Key Features

Faster Stock Removal

The updated 250W motor helps the sander remove material up to 25% faster than the previous version, which means less time leaning on the tool and more time moving to finish sanding.

One-Hand Control

At just 2.6 lbs, this orbital sander is easy to run on flat panels, vertical work, and overhead surfaces without beating up your wrist or shoulder.

Cleaner Sanding Setup

The locking dust port, reusable dust bag, and Festool extractor compatibility give you flexible dust control whether you are in the shop or working where a vac hookup is not practical.

Overview

The Festool RTS 400 REQ Orbital Sander Set w/ Granat Abrasive Value Set Systainer is a compact finish sander built for detail sanding, edge work, and flat surface prep where control matters more than brute size. This is a finish orbital sander designed for one-handed sanding on flat, vertical, and overhead surfaces. If you are a cabinet installer, trim carpenter, painter, remodeler, or serious DIY user who needs clean finish work without dragging around a bulky machine, this setup makes a lot of sense. Model Number: 576054-578194.

What separates this sander from basic sheet sanders is how it balances speed, control, and dust collection. Festool updated the RTS 400 REQ with a more powerful 250W motor, and that translates into quicker material removal without giving up the finish quality this style of sander is bought for in the first place. Festool states it can work up to 25% faster when removing material, which matters when you are cleaning up milled edges, breaking sharp corners, or getting panels ready for paint or finish.

The small rectangular sanding format is a big part of the appeal. It gives you better access along edges, narrow parts, and face frames than a larger random orbit sander, and the 80 x 133 mm abrasive format is well suited to trim, cabinet parts, doors, shelving, and touch-up sanding between coats. The low tool weight of only 2.6 lbs helps keep the pad planted without feeling top-heavy, especially when you are sanding vertically or reaching overhead.

Festool also built this RTS 400 REQ around jobsite comfort. The improved soft-grip coating gives you a more secure hold during longer sanding sessions, while vibration-stop balancing helps reduce fatigue. That is not just a comfort feature. Less hand fatigue usually means steadier control, more even pressure, and a more consistent finish across the workpiece.

Dust control is another strong point here. The sander uses a locking dust port and includes a reusable dust bag, so you can keep working cleaner even when you are away from a dedicated extractor. When you are in the shop, it is designed to pair with Festool CT Dust Extractors for a more complete low-dust sanding setup. Festool also includes a Clean-Tec bayonet-style dust port to retrofit older hoses, which is the kind of practical detail that saves frustration if your hose setup is not the newest generation.

This set is more than just the sander itself. You get the Plug-it power cord, a soft StickFix sanding pad, the reusable dust bag, the bayonet-style dust port adapter, and a Systainer3 M 187 for organized storage and transport. The product name also calls out the Granat abrasive value set, so this package is aimed at users who want a ready-to-work finishing setup instead of piecing everything together one item at a time.

If your work centers on finish carpentry, cabinetry, built-ins, furniture touch-up, or paint prep, this Festool orbital sander fits right in. It is not the tool you buy for heavy leveling on big slab tops. It is the one you reach for when you need control, a light hand, and a cleaner result on detailed work where a larger sander feels clumsy.

Stay in Control on Detail Work

This is the kind of finish sander you use when a bigger tool starts feeling like too much machine for the job. The compact body and rectangular pad make it easier to stay flat on edges and smaller parts.

• Compact one-handed design for flat, vertical, and overhead sanding
• Soft StickFix sanding pad helps the tool stay controlled on finish surfaces

Cleaner Sanding Without Slowing Down

Dust is more than a cleanup problem. It affects visibility, finish quality, and how long you can comfortably work indoors. This setup gives you options whether you are tied into extraction or working more mobile.

• Locking dust port helps keep the hose connection secure during use
• Reusable dust bag allows near dust-free sanding when an extractor is not connected

Ready to Store and Ready to Travel

A good finish tool gets used more when it is packed right and easy to grab. The included Systainer keeps the sander, accessories, and abrasive setup together so the tool shows up ready for the next job.

• Includes Systainer3 M 187 for organized transport and storage
• Plug-it power cord and dust accessories stay with the tool instead of getting lost in a gang box
