What to look for when choosing the best grout removal blades for Multi-Tools.

So you got your trusty old oscillating multi-tool or maybe even purchased a new one, and are wanting to use it as a grout removal tool.

Great choice! 

I love using a multi-tool for grout removal and I have declared it the best grout removal tool many times before as it provides great user control, superior grout removal speed and is easy to use.

Of course, the multi-tool itself won’t remove grout on its own. You need a good quality grout removal blade attached to it before it will even begin to scratch the surface of your old grout.

Here are a few tips on selecting your next grout removal blade to ensure your investment works harder than you do and you get the job done in no time.

1 – Choose A Reputable Brand.

This may seem obvious but the abundance of cheap unbranded or knock-off grout removal blades will make anyone tempted to spend a few bucks less on a cheapie.

Truth is that you get what you pay for with grout removal blades as the materials used in the manufacture of the blade reflects the price.

If you want your grout remover blade to last for longer than one job then I recommend buying either Bosch or DeWalt oscillating multi-tool blades.

They are made of the highest quality material and should last you a long time before the carbide or diamond grit wears off down to the metal.

You could buy a cheap grout removal blade if you plan to use it very rarely however with the very low cost of the DeWalt DWA4242 blade, you might as well just buy it and have quality for life.

2 – Make sure it will fit your Oscillating Multi-Tool.

The last thing you want when your ready to remove some grout is to find out that your grout removal blade won’t fit your multi-tool!

I have had this happen back in the day when multi-tools were a new concept and every manufacturer had their own unique head pattern.

Nowadays the market has become smart and most brands allow intermixing between blades and tools so this shouldn’t catch you out as much.

However, I suggest you read the product page properly and look at the packaging to see what brand of multi-tools support your new grout removal blade.

The grout removing multi-tool blades from Bosch and DeWalt that I have linked offer virtually universal fitment across the various brands of multi-tools so you should be fine with whichever grout remover you choose.

A further tip!

If you own a DeWalt brand multi-tool like the ones I recommend then remember the quick attachment head. 

They make fitting various blades very easy, however, this only works on DeWalt blades as they have the specific cut-out in the rear of the blade to accommodate this.

The Bosch grout removal blades are fully enclosed and won’t work for quick attachment and you will need to fit them by unscrewing the bolt like every other multi-tool.

It’s a small thing but needs to be mentioned so you get the most out of the best grout removal tool.

3 – Choose the Right Blade for the Job

This one is important to remember so you make short work of your next grout removal task.

I talk in-depth about grout removal blades in this article if you want to read more otherwise I’ll summarise it here.

You need to take note of the shape of the grout removal blades and see if they’ll work best for your task.

Wide grout removal blades are ideal for large jobs that require a lot of grout to be removed.

The wide surface area and a large amount of diamond/carbide grit on the blade itself mean that you will get a lot more life out of your blade.

You can position your multi-tool in different positions throughout the grout removal process to use all the surface of your new blade.

Besides that, you will also tear through old grout much faster than a narrow blade as there’s simply more blade surface making contact with the grout.

Long story short: Big jobs require big blades!

Narrow blades are a MUST for grout removal jobs on the floor.

Just check out the image and you will see what I mean.

While the wide grout removal blades are great for their large jobs, their semi-round design means they can’t work near walls or vertical surfaces.

You will begin cutting into the wall before you even get close to the grout that is near it.

The solution?

Remove as much grout as you can with the wide grout remover, then change over to the narrow head blade and finish off any joints near the wall.

This saves you getting in there with a grout saw or knife and you will get a much better result as well.

If you are buying a grout removal blade to replace a tile or two then you can just buy this narrow grout blade.

Of course the drawbacks of this grout removal blade are obvious due to the small surface area working away at the grout.

You will spend more time removing grout but do not let this sway you away from buying one. The versatility and the areas it allows you to work in far outweigh the cons.

That’s it!

With those main three points taken into consideration, you should be ready to purchase your next grout removal blade for your oscillating multi-tool.

Just take a moment to read the sales page and you’ll be certain to make the right decision.

Now that you have this information fresh in your mind, scroll up and click on the grout removal blade you like the most.

It will take you to the lowest price currently available so you can make your hard earned money go further in your renovation job.

With your new grout removal blade and multi-tool, you have a grout removal tool fit for a King!
