ETS EC 125/3 & 150/3 Sanders – Precision for Fine Finishing
- Pad Size: 5" (ETS EC 125/3) or 6" (ETS EC 150/3)
- Weight: Approx. 2.6 – 3.9 lbs
- Stroke: 3 mm
- Accessories: Use with edge guides like the AH-ES-ETS/ETSC sanding guide for edge consistency.
- Best For: Finish carpenters, furniture builders, and woodworkers who require ultra-smooth surfaces before final finishing.
- Industry Use: Woodworking, cabinetry, fine finish work
These compact electric sanders offer a short 3mm sanding stroke, ideal for high-precision surface prep, sealer sanding, and between-coat abrasion. The brushless EC-TEC motor ensures long life and quiet operation, while integrated vibration control makes it comfortable for all-day use. Pair with Granat abrasives for top-tier results.
Use Case: Custom Cabinet Shop
Imagine a high-end cabinet shop where precision and consistency are everything. After milling and assembling hardwood frames for built-in cabinetry, the ETS EC 150/3 is used to prep surfaces for stain.
The 3mm stroke gives just enough abrasion to smooth joints and remove mill marks without burning through edge banding or veneer.
A tech might switch between P120 to P220 Granat discs as they work across drawer faces, stile-and-rail doors, and end panels, knowing the low vibration design allows for fatigue-free sanding over long shifts.
In this environment, a clean surface before applying toner or clear coat is crucial, especially for darker stains that show swirl marks. The ETS EC's brushless motor ensures consistent pad speed under pressure, and when connected to a CT 26 E dust extractor, the jobsite stays dust-free, allowing painters to begin finishing without waiting.
ETSC 125 Cordless Sander – Go Anywhere, Sand Everywhere
- Pad Size: 5"
- Weight: 2.6 lbs (without battery)
- Accessories: Use with AC Power Adapter ACA 110-120/18V Ergo for continuous electrical operation. Includes 4-meter Plug-it power cable.
- Best For: On-site touchups, mobile work, and remote locations where cords aren't practical
- Industry Use: Trim installation, remodeling, mobile service jobs
The ETSC 125 Cordless Sander combines Festool's ergonomic design with the freedom of cordless mobility. It uses the same 5" backing pad as the ETS EC 125 and features a 3mm stroke for finish sanding. Powered by an 18V battery, it's perfect for tight installs, in-place finishing, or pairing with a Festool Dust Extractor via Bluetooth remote.
Use Case: Jobsite Trim Install
A residential contractor finishing out a custom remodel brings the ETSC 125 Cordless Sander to a second-story bedroom where trim installation is underway. Crown molding has been caulked and primed, but filler spots and corner seams need smoothing before the final paint pass.
Plugging in isn't an option. The space is tight, and outlets are limited. The tech loads a P180 Granat disc, adjusts the speed dial, and effortlessly sands trim lines, casing edges, and touch-up putty without cords tangling, ladders, or stepping hazards.
The freedom to move room-to-room with just a Bluetooth-equipped dust extractor and battery bank makes cordless sanding more efficient than ever. In addition, painters benefit from the tool's dust collection capabilities, avoiding contamination that would otherwise ruin the finish coat.
ROTEX RO 90 DX – Multi-Mode Versatility in a Compact Body
- Pad Size: 3.5"
- Weight: 3.3 lbs
- Modes: Rotary, Random Orbital, Delta (triangular pad)
- Accessories: Add the Delta sanding head or polishing pads for corners and detailing.
- Best For: Edge work, tight corners, small surface sanding, and polish prep
- Industry Use: Furniture restoration, stairs, windows, custom millwork
The Festool RO 90 DX Multi-Mode Sander switches between aggressive rotary, fine random orbital, and delta detail sanding. Use the FastFix tool-free interface to switch to a triangular pad and tackle inside corners, trim profiles, or windows. A go-to tool for fine finish carpenters, especially when paired with Granat Net or Rubin 2 abrasives for targeted material removal or finishing.
Use Case: Staircase Renovation Project
A millworker renovating a historic staircase uses the RO 90 DX to restore each stair tread and baluster by hand. The treads have old varnish and embedded grime, while the risers are scuffed from years of wear.
In rotary mode, a Saphir 60-grit pad quickly removes the old finish and levels out imperfections. Then, switching to random orbital mode, the tech refines the surface using P100 and P150 Granat for a scratch-free prep before re-staining.
For the ornate railing and corners, they swap in the delta pad attachment. This allows precise sanding of the bullnose edge and tight newel post corners without over-sanding adjacent details. The ability to change modes and shapes mid-project cuts tool changeover time in half and minimizes the need for hand sanding.
ROTEX RO 125 & RO 150 – Aggressive Stock Removal to Mirror Finishes
- Pad Sizes: 5" (RO 125), 6" (RO 150)
- Weight: 4.4 – 5.7 lbs
- Modes: Rotary + Random Orbital
- Accessories: Pair with FastFix interface pads, polishing backing plates, and abrasive fleece pads for multi-surface performance.
- Best For: Removing paint, shaping, prepping surfaces, and final polishing
- Industry Use: Marine, metal fabrication, paint and body shops, general woodworking
The ROTEX line is known for high torque removal paired with the ability to finish sand and polish. Whether you're stripping paint from hulls or prepping metal panels for primer, these tools can handle heavy-duty work with finesse. Use Saphir abrasives for rough prep, and switch to Polishing Sponges or MPA 5010 polish for a clean shine.
Use Case: Boat Hull Restoration
In a marine repair shop, a technician uses the RO 150 to restore the fiberglass hull of a fishing boat. The job involves stripping flaking gel coat, smoothing patch repairs, and prepping the surface for re-coating.
With rotary mode and a Saphir 40-grit abrasive, material is aggressively removed across wide surfaces, quickly leveling high spots and feathering transitions between old and new layers.
After surface shaping, the tech flips to random orbital mode to remove scratches and swirl marks left from coarse sanding. With P180 Granat discs, the surface is ready for primer application.
Once paint and clear coat are applied, a polishing sponge and Festool polishing compound turn the sander into a finishing tool, restoring gloss and depth to the final coat, making this a true three-in-one solution for marine, auto, or industrial restoration work.
PLANEX Drywall Sanders – Power & Reach for Large Wall Surfaces
- Models: PLANEX LHS 2 225, PLANEX Easy
- Pad Size: 8.9" (225 mm)
- Weight: Approx. 8.8 – 10.6 lbs
- Best For: Drywall sanding, ceiling prep, large wall flattening
- Accessories: Compatible with Granat abrasive packs, extension tubes, and adjustable suction control hoses.
- Industry Use: Drywall installation, painting contractors, renovation specialists
The PLANEX line offers extendable handles, direct-drive motors, and integrated LED surface inspection on the LHS 2 225. Ideal for leveling compound and avoiding oversanding. Use with Granat 225 mm abrasives and a CT 36 E AC Dust Extractor for a nearly dust-free jobsite.
Use Case: Commercial Drywall Finish Out
During a commercial office buildout, a drywall crew relies on the PLANEX LHS 2 225 to sand full-height walls and ceilings in a 5,000 sq. ft. space. The drywall has already been taped and joint compound applied, but everything must be sanded flat to achieve a perfectly level finish for commercial-grade paint.
With its extendable handle and integrated LED ring light, the operator can spot uneven spots in real-time without additional inspection lights or ladders.
When working above drop ceilings or HVAC ducts, the variable-length body and overhead dust collection ensure the operator avoids fatigue, and cleanup is minimal.
Combined with a CT 36 E AC AutoClean Extractor, the PLANEX creates a near-zero dust environment, reducing respiratory risks and cleanup time. It is ideal for teams that finish and paint multiple units daily on commercial or multi-family builds.
