Festool FAQ: Granat Abrasives, Anchor Center Kit, Finger Ratchets, and Adjustable Wrench Tips

What this FAQ is really about

I'm a lead carpenter in a custom millwork shop, and I've been using Festool tools professionally since 2018. I've also made nine genuinely stupid setup mistakes that totaled roughly $4,200 in wasted material and labor. That's why our crew now has a checklist, and why people ask me which Festool stuff is actually worth the money.

These are the questions that come up most on the job site. No marketing language — just what I've learned after paying for it.

• Is Festool worth the price?
• What's the deal with Festool Granat abrasives in 6" P40 and P50?
• What is the Anchor Center anchor kit?
• Is a finger ratchet worth carrying?
• How does an adjustable wrench work without chewing up fasteners?
• Is the Festool dust extractor worth it?
• Which Festool tool should you buy first?

Is Festool actually worth it?

Depends. If you compare list price only, Festool tools look expensive. But I stop comparing list price the moment a project has a deadline. What Festool sells isn't just power — it's certainty. Knowing the rail is straight, the dust is contained, and the sandpaper actually connects to the sander saves time you can't get back.

I think of tool buying the same way I think of online printing. Standard business cards with no deadline? Buy the low-cost option. Event materials with a date printed on the order? Use a rush service like 48 Hour Print, because guaranteed turnaround is what you're paying for. Festool plays that role in my shop: less mystery, more certainty.

In my opinion, the lower-priced option can still produce good work — it's just less predictable. And for a professional, unpredictability is the real cost.

What about Festool Granat abrasives in 6" P40 and P50?

Granat is my go-to for sanding paint and coated surfaces. The 6" P40 is coarse; that's for stripping old finish down to bare wood. P50 is also coarse but leaves a finer scratch, so it's what I use after P40 before moving to P80 or P120. If you're sanding bare timber, you probably don't need these. For paint removal, Granat outlasts cheaper abrasives by roughly double in my experience.

Here's the mistake that still makes me wince. In September 2022, I ordered 6" Granat P40 / P50 for a six-door refinishing job, but I grabbed P12 off the shelf (that's a heavy stock-removal grit, not a finish grit). Nobody checked before the crew started. Three veneer doors were sanded through before we caught it. That was about $1,100 in material and a three-day delay — all because we trusted the label on the box.

Since then, the rule is: check the grit stamp on every sleeve when it comes out of the Systainer. Sounds obvious, but it took losing money for me to actually do it.

On price: I paid roughly $0.85 to $1.15 per sheet for 6" Granat in mixed packs from a regional dealer in January 2025. Verify current quotes before you order.

What is the Anchor Center anchor kit?

The Anchor Center anchor kit is a centering guide that fits into the Centrotec chuck and keeps a masonry anchor, tapcon, or drill bit aligned with the hole axis. Sounds like a minor piece of plastic, right? Until a hole drifts and the anchor jams sideways into a finished slab.

That happened to me in May 2023 on a railing post retrofit. I 'eyeballed' the drill bit, the hole walked about 3/16", and the anchor couldn't pull the post tight. Replacing the misaligned anchor cost us $380 in materials and a full day of rework. With the centering guide, the hole goes where you aimed, and the anchor has a clean straight-sided bore to bite into.

If you're not setting anchors in concrete or masonry regularly, it's not a first purchase. But when you need it, it changes the job from 'hope it lands close enough' to measured and predictable.

Is a finger ratchet worth carrying?

Yes, but not for the reasons the product listing wants you to believe. I carry a finger ratchet because it reaches fasteners that a full-size ratchet can't. Two places it has saved me on Festool work: the nut on the bottom of the MFT hinge plate and the connector bolts on guide rails when the rail is already set against a wall. A finger ratchet adds maybe 170 grams to my pouch and prevents a lot of cursing.

That said, I wasted $14 on a cheap one in October 2021 and the thumb wheel stripped within a month. The better unit costs triple, but it still works four years later. On that one, buying once truly cost less than buying twice.

How does an adjustable wrench work without chewing up fasteners?

Most adjustable wrench failures come down to orientation, not sharpness. The wrench has a fixed jaw and a movable jaw driven by a worm gear. The worm gear has a small amount of play, so if the movable jaw takes the load, the wrench loses grip, and the nut gets rounded.

The rule I teach new guys: pull on the wrench so the fixed jaw carries the force. Set the wrench so the movable jaw is on the trailing side, not the leading side, and pull toward the fixed jaw. If you can't pull that way, flip the wrench over instead of pushing.

Also check the jaw opening before every pull. An adjustable wrench always has a little slack — half a millimeter on most models. Closing the jaw tight against the nut before applying force prevents most slips. The 'wobble' people complain about isn't always the tool's fault; it's usually the jaw orientation.

Is the Festool dust extractor worth it?

I'm not going to promise 100% dust-free because that's marketing nonsense. There will be dust when you empty the bag. But the CT extractor makes a serious difference. After using it with the 6" sander and the track saw, I don't spend the day breathing fine dust, and sandpaper seems to last longer because the paper isn't loading up with the dust you'd normally be dragging across the work.

For a pro, dust extraction is a tool-life and health issue, not a luxury. The Systainer design also means the whole sander-and-vac stack rolls together into one package. That compact setup saves me maybe 20 minutes per job site. After a few jobs, that time pays for the price difference.

Which Festool tool should you buy first?

If I had a budget of around $1,200 and worked with sheet goods every week, I'd buy the CT MIDI dust extractor first and then a track saw — not a router, not a domino joiner. The track saw with a rail gives you straight cuts in under a minute, and the extractor keeps the dust problem manageable. That combination is the fastest route to everyday certainty.

If your work is mostly sanding and finishing, start with the sander and extraction instead. A 6" sander plus a box of Granat paper will change your results more than whatever shiny new thing comes out next spring.

Either way, plan the whole system before you buy the first tool. That's the mistake that costs our team the most: single-tool purchases that don't connect to a system, followed by hours of improvised clamps, hoses, rails, chips, and trips to the hardware store.
