Bosch PMF 220 CE Multi-X
Best OverallPros
- Versatile tool for sanding, cutting, scraping
- Effective Grout-Ex blade included
- Good balance and ergonomics
Cons
- No dust extraction port
- Blade can wear quickly on hard grout
The Bosch PMF 220 CE Multi-X is a multi-function oscillating tool that excels at grout removal when fitted with the Starlock Grout-Ex blade. Owner reviews on Amazon and DIY forums consistently praise its ability to remove old grout without damaging tiles, provided the user maintains a steady hand. The variable speed dial lets you match the oscillation rate to the grout hardness, reducing the risk of chipping.
Where this tool shines is its versatility. Once the grout removal job is done, you can swap to a sanding pad or plunge-cut blade for other projects. This makes it a better value for most DIYers compared to a single-purpose grout remover. The main drawback noted by users is the lack of a built-in dust extraction port, meaning you will need to use a shop vac hose held near the work area to control dust.
Bosch GTR 35 CE
Best Dedicated Grout RemoverPros
- Integrated dust extraction
- High power for fast removal
- Depth guide prevents tile damage
Cons
- Single-purpose tool
- Heavier than oscillating tools
The Bosch GTR 35 CE is purpose-built for grout removal and nothing else. It features a powerful 350W motor and a reciprocating blade action that removes grout faster than any oscillating tool. The standout feature is the integrated dust extraction port that connects directly to a standard shop vac, keeping the work area almost dust-free. Owner reviews highlight the depth guide as a key safety feature that prevents the blade from scratching the tile surface.
This tool is best suited for professionals or serious DIYers who have large tiling areas to re-grout. The trade-off is that it is a single-function tool, so it will sit in your toolbox after the job is done. Some users also report that the replacement blades are more expensive than standard oscillating tool blades. For a one-off bathroom renovation, the PMF 220 CE offers better value.
Bosch GOP 30-28 Starlock
Best Heavy DIYPros
- Starlock mount for quick blade changes
- Constant speed under load
- Good vibration control
Cons
- No carrying case included
- Dust extraction adapter sold separately
The Bosch GOP 30-28 is a step up from the PMF 220 CE in terms of power and build quality. It uses the Starlock mounting system, which allows for tool-free blade changes and better power transfer. Owner reviews note that the constant speed electronics keep the blade oscillating at the set speed even when pressing hard into the grout line, which prevents stalling. This makes it more efficient for removing harder cementitious grout.
Where this tool falls short for grout removal specifically is that it does not come with a dust extraction adapter in the box. You will need to purchase the Bosch GTA 500 adapter separately to connect a vacuum. The GOP 30-28 is a better overall oscillating tool than the PMF 220 CE, but for pure grout removal value, the PMF 220 CE is still the better buy for most DIYers.
Bosch GOP 40-30 Starlock
Best ProfessionalPros
- Highest power in class
- StarlockPlus for more torque
- Low vibration and quiet operation
Cons
- Expensive for occasional use
- Overkill for small jobs
The Bosch GOP 40-30 is the most powerful oscillating tool in Bosch's lineup, with a 400W motor that delivers exceptional torque. For grout removal, this means you can cut through even the hardest epoxy grout with ease. The StarlockPlus mount provides a more secure connection and allows the use of larger, more aggressive blades. Professional tilers on forums rate this tool highly for its durability and consistent performance on long jobs.
The main downside is the price point, which is significantly higher than the PMF 220 CE. For a homeowner regrouting a single bathroom, this tool is overkill. However, for a contractor who uses the tool daily for multiple tasks including grout removal, plunge cuts, and sanding, the GOP 40-30 is a worthwhile investment. It also comes with a dust extraction adapter in the box, which the GOP 30-28 does not.
Bosch PMF 180 E Multi-X
Best BudgetPros
- Lowest price in Bosch lineup
- Lightweight and easy to handle
- Includes basic grout removal blade
Cons
- Fixed speed limits control
- Less power for hard grout
The Bosch PMF 180 E is the entry-level Multi-X tool and the most affordable way to get a Bosch oscillating tool for grout removal. It has a fixed oscillation speed, which means you cannot adjust the rate for different grout types. Owner reviews suggest it works well for soft sanded grout but struggles with harder cement-based grout, requiring more passes and pressure. The lower power (180W) also means it is slower than the PMF 220 CE.
This tool is best suited for very occasional use, such as regrouting a small backsplash or a single shower. The lack of variable speed is a notable limitation, as running at full speed on delicate tiles can increase the risk of chipping. If your budget allows, the PMF 220 CE is a much better investment for only a small price increase.
What to check before buying a Bosch grout remover
Before purchasing a Bosch grout remover, consider the type of grout you need to remove. Soft sanded grout is easier to cut than hard epoxy or cementitious grout. For hard grout, a higher power tool like the GOP 40-30 or the dedicated GTR 35 CE will save significant time and effort. Also check the width of your grout lines. Most oscillating tool blades are designed for standard 2-3 mm grout lines. For wider lines, you may need a specific blade.
Dust control is another critical factor. Grout removal creates fine silica dust that is harmful to breathe. If you cannot use a vacuum, the GTR 35 CE with its integrated dust port is the best choice. For oscillating tools, look for the Bosch GTA 500 dust extraction adapter. Finally, consider the ecosystem. If you already own Bosch power tools, the Starlock mount system means you can share blades and accessories across tools.
Mistakes to avoid when using a Bosch grout remover
The most common mistake is using too much pressure. Let the tool's oscillation do the work. Pressing hard can cause the blade to overheat and wear out faster, and it increases the risk of chipping the tile edge. Always start at a lower speed setting on variable speed tools and increase as needed.
Another mistake is neglecting dust protection. Even with a vacuum, wear a N95 mask and safety glasses. Silica dust is a serious health hazard. Also avoid using the wrong blade. The Bosch Grout-Ex blade has a special carbide grit coating designed for grout. Using a standard wood-cutting blade will be ineffective and may damage the tool or tile.
Who is the Bosch grout remover for?
The Bosch PMF 220 CE Multi-X is for the DIY homeowner who wants one tool that can remove grout, sand wood, and cut drywall. It is the best balance of price, performance, and versatility. The dedicated GTR 35 CE is for the professional tiler who removes grout daily and values speed and dust control above all else. The GOP 30-28 and GOP 40-30 are for serious DIYers and pros who need a high-performance oscillating tool for multiple tasks, not just grout.
Performance and build quality
Bosch is known for reliable build quality across its power tool range. The Multi-X and GOP series tools feature robust plastic housings with rubber overmolds for grip and vibration reduction. The Starlock mount system is a significant advantage over universal mount tools, as it provides a tighter connection that reduces blade wobble and improves cutting accuracy. Owner reviews on Amazon and retailer sites consistently rate Bosch tools 4.0 out of 5 stars or higher for durability.
In terms of grout removal performance, the dedicated GTR 35 CE is the fastest, capable of removing grout at a rate of around 1 meter per minute on standard lines. The oscillating tools are slower, typically removing 30-50 cm per minute, but they offer much more control and are less likely to damage tiles. The variable speed control on the PMF 220 CE and GOP models is essential for matching the tool speed to the grout hardness.
Alternatives to consider
If you are not committed to the Bosch ecosystem, consider the DeWalt DWE315K oscillating tool, which offers similar performance to the PMF 220 CE with a universal mount. For a dedicated grout remover, the Fein RSGrout Cutter is a direct competitor to the GTR 35 CE, known for its smooth operation and dust collection. Makita also offers the TM3010CX3 oscillating tool, which is well-regarded for its ergonomics. However, Bosch's Starlock mount system gives it an advantage in blade stability and ease of use.
