Flex announced and demonstrated its FX3361 24V cordless 3-in-1 Mini Polisher at SEMA 2026. It uses interchangeable adapters for rotary, dual-action and gear-driven polishing, and its planned kit price is $599.99; retail availability and hands-on performance have not yet been confirmed.
Flex announced and showcased its FX3361 24V cordless 3-in-1 Mini Polisher at SEMA 2026, introducing a compact tool designed to handle rotary, dual-action and gear-driven polishing by swapping adapters. The planned kit price is $599.99, and the product has not yet reached retailers, according to Pro Tool Reviews.
The polisher changes its action through tool-free interchangeable adapters, rather than a selector on the tool. The kit is slated to include a rotary adapter, dual-action adapters with 3mm, 6mm and 12mm orbits, and a gear-driven adapter with a 6mm orbit. The tool accommodates backing plates and pads of 1, 2 and 3 inches, aimed at work on smaller areas where a full-size polisher may be cumbersome.
Flex lists adjustable rotation from 1,000 to 4,000 RPM, with a 6,000 RPM Turbo mode. Its stated orbit rate is 2,000 to 8,000 OPM, rising to 12,000 OPM in Turbo mode. The tool uses a brushless motor with a belt drive. The report says the belt drive is intended to reduce vibration and noise and improve smoothness and control; those are design aims, not independently established results from extended use.
The planned $599.99 kit includes two 2.5Ah batteries, a 160W fast charger, adapters, pads and a soft bag. Flex is offering a five-year limited warranty on the tool, batteries and charger. Listed features also include touch-sensitive speed controls intended to work with nitrile gloves, a speed-lock button, an LED RPM display and a work light with three color-temperature settings.
Three Polishing Actions in One Kit
For detailers, the central potential benefit is less time changing tools when moving between different polishing tasks. A rotary action, dual-action options and a gear-driven mode offer different approaches to paint correction and finishing in one cordless package. The gear-driven adapter may be useful when maintaining pad movement is a concern, though the source does not provide comparative test results showing how often it prevents stalls.
The cordless 24V platform may appeal to mobile detailers or shops that want to work without managing a power cord around a vehicle. However, a $599.99 kit is a substantial purchase. Whether it replaces multiple existing tools, or proves worthwhile for a particular shop, will depend on real-world performance, battery runtime and the work being done—details not established in the announcement report.

How the Adapter System Works
Flex has a long-standing presence in the polisher category, according to Pro Tool Reviews. The newly announced model builds on that product area with a mini format and interchangeable drive adapters. Instead of selecting a mode electronically, users change the mechanism fitted to the tool. The adapters provide the different actions and orbit sizes.
The model is listed at 2.0 pounds bare, runs on Flex 24V batteries and has a maximum pad size of 3 inches. Those specifications frame it as a tool for smaller-scale detailing work, rather than a direct substitute for every larger polisher. The report describes the product as an industry first, but that characterization is the publication’s account of Flex’s announcement, not an independently verified market survey.
“For detailers, efficiency is just as important as precision. By combining three polishing modes in one compact tool, we’re helping detailers streamline their workflow, spend less time switching between tools and more time getting the job done.”
— Kevin Gee, Flex vice president of Pro Product Development
Retail Date and Field Results
Flex has not provided a specific retail release date in the source report, which says only that the tool is expected in stores soon. The listed price and kit contents are presented as planned specifications, and buyers should confirm availability and package details with retailers when the product launches.
The report does not provide extended hands-on testing, measured battery runtime, polishing results across paint types, or comparisons with separate tools. It is also not clear whether Flex will adapt the three-action concept to larger polishers. The product’s stated design goals should not be treated as proven performance outcomes before broader testing.
Retail Launch and Independent Testing
The next near-term milestone is the polisher’s arrival at retailers. Flex has not stated an exact date in the material available. Once the kit is on sale, detailers and reviewers can assess its battery life, control, vibration, adapter changes and finish quality under working conditions, and compare its value with buying separate tools.
For now, potential buyers can compare the announced kit contents and specifications with their own polishing needs, while checking with Flex or retailers for current stock and final purchase terms. Any plans to extend the system to larger polishers remain unconfirmed.
