The RTS 400 REQ-Plus delivers 250 watts of power in a 2.4-pound package, making it ideal for finish carpenters tackling vertical surfaces and overhead work on Montana’s custom homes. This rectangular orbital sander replaces the older RTS 400 EQ with a 25% power increase, addressing the precision demands of window trim, door frames, and detail work that define high-end residential finishing.
Power and Performance for Detail Work
The 250-watt MMC motor runs at 6,000 to 12,000 RPM with stepless variable speed control. That power bump matters when stripping old finishes from log home window frames or prepping timber frame beams for staining. The 1/16-inch (2mm) fine sanding stroke keeps the finish smooth — critical for the clear-coated natural wood that dominates Montana’s luxury home market.
| Specification | Value |
|---|---|
| Power | 250W MMC Electronics |
| Speed Range | 6,000-12,000 RPM (variable) |
| Sanding Stroke | 1/16” (2mm) |
| Pad Size | 80 x 133mm (3-5/32” x 5-1/4”) |
| Weight | 2.4 lbs (1.1 kg) |
| Dust Port | 27mm diameter |
| Power Cord | 13.1 ft Plug-it cord |
The rectangular 80 x 133mm pad excels at edge work — getting into the corners of raised panel doors, following the profiles of window casings, and working the tight spaces where round sanders can’t reach. The included Protector edge guard prevents damage to adjacent surfaces when working up against finished millwork.
Dust Control That Actually Works
The turbo dust extraction system features a 27mm locking port that’s compatible with Festool CT dust extractors. The locking mechanism prevents the hose from pulling loose during overhead work — a real problem with friction-fit connections when you’re stretched out on a ladder sanding soffit boards.
The included reusable Longlife dust bag handles situations where dragging an extractor isn’t practical. Unlike disposable bags that clog and lose suction, this washable bag maintains airflow through multiple empties. The sander allows “virtually dust-free” work even without a connected extractor.
Built for Professional Use
MMC Electronics provides soft-start, constant speed under load, and thermal overload protection. The constant speed feature maintains consistent finish quality whether you’re barely kissing the surface or bearing down to remove stubborn mill glaze. Thermal protection prevents burnout during extended use — common when prepping an entire house worth of trim.
The Vibration-Stop balanced design reduces hand fatigue during prolonged use. Combined with rubberized grip surfaces, operators can work full days without the numbness that cheaper sanders cause. At only 2.6 lbs shipping weight, it’s light enough for extended overhead sessions.
The 3-year limited warranty includes wear-and-tear coverage — not just manufacturing defects. Festool stands behind professional use, which matters when the nearest service center might be hours away from rural jobsites.
What’s in the Systainer
The kit includes the RTS 400 REQ sander, StickFix sanding pad, Protector edge guard, Longlife dust bag, 13-foot Plug-it power cord, and a Systainer³ M 187 case. A Clean-Tec bayonet-style adapter retrofits older CT hoses to the new locking port.
The Systainer integration matters for contractors managing multiple Festool tools. Stack them in the truck, grab the ones needed for today’s task, and know everything’s protected and organized.
Bottom Line
The RTS 400 REQ-Plus earns its keep on finish work where precision matters more than raw material removal. The 25% power increase over the previous model speeds up stripping operations without sacrificing the fine control needed for final sanding. The rectangular pad design makes it particularly effective for overhead work and vertical surfaces in tight corners.
For Montana contractors working high-end residential, the combination of power, dust control, and edge-work capability justifies the Festool premium. Users rate it 5.0/5.0 stars, emphasizing low vibration and excellent dust collection. The lightweight design and overhead comfort make it the right tool for the detail work that separates custom finishing from production work.
Frequently Asked Questions
What makes the RTS 400 different from round orbital sanders?
The rectangular 80 x 133mm pad gets into corners and along edges where round pads can’t reach. The narrow profile allows sanding on edges and frame members — critical for window and door trim work.
Does the dust collection really work without an extractor?
Yes — Festool claims “virtually dust-free” operation with just the included reusable bag. The turbo dust extraction design maintains suction, though connecting a CT extractor provides superior collection for all-day use.
How does the 250W motor compare to other finish sanders?
It’s 25% more powerful than the previous RTS 400 model. The MMC electronics maintain constant speed under load, preventing the bogging that happens with lesser sanders when removing tough coatings.
What abrasives work with the StickFix system?
The sander accepts Festool Granat, Rubin, and other 80x133mm StickFix abrasives. The hook-and-loop design allows quick changes between grits and lets you reuse partially worn sheets.
