Festool Granat grit chart.

Expensive, P-graded, and worth knowing which machine it goes on.

Granat is Festool’s general-purpose disc for wood and paint. Festool describes the grain as self-sharpening ceramic with stable aluminum oxide, under a non-stick coating that keeps dust from packing in. It is graded in FEPA P-grades, and the hole pattern is built for Festool’s dust extraction, which is half of why it lasts.

It is not cheap. What you buy is a disc that keeps cutting at the same rate for longer, which on a full day of cabinet faces means fewer disc changes and a scratch that doesn’t drift halfway through a panel.

Rotex vs ETS: which one the disc goes on

An ETS is a random orbital sander, nothing else: the pad spins freely while it orbits, so the scratch never repeats and the finish stays clean. The number after the slash in the model name is the orbit in millimetres, so an ETS EC 125/3 runs a 3 mm stroke, which suits finishing grits.

A Rotex is dual-mode. Flip a switch and the pad is gear-driven in a rotary-plus-orbit motion that removes material like a much more aggressive tool and can even polish; flip it back and it’s a random orbital. Coarse Granat (40 to 80) and a Rotex strip and flatten fast. Fine Granat (180 and up) and an ETS finish without fuss. One person, one sander, one budget: the ETS for furniture, the Rotex if stripping and refinishing is half the work. The full breakdown is in ETS EC 125 vs Rotex 150.

Questions people ask

Is Festool Granat P-graded?

Yes. Granat grades are FEPA P-grades, so above P220 they run coarser than CAMI-marked US paper with the same number.

What is Festool Granat made of?

Festool describes it as self-sharpening ceramic and stable aluminum oxide, with a non-stick coating that resists clogging.

Festool Rotex or ETS?

An ETS is random orbital only and is the finishing sander. A Rotex adds a gear-driven rotary mode for fast stock removal and polishing. Mostly finishing work: ETS. Lots of stripping and refinishing: Rotex.
