Best Grout Removal Tools of 2026

The first joint tells you what a grout blade is worth. A dull one skates across the surface and polishes the grout instead of cutting it; this DEWALT bites on contact and leaves a clean channel behind it. That's the carbide edging doing the work, and it's what makes the blade worth fitting before you've finished the first tile.

If you already own an oscillating multi-tool, this is the blade to buy. It fits every major brand without an adapter, so there's no spacer to lose, and it cuts old floor grout fast enough that a bathroom stops feeling like a punishment. It costs more per blade than the import multi-packs and earns the difference back on the first tile.

Where it gives trouble is the mount, not the grit. The carbide edging holds up well; the slotted end that makes the blade fit everything can also let it work loose in a clamp that doesn't close all the way. Seat it flat, check it after the first few passes, and don't overtighten the tool.

Buy a spare with the first blade. Old sanded grout is abrasive by design, and a blade that quits halfway through a floor costs more in lost time than a spare does in money. For a repair behind a sink, one is plenty; for a whole floor, keep a second in the drawer.

One-sixteenth of an inch is the whole argument for this blade. At that thickness it drops into narrow grout lines that a wider blade rides over, and it takes out the joint without widening it into something new grout can't fill. If your tile was set tight, this is the shape to buy.

It's rated to run at the top of a multi-tool's speed range — 21,000 oscillations per minute — and the carbide edge is happiest when you let it. Low speed with heavy pressure is how these blades die; light passes at full speed cut cleaner and keep the edge longer. The universal quick-fit interface covers Dremel, Bosch, Makita, Milwaukee and Rockwell, though a clamp on some tools grips it less firmly than a brand-matched blade does.

For thin joints, this is the blade we pick over the DEWALT. It costs more per blade than the import sets, and what you get for that is a 1/16-inch kerf matched here only by the EZARC three-pack, plus an edge that keeps working past the first wall. On a job this tedious, that's worth more than the difference. Fit it to a tool whose clamp is snug and it's the least frustrating way to open a tight grout line.

Twenty blades in one box is a strategy, not a gimmick. At about 2.3 mm these are sized for 1/8-inch joints, and the idea is that you swap a dulled blade for a fresh one instead of leaning on a tired edge and burning the tile faces with it. If your grout lines are wide, that math works.

We reach for the twenty-pack on whole floors. One diamond blade won't clear a room — the grit on the leading edge goes before the rest of the blade does — and having nineteen more in the box turns that from a problem into a rhythm: cut, swap, cut. A blade you're happy to throw away beats a blade you're afraid to use up.

Two things to check before ordering. These are specified for 1/8-inch grout, not the 1/16-inch lines the thin blades cover, so they won't drop into a tight joint. And the fit list excludes several Bosch and Dremel models unless the included adapter is used, so match the blade to your tool first. Off the grout line, they're also useful for thinset, mortar and plaster cleanup — worth knowing if you're fixing a botched tile job rather than re-grouting one.

We keep this saw for the places a powered blade can't go: the last inch against a wall, the inside corner behind a toilet, the joint under a cabinet toe kick. The angled head drops into a grout line at an angle a multi-tool can't hold, and the 8-inch handle keeps your knuckles off the tile instead of scraping them along it.

Two screws hold each blade, so a swap is a screwdriver job rather than a trip to the store, and the pack arrives with three spares — enough that you finish the job on the original tool. The toothed steel blade shaves and scrapes rather than grinding, which is why it suits grout that's already failing.

It's the wrong tool for sound, hard grout, where the teeth skate and you end up leaning on the handle with nothing to show for it. On polished tile, keep the blade inside the joint — the tooth line will mark a glaze if you let it wander across the face. Short strokes, blade in the groove, and let the teeth do the cutting.

Three tip widths on one scraper sounds like a marketing line until you hit a room where the grout line changes width between the floor and the wall. The fine, medium and large points let you match the joint instead of forcing one tip into all of it, and the head carries eight scraping edges, so there's another one ready when the first dulls.

At 13 inches, the shaft reaches the back of a shower or under a lip where a short scraper gives out, and the soft grip is shaped for pushing rather than squeezing. What it asks in return is effort. This is a hand tool, and hard grout comes out at the speed of your arm — anyone with grip trouble should look at the powered blades first.

Tungsten steel is hard, hard enough that a slip across a glazed tile leaves a mark, and brittle enough that levering sideways can snap the point. Scrape along the joint instead of prying with it and it becomes the tool that opens lines too narrow or too deep for a blade. On the awkward joints where the multi-tool has run out of reach, this is what we pick up next.

A triangular carbide tip does something a flat blade can't: it gets into the corner where two grout lines meet and turns the grout out instead of pushing it further down the joint. That's the reason to own one, and the reason it earns drawer space even when the multi-tool is already out.

The flat edge and sharp corner are backed by a fine groove ground into the tip, which keeps the point tracking in the joint rather than skating across the glaze. The rod is carbon steel, the handle is a soft-grip shape under five inches long, and the whole tool measures 9.65 inches — long enough to reach across a floor tile, short enough to control in a corner.

A spare tip comes in the box, and the tip is the part that wears. Replace it rather than the tool and the scraper keeps going long after the first point rounds over, which separates it from the one-piece scrapers that are finished when the point is.

Where it earns its keep is detail work: thinset specks in a joint you're about to re-grout, old silicone at the tub edge, mortar smeared on a tile face, the corner of a shower niche. It isn't a whole-floor tool and it doesn't try to be — but as the finishing pass after a powered blade has run the length of the room, it beats loading another blade.

The least expensive tool here is also the one that handles a job the blades can't: hooked steel teeth that pull loose caulk, putty and crumbling grout out of a joint with no power tool and no cloud of dust. If the grout you're removing is already failing rather than solid, this is the tool we suggest first.

It's carbon steel in a polypropylene handle with a soft, nonslip grip, 8.5 inches overall, and the tooth sits at an angle that lets you pull toward yourself rather than push away. The point isn't delicate. If it rounds over, a few passes on a grinding wheel bring it back, which is not something you can do with a grit-edged blade.

It won't touch sound grout, and that's the limit worth knowing before you buy: on hard, intact joints you'll work harder for less. For a tub surround's worth of old caulk, a few cracked joints, or putty around a window, it does the job and leaves nothing to clean up but a sweep.

Two blades from the same pack can behave like different tools. One walks through a grout line in smooth rocking passes; the next stalls, bounces, and leaves you pressing harder for the same cut. The variable is the diamond grit on the leading edge and how much of it is still there.

The kerf is the reason to buy them: about 1/16 inch, thin enough to drop into a tight joint and to make a flush cut against a wall or a cabinet edge. Two adapters come in the pack for tools that need them, and the blades seat without wobble in the common quick-release mounts.

Longevity is where they're uneven. The grit is a thin layer on the front edge, and once it's gone the blade is a smooth piece of steel. One blade clears a whole joint and the next quits early — the same story at a different point on the curve. That's an argument for the three-pack, not against it: treat them as consumables and the math works.

We like these for the narrow kerf and the flush cut, and we like the three-pack because it assumes the blades will die. What we don't like is not knowing which of the three is going to be the good one. For a small repair in a tight joint that's a fair trade; on a floor, the inconsistency turns into a rhythm of swapping blades, which is exactly what a bigger pack is for.
