it gets you into the device fast and without stripped screws, which protects the board you're about to work on with everything else on your bench.

For a repair shop or service center stocking a single all-purpose screwdriver, the combination of adjustable speed, manual override torque, direct LED lighting, and a complete 24-bit set makes the ES240 SE a practical choice that holds up across phone repair, tablet repair, and general electronics disassembly work.
