Our take on the Ryobi USB Lithium Cordless 4V Rotary Tool Kit

The Ryobi USB Lithium Rotary Tool is a compact 4V cordless rotary tool with five speed settings and a top speed of 25,000 RPM. Its quick-change collet swaps 1/8-inch accessories about four times faster than a standard collet, and the kit includes 15 accessories, a wrench and a storage case. It weighs just over half a pound with the battery, and the 2.0Ah USB Lithium battery has a USB-C port that can also charge a phone. At $47.97 at Walmart as of November 5, 2026, it sits at the low end of its recent price range.

What reviewers say

Owners treat it as a handy light-duty rotary tool for crafts and quick fixes, and like the fast accessory changes and low weight. The main complaint is that the 4V motor bogs down on tougher materials and the battery runs out on longer sessions.

What people mention
  • PowerCriticisedOwners say the 4V motor stalls or slows on harder materials and heavier cuts.
  • Accessory changesPraisedThe quick-change collet is called out as much faster than a standard wrench-and-collet setup.
  • Battery lifeMixedThe 2.0Ah battery is fine for short jobs but drains quickly during longer sanding or carving sessions.
  • Weight and sizePraisedAt just over half a pound it is easy to hold and control for detail work.
  • BuildMixedOwners find it solid for light use but not as durable as full-size rotary tools.

Questions and answers

Is the Ryobi 4V rotary tool strong enough for cutting metal?
Only for light work. The 4V brushed motor is meant for sanding, carving, polishing and small cuts; it will bog down on thick metal or hard wood.
What accessories fit this tool?
It uses standard 1/8-inch shank accessories, and the kit includes 15 bits plus a wrench and storage case.
How long does the 2.0Ah battery last?
Expect short runs of light work rather than long sessions. The LED indicator turns red when the charge is low, and the battery recharges over USB-C.
Can the battery charge my phone?
Yes. The included USB Lithium 2Ah battery has a USB-C port that works as a power bank for mobile devices.
How does it compare to a Dremel?
It is lighter and cheaper but less powerful. A corded Dremel has more torque and runs indefinitely; this tool suits light craft and touch-up jobs.
