Is the Flex FX4111 worth it over a cheaper 12V multi-tool?

If you already own Flex 24V batteries, yes: it has more power, lower vibration and Starlock Max blade changes. A 12V tool is lighter and cheaper for occasional light trimming.

Does it use standard OIS blades?

No. It uses the Starlock Max accessory system, so you need Starlock or Starlock Max blades. Adapters exist but add bulk.

How long does the 2.5Ah battery last?

Runtime depends on the task. Short plunge cuts and trim work last well; continuous sanding drains the pack quickly, so a second battery helps.

What comes in the kit?

The multi-tool, a 2.5Ah battery, a 160W fast charger, a depth guide, a 1-1/4-inch bi-metal plunge blade, a 1-1/4-inch high-carbon steel plunge blade and a bag.

Can it cut drywall and nails?

Yes. With a bi-metal blade it handles drywall, plastic and embedded nails; use the high-carbon blade for clean wood cuts.

What is the warranty?

Flex covers the tool with a 5-year end-to-end warranty.

About the FLEX FX4111-1A 24V Oscillating Multi-Tool Kit

The FLEX FX4111-1A is a 24V cordless oscillating multi-tool with a brushless motor. It runs at up to 20,000 OPM and is used to cut, trim, plunge, sand, grind, and scrape. The kit includes a 2.5Ah battery and a 160W fast charger.

The motor is a Sensor-Free brushless design, with the sensors moved away from the motor. The 3D Starlock connection transfers power from the motor to the blade. A keyless blade eject lets you change blades without touching hot ones. Vibration suppression isolates the tool and the user from vibration.

A built-in LED light illuminates dark work areas. The tool works with all FLEX 24V batteries, chargers, and tools. It is covered by a 5-year, end-to-end warranty.
