Sander Types and Applications

Choosing the right Festool sander for your needs can seem complicated, but by understanding the key differences between the types of sanders, you can make an informed decision. Festool Australia's lineup of "Power Sanders" is designed to provide a solution for every application, from rapid material removal to fine finishing.

Understanding Sander Types

Orbital Sanders (Finishing Sanders)

Often referred to as finishing or sheet sanders, these tools are ideal for achieving a smooth, flawless surface. Their sanding pad moves in a tiny circular or orbital motion. Because of this, they are excellent for smoothing out large, flat areas and are particularly effective for sanding corners and edges due to their rectangular or triangular pad shape. They are less aggressive than other sander types, making them perfect for preparing surfaces for painting or staining and for intermediate sanding between coats.

Example: The DTS 400 REQ is a great example of a triangular-shaped orbital sander that excels at getting into tight corners.

Random Orbital Sanders

A versatile and popular choice, the random orbital sander combines two motions: the circular orbit of the pad and an independent rotation of the pad itself. This unique "random" action prevents the sandpaper from following the same path twice, which significantly reduces the risk of leaving circular scratch patterns or "swirl marks" on the surface. These sanders are fantastic for all-around use, as they can remove material quickly with a coarse grit and leave a high-quality finish with a finer grit.

Example: The ETSC 125 18V is a compact random orbital sander that is highly versatile.

Geared Random Orbital Sanders

Rotary sanders are designed for heavy-duty, high-performance tasks, with a pad that spins aggressively to remove large amounts of material quickly. This makes them suitable for stripping old paint or varnish, sanding down tough surfaces, and preparing surfaces for polishing. However, this aggressive action can leave a coarser finish, requiring a separate finishing step.

Festool’s ROTEX series offers a unique "geared random orbital" mode that combines the rapid material removal of a rotary sander with the fine finishing capabilities of a random orbital sander. With the flick of a switch, you can change the sanding mode. This dual-action functionality makes them incredibly versatile for both coarse sanding and fine finishing with a single tool.

Example: The RO 150 ROTEX 3 in 1 sander, for example, is a geared random orbital sander that can switch between aggressive rotary mode and a fine finishing random orbital mode, eliminating the need for a separate finishing sander.

The Right Sander for Your Needs

To choose the best Festool sander, consider the type of work you will be doing most often:

For Fine Finishing & Detail Work: If you are primarily working on delicate surfaces, preparing for a finish coat, or sanding in corners and edges, a standard orbital sander like the RTS 400 is your best bet.
For General-Purpose Sanding: A random orbital sander is the ideal all-rounder for most woodworking and home improvement projects. It offers a great balance of material removal and a fine, swirl-free finish. The ETS series from Festool is a perfect choice here.
For Heavy-Duty & Multi-Purpose Tasks: If you need a single tool to handle both aggressive material removal and high-quality finishing, a geared random orbital sander from the ROTEX series is the ultimate solution.
Ultimately, the best sander is the one that aligns with your most frequent applications. Festool's system-based approach ensures that no matter which sander you choose, it will integrate perfectly with their dust extraction systems and a wide range of abrasives for a healthier, more efficient workflow.
