XXGO 4pc Diamond Multi Tool Blades for Grout Removal, Plaster & Mortar Cleanup (Compatible with Bosch / Dremel / Fein / Makita & more)
Product description
If your multitool work usually starts with stubborn grout or dried mortar, these XXGO diamond blades are built for the messy “clean it out properly” jobs. They’re aimed at detail work where you need control more than speed, and they come as a 4-pack so you’re not constantly hunting for the next replacement after small jobs.
What this is for (and where it fits)
These are oscillating multitool blades designed mainly for grout removal, plus follow-up cleanup on related build-up like plaster mortar, thinset, sanitary base, stucco, concrete block, brick joints and similar surfaces. The base description also flags that they’re not intended as a tile cutting blade and that they’re “mainly used for grout removal”.
On paper, that makes them a practical choice if you’re refreshing joints, cleaning out old grit, or shaping/abrading mortar lines rather than doing precision stone cutting. A good example use case: you line up the blade with a grout channel, run the tool gently along the joint and take out the top layer of grit so the grout can be re-applied cleanly (just be aware this kind of work rewards patience).
The main advantage: diamond for gritty joint work
The big selling point here is the diamond “multi tool blades” concept for dusty, abrasive material. Diamond abrasive faces tend to suit tasks like removing hardened residue from joints where standard edges can wear quickly. The listing also calls out compatibility with grout line widths, including working well with 1/8" grout lines.
There’s also a clear caution baked into the description: grout removal can easily lead to tile damage if you rush, so the blades are best used carefully.
Compatibility notes (important before you buy)
The product is marketed as compatible with a wide range of oscillating multitool platforms, including brands mentioned such as Bosch, Dremel, Fein, Makita, Milwaukee, Ridgid, Ryobi, Rockwell and more. However, the listing also states specific non-compatibilities.
Worth double-checking before purchase: - Not compatible with Bosch GOP40-30, Bosch Starlock 12V / 18V - Not compatible with Dremel Multimax MM30 / MM35 / MM40 / MM45 / MM50 - Not compatible with Fein FMM350QSL and Black and Decker
If you’ve got a less common mount type, it’s sensible to verify fit first rather than assume “compatible with” covers every variant.
Thickness, performance expectations, and the one limitation people notice
The description mentions a blade thickness of about 2mm, and it gives some guidance on grout width. It says they work fine with 1/8" grout lines, but are “not best” for 1/16” grout.
That matters because, for thinner joints, you may find the blade is simply less suited to the narrower channel. In other words, it’s not that it can’t work in every scenario—more that it may not give the cleanest, most controlled results on the smallest grout lines. If you mostly do fine 1/16” joints, you may want to look for blades specifically tuned for that width.
The other practical limitation is tied to user technique: grout is easy to damage, and the listing explicitly suggests taking your time removing grout carefully.
What stands out in everyday use
For the kinds of projects the listing calls out—grout removal, joints cleaning, and mortar/plaster cleanup—these blades are the sort of “get the job done” accessory you buy once and keep around for maintenance rounds.
They also seem more suited to shaping and grinding/dressing residue than heavy-duty cutting. The base description states they’re mainly used for grout removal and also mentions cutting/grinding/shaping tasks, but it separately notes they’re not intended for tile cutting granite hard wall.
Pros
- Focused on grout removal and related joint cleanup
- Diamond abrasive approach should suit hardened grit/grout residue
- 4-pack is convenient for multiple small jobs or phased renovation
- Explicit guidance on grout width (1/8" works well)
Cons
- Not best for 1/16” grout lines
- Requires careful handling, grout removal can damage tile if you rush
- Some popular multitool platforms are stated as not compatible, so mount type matters
Should you buy it?
Buy these XXGO diamond multitool blades if your main goal is clearing out grout and cleaning mortar/plaster residue from joints and you’re happy to work slowly for control. They make sense for typical DIY renovation tasks like refreshing sanitary base joints, tackling thinset/grit in wall joints, or preparing surfaces before re-grouting.
It’s probably not the best match if you mainly deal with very narrow 1/16” grout lines, or if your oscillating multitool falls into the explicitly listed “not compatible” categories. Also, if you’re expecting a tile cutting blade for hard surfaces, the description itself suggests these are not designed for that.
When you do buy, the most important thing to check is compatibility with your exact tool model/mount, and then plan to take your time along the grout line rather than forcing the blade.
Mini FAQ
Are these blades for cutting tiles?
No—according to the listing, they’re mainly for grout removal and related cleanup, and they are “not for tile cutting” (including granite hard wall).
What grout width do they suit best?
The description says they work fine with 1/8" grout lines. It also states they are not best for 1/16” grout.
Do they work on plaster mortar and thinset?
Yes, the listing specifically mentions plaster mortar, sanitary base, thinset, grit grout removal, and joint cleaning.
Is compatibility with Bosch and Dremel guaranteed?
They’re marketed as compatible with multiple brands, but the listing also names specific platforms that are not compatible. Checking your exact tool model/mount is a must.
How careful do you need to be?
The description repeatedly flags that removing grout needs care because it’s easy to damage the tile—so slow, controlled passes are part of the deal.
