Tile removal is one of the harshest jobs an oscillating tool handles. Grout is abrasive, the loads are continuous, and the blade torques against hard ceramic edges that want to catch and kick. Most oscillating tools can cut grout -- but the motors that bog, the blade clamps that loosen under vibration, and the tools without load compensation will make the job slower, sloppier, and harder on the adjacent tiles you are trying to keep intact.
We ran 5 oscillating tools through a complete bathroom tile removal project -- 60 square feet of ceramic floor tile, two shower niches, and a backsplash -- and measured motor temperature, speed consistency under load, blade retention, and how clean each tool left the substrate. The 4 picks below earned their place.
How We Tested
Each tool ran through 4 grout-specific tests: (1) 20 linear feet of grout cutting in ceramic floor tile at a fixed 3 oz of pressure -- we measured whether speed held or dropped; (2) 50 consecutive blade starts into hard grout to check for blade slippage or loosening; (3) a 15-minute continuous grout-cutting session to measure motor temperature at the housing; (4) a precision entry cut around a floor drain to test low-speed control. All blades used were carbide-grit grout removal blades of the same manufacturer. All tools were purchased at retail.
Grout Removal: What the Tool Actually Has to Do
Cutting grout is not like cutting wood. Wood gives -- the blade moves through it progressively. Grout is a rigid abrasive material that resists the blade constantly and heats it quickly. The oscillating tool's motor has to maintain speed against that resistance for minutes at a time, not seconds. Motors without load compensation (where speed drops under resistance) cut grout slowly and leave rough edges because the reduced oscillation speed means the carbide grit is not removing material consistently.
Blade attachment matters just as much. An oscillating tool vibrating at 20,000 oscillations per minute against grout generates a lot of force trying to rotate the blade on its mount. Blade systems that use a single round hole (older designs) transmit less of that energy to the blade and allow micro-rotation. Milwaukee's FIXTEC and Bosch's StarlockPlus use full-contact blade interfaces that lock the blade against the arbor face -- significantly less vibration, more consistent cut.
#1: Milwaukee 2626-20 M18 -- Best Overall for Tile Work
The Milwaukee 2626-20's POWERSTATE brushless motor is the standout feature for grout work. In our continuous grout-cutting test, the Milwaukee held its set speed consistently from start to finish. Competing tools showed visible speed drop under load -- you can hear it, and you can see the cut quality degrade as the RPM falls. POWERSTATE's active speed regulation keeps the motor at target regardless of load, which produces consistent grout removal and protects against the tool stalling mid-joint.
The FIXTEC blade system changes blades without a tool in under 5 seconds. For a full bathroom floor tile removal, you will change grout blades 3-5 times as the carbide grit wears. FIXTEC makes those changes fast. The tool runs on the M18 platform, which has the widest cordless ecosystem in the pro tier -- batteries power your circular saw, drill, recip saw, and vacuum off the same packs. At $99 bare, it is priced level with the DeWalt and lower than the Bosch.

#2: Bosch GOP18V-28N -- Best for Precision Tile Work
The Bosch GOP18V-28N is the right tool when vibration is the enemy. On a 12x24 large-format tile with narrow grout lines, any blade wobble risks cracking the tile you are trying to keep. The StarlockPlus blade interface contacts the arbor across the full blade face, not just through a hole -- Bosch claims 100% more power transfer vs. round-hole designs, and our testing confirmed significantly less blade vibration during the cut. KickBack Stop detects when the blade catches a tile edge and cuts motor power instantly, preventing the rotational kickback that chips adjacent tiles.
The electronic variable speed with tactile feedback holds speed precisely at whatever setting you choose. For entry cuts around floor fixtures and along baseboards, the low-speed precision of the Bosch is the best we tested. At $119 bare it is the most expensive tool in this roundup, and the StarlockPlus blades carry a premium -- budget for quality grout blades when you spec this tool.
#3: DeWalt DCS354B -- Best Value
The DeWalt DCS354B is the best choice for DeWalt 20V MAX users who need tile removal as part of a broader remodel -- not just dedicated tile work. The universal blade adapter accepts any brand's oscillating blades, which means you are not locked into DeWalt-branded grout blades. For budget buyers, that matters: third-party carbide grout blades cost half what branded blades do and perform comparably on ceramic tile. The quick-change accessory system is fast (under 6 seconds) and reliable -- no blade loosening in our 50-start test. The XR brushless motor handles grout cutting well, though it shows a slight speed drop under sustained heavy load compared to the Milwaukee's POWERSTATE.
#4: Makita XMT03Z -- Best Lightweight
The Makita XMT03Z earns its spot for homeowners who need light weight and a very low minimum speed. At its lowest setting (6,000 OPM vs. 10,000-10,500 on competitors), the Makita is the most controllable tool for entry cuts in confined spaces and careful grout work around fixtures. The weight advantage shows up after 45+ minutes of floor grout work -- less hand fatigue means cleaner cuts in the second half of the job. The LXT battery platform covers routers, circular saws, and jigsaws for the full remodel. Trade-off: the lever-style blade clamp is slower than FIXTEC, and the motor runs warmer on long continuous sessions than the Milwaukee.
How to Remove Tile with an Oscillating Tool
Step 1: Cut all grout lines first. Do not try to pop tiles before cutting grout. Use a carbide-grit grout blade set at medium speed. Work in one direction (horizontal lines first, then vertical). Keep the blade flat in the joint -- angling it risks chipping the tile face.
Step 2: Start with a corner tile. Once grout lines are cut, start at a corner where you can get a chisel or floor scraper under the tile edge. A 5-in-1 tool under the tile edge and light hammer taps breaks the tile-to-substrate bond more cleanly than prying from the center.
Step 3: Use a scraper blade to clean the substrate. After tiles are removed, switch to a rigid scraper blade on the oscillating tool to remove thinset from the substrate. Work at low speed to avoid gouging cement board or drywall. For heavy thinset, an angle grinder with a thinset removal cup wheel is faster on large areas.
Use the right blade for grout type. Sanded grout (standard floor grout, 1/8"-3/8" joints): standard carbide-grit grout blade. Unsanded grout (wall tile, narrow joints under 1/8"): narrow grout blade or a diamond oscillating blade. Epoxy grout: requires a diamond blade and patience -- epoxy grout is significantly harder than cement-based grout.

FAQ
Can an oscillating tool remove tile from a shower wall without cracking the backer board?
Yes, if you use the right technique. Cut grout first at low-to-medium speed with the blade flat in the joint -- do not angle into the tile. After tiles are freed, use a rigid scraper blade at low speed to remove thinset. The risk to cement backer board comes from aggressive prying, not from the oscillating tool itself. Keep the scraper blade parallel to the surface and take thin passes.
What blade should I use for cutting grout on ceramic tile?
A carbide-grit oscillating blade is the standard for ceramic tile grout. For narrow grout lines under 1/8", use a thin carbide blade or a bi-metal blade. Diamond-coated blades last longer (30-50x longer than carbide-grit) but cost more upfront -- they are worth it for large jobs over 50 sq ft. Avoid standard HCS or BIM blades for grout -- they wear out in minutes on abrasive cement-based material.
How long does it take to remove tile grout with an oscillating tool?
A standard bathroom (40-60 sq ft of ceramic floor tile) takes 2-4 hours with a quality oscillating tool and fresh carbide blade, working methodically. Budget 1 hour per 15-20 linear feet of grout line. Plan to change blades 3-5 times -- a dull blade doubles your time and heats up the substrate. Large format tile with wider grout joints goes faster; mosaic tile with dozens of narrow joints per square foot is slower.
Is an angle grinder or oscillating tool better for tile removal?
It depends on the scope. An oscillating tool is better for precision grout removal, working around fixtures, and protecting the substrate. An angle grinder with a diamond cup wheel removes thinset from a large substrate area much faster (5x or more), but has zero precision near walls and fixtures. For a full tile removal, use both: oscillating tool for grout cutting and edge work, angle grinder for thinset cleanup on open floor areas.
