The DeWalt DWE315 is a 4.0 amp oscillating multi-tool that delivers up to 20,000 OPM. When paired with the DWASGRTR carbide grit grout removal blade, it cuts through sanded and unsanded grout efficiently. The variable speed trigger lets you adjust the pace for different grout widths and tile types.
Owner reviews on retailer sites highlight the dust extraction port as a standout feature. It connects to standard vacuum hoses and keeps airborne silica dust to a minimum. The tool-free blade change system is another frequently praised detail, making swaps quick between grout removal and other tasks.
Expert take: The DWE315 offers the best balance of power, dust control, and ease of use for DIY grout removal. The blade life is reasonable for occasional use, though heavy users may want a spare.
The Makita TM3010CX1 is a 3.0 amp oscillating tool known for its smooth operation and low vibration. It offers a speed range of 6,000 to 19,000 OPM, which provides good control for delicate grout removal near tile edges. The tool accepts universal oscillating blades, giving you flexibility in blade choice.
Professional users on forums note that the Makita maintains consistent speed under load better than some competitors. The main drawback for grout work is the lack of an integrated dust port on the base model, meaning you will need to use a separate dust collection shroud for clean operation.
Expert take: The TM3010CX1 is a premium choice for tradespeople who need reliability and low fatigue over long work sessions. The vibration dampening is genuinely noticeable.
The Milwaukee 2626-20 is a cordless M18 Fuel oscillating tool that delivers corded-level performance. The brushless motor provides up to 18,000 OPM and maintains speed well under load. For grout removal, this means consistent cutting through hard sanded grout without bogging down.
User reviews consistently praise the runtime, with a 5.0Ah battery lasting through multiple bathroom walls of grout removal. The tool is slightly heavier than corded alternatives due to the battery, but the freedom of movement is a significant advantage for overhead or awkward angle work.
Expert take: If you already own M18 batteries, this is the most convenient grout removal tool. The power is comparable to corded units, and the battery platform is widely available.
The Bosch GOP40-30 features a 4.2 amp motor that provides ample power for grout removal. The speed control dial allows precise adjustments between 8,000 and 20,000 OPM, which is useful when working near delicate tile edges. The tool is known for its relatively quiet operation compared to other oscillating tools.
Owner feedback indicates the tool performs well for detailed work, but the blade change system requires a hex key rather than the tool-free systems found on DeWalt and Makita models. The dust port is not included with the base tool, which is a notable omission for grout work where silica dust is a concern.
Expert take: The GOP40-30 is a strong performer for users who prioritize power and precision over quick blade changes. It is best suited for controlled, careful grout removal.
The Ryobi P45111 is an 18V cordless oscillating tool that works with the extensive ONE+ battery system. It offers speeds from 10,000 to 17,000 OPM, which is sufficient for standard grout lines but may struggle with thicker joints. The tool features a tool-free blade change system for convenience.
Budget-conscious DIYers on forums appreciate the low cost and battery compatibility. However, reviews note that the tool has less power than corded models and may bog down on hard sanded grout. It is best suited for occasional use on small bathroom or kitchen tile projects.
Expert take: The P45111 is a solid choice for homeowners who already own Ryobi ONE+ batteries and need an occasional grout removal tool. It is not built for heavy daily use.
The DeWalt DWE315 with the DWASGRTR blade is designed for DIYers and semi-professional users who need a reliable grout removal solution. It works well for removing old grout from bathroom walls, kitchen backsplashes, and floor tiles. The variable speed trigger makes it suitable for both beginners and experienced users who want control over the cutting action.
Performance and Build Quality
The DWE315 features a 4.0 amp motor that delivers up to 20,000 OPM. This power level is sufficient for cutting through sanded grout and unsanded grout. The carbide grit blade is designed specifically for grout removal and lasts through multiple projects before needing replacement. Owner reviews on retailer sites rate the tool highly for its consistent performance and low vibration levels.
Build quality is typical of DeWalt tools: durable housing, rubber overmold grip, and reliable electronics. The dust extraction port is a practical addition that connects to standard shop vac hoses. This feature is frequently mentioned in positive reviews as it significantly reduces cleanup time.
What to Check Before Buying a Grout Removal Tool
Before purchasing a grout removal tool, consider the type of grout you need to remove. Sanded grout is harder and requires more power and a carbide blade. Unsanded grout is softer and can be removed with less aggressive blades. Check the width of your grout lines as wider joints may require a larger blade or slower speed.
Also consider whether you prefer corded or cordless operation. Corded tools offer unlimited runtime and consistent power, while cordless tools provide mobility for tight spaces. If you already own a battery platform from a major brand, a cordless tool from that ecosystem may be the most cost-effective choice.
Mistakes to Avoid When Removing Grout
One common mistake is using too much pressure. Oscillating tools work best with light pressure and consistent motion. Pushing harder does not speed up the process and can damage the blade or the tile edge. Another mistake is neglecting dust control. Grout contains silica dust, which is harmful to lungs. Always use a dust extraction system or wear a proper respirator.
Avoid using the wrong blade type. Standard wood or metal cutting blades are not designed for grout and will wear out quickly or damage tiles. Always use a carbide grit blade specifically designed for grout removal. Finally, do not rush the process. Removing grout is a slow, methodical task that requires patience to avoid damaging surrounding tiles.
FAQs
Can I use a regular oscillating blade for grout removal?
No, standard blades are not designed for masonry materials. Use a carbide grit blade specifically made for grout removal to avoid damaging tiles and the blade.
How long does a DeWalt grout removal blade last?
Blade life depends on the type and amount of grout. For a standard bathroom, a single blade typically lasts through one full project of removing old grout.
Is the DeWalt DWE315 compatible with other brand blades?
Yes, the DWE315 accepts universal oscillating tool blades from other brands, including Makita and Bosch, as long as they use the standard OIS mount.
Do I need a dust extractor for grout removal?
Yes, grout contains crystalline silica which is hazardous when inhaled. A dust extractor with a HEPA filter is strongly recommended for any grout removal work.
Can I remove grout without damaging tiles?
Yes, with careful technique and the correct blade. Use light pressure and keep the tool moving. Avoid digging into the tile edges by working at a shallow angle.
What is the difference between sanded and unsanded grout?
Sanded grout contains fine sand particles for strength and is used for wider joints. Unsanded grout is smoother and used for narrow joints. Sanded grout is harder to remove.
How do I know when to replace the grout removal blade?
When the blade stops cutting efficiently and you need to apply more pressure, it is time to replace it. A worn blade will also produce more dust and heat.
Is a cordless grout remover powerful enough?
Yes, modern cordless tools like the Milwaukee M18 Fuel provide comparable power to corded models. However, battery life may be a limitation for large projects.
Can I use the DeWalt DWE315 for other tasks?
Yes, the DWE315 is a multi-tool that accepts blades for cutting wood, metal, drywall, and sanding. It is a versatile tool for many renovation tasks.
What safety gear do I need for grout removal?
Always wear safety glasses, a dust mask or respirator, and hearing protection. Gloves are also recommended to protect your hands from vibration and debris.
Our verdict
The DeWalt DWE315 with the DWASGRTR blade is the best overall grout removal system for its power, dust control, and ease of use. For budget-conscious DIYers, the Ryobi P45111 offers a capable cordless option at a lower price point, especially if you already own ONE+ batteries.
