Makita XMT03Z + A-93670 Blade
Best cordless oscillating tool for grout removal with excellent battery life.
Makita XMT03Z 18V LXT Cordless Oscillating Multi-Tool
Best Cordless ToolPros
- Excellent variable speed control for delicate grout work
- Low vibration design reduces user fatigue
- Tool-less blade change system is fast and secure
Cons
- Battery and charger sold separately
- Not the most powerful for heavy demolition
The Makita XMT03Z is the most popular cordless oscillating tool for grout removal because of its refined speed control and low vibration. It uses the 18V LXT platform, which is shared with over 300 Makita tools, meaning users already in the ecosystem can share batteries. The variable speed trigger allows precise adjustment from 6,000 to 20,000 OPM, which is ideal for the delicate work of removing grout without chipping tile edges.
Owner reviews on retailer sites consistently praise the tool's balance and runtime. With a 5.0Ah battery, users report being able to remove grout from a standard 50 sq ft bathroom floor on a single charge. The tool-less blade change lever is robust and accepts all standard oscillating tool accessories, including the Makita A-93670 grout removal blade.
Makita A-93670 Carbide-Grit Grout Removal Blade
Best BladePros
- Carbide grit lasts much longer than standard blades
- Precise 1-1/4 inch width fits standard grout lines
- Universal mount works with most oscillating tools
Cons
- Can be aggressive on soft grout if not careful
- Not ideal for removing thick mortar beds
The Makita A-93670 is a dedicated grout removal blade with a carbide-grit edge designed to cut through hardened cementitious grout without loading up. Unlike toothed blades that can grab and chip tiles, the grit edge abrades the grout away smoothly. The 1-1/4 inch width is ideal for standard 1/8 to 1/4 inch grout lines, and the universal mount fits most oscillating tools including DeWalt, Milwaukee, and Bosch.
Owner reviews highlight the blade's longevity compared to standard bi-metal blades. Users report cutting 50 to 100 linear feet of grout before noticeable wear. The blade runs cooler than toothed alternatives, reducing the risk of damaging heat-sensitive tiles. It is best used at medium speed settings (12,000-15,000 OPM) for optimal material removal and blade life.
Makita XMT03Z + A-93670 Combo Kit
Best Value KitPros
- Guaranteed compatibility between tool and blade
- Often sold at a discount compared to separate purchases
- Includes the best blade for grout removal
Cons
- Battery and charger still required separately
- Only includes one blade type
Many retailers offer the XMT03Z tool bundled with the A-93670 blade as a grout removal kit. This is the most convenient option for users who want a guaranteed match between tool and accessory. The combination is purpose-built for grout removal and eliminates any guesswork about blade compatibility or performance.
Owner reviews indicate that the kit price is typically 10-15% less than buying the tool and blade separately. The bundle is especially popular among DIYers tackling a single bathroom or kitchen renovation. Users recommend adding a second A-93670 blade to the kit for larger jobs, as the carbide grit will eventually wear down after extensive use.
Makita 18V LXT 5.0Ah Battery (BL1850B)
Best Battery for Grout WorkPros
- Long runtime for extended grout removal sessions
- Lightweight compared to 6.0Ah models
- Star Protection computer controls prevent overload
Cons
- Not compatible with older Makita 18V tools without Star Protection
- Heavier than 3.0Ah battery for short jobs
The BL1850B is the recommended battery for the XMT03Z grout remover because it balances runtime and weight. A 5.0Ah capacity provides enough power to remove grout from a typical shower enclosure on a single charge. The Star Protection system monitors battery temperature and discharge rate, which is useful during prolonged high-speed operation.
Owner reviews note that the battery lasts 45-60 minutes of continuous grout removal at medium speed. Users who already own other Makita 18V tools appreciate the cross-compatibility. For smaller jobs, a 3.0Ah battery is lighter and sufficient, but the 5.0Ah is the best all-around choice for grout work.
Makita DC18RC Rapid Charger
Best ChargerPros
- Rapid charging reduces downtime between jobs
- Active cooling fan extends battery life
- Compact design for easy storage
Cons
- Louder than standard chargers during cooling cycle
- Not compatible with 12V CXT batteries
The DC18RC is Makita's most popular rapid charger and is essential for users who need to recharge batteries quickly between grout removal sessions. It charges a 5.0Ah battery in about 45 minutes, compared to over an hour with standard chargers. The built-in cooling fan monitors battery temperature and adjusts charging speed to prevent overheating.
Owner reviews highlight the charger's reliability and durability. Many users have used the same DC18RC for years with multiple Makita tools. The LED indicators show charging status clearly, and the compact footprint makes it easy to mount on a wall or store in a toolbox.

What is the Makita Grout Remover?
The Makita grout remover is not a single dedicated tool but a system consisting of the XMT03Z oscillating multi-tool and the A-93670 carbide-grit blade. This combination is designed to remove old grout from tile joints quickly and cleanly. The oscillating action of the tool moves the blade side-to-side at high speed, abrading the grout without damaging the tile edges.
Makita offers several oscillating tools in its lineup, but the XMT03Z is the most popular for grout removal due to its variable speed trigger and low vibration. The A-93670 blade features a carbide-grit edge that is bonded to a steel backing plate, providing long life and consistent cutting performance. Together, they form a system that competes directly with dedicated grout removal tools from brands like Fein and Bosch.
Who is the Makita Grout Remover For?
The Makita grout remover system is suitable for both DIY homeowners and professional tilers. DIY users will appreciate the ease of use and the ability to remove grout without hiring a professional. The tool is lightweight and easy to control, making it accessible for bathroom and kitchen renovations.
Professional tilers and remodelers will benefit from the system's speed and reliability. The 18V LXT battery platform allows for cordless operation, which is essential on jobsites without easy access to power outlets. The low vibration design also reduces hand fatigue during extended use, which is a key consideration for professionals who use the tool daily.
Performance and Build Quality
The XMT03Z delivers consistent performance across a wide range of grout types. The variable speed trigger allows users to start slowly and increase speed as needed. At lower speeds (6,000-10,000 OPM), the tool is ideal for removing soft grout or working near delicate tiles. At higher speeds (15,000-20,000 OPM), it cuts through hardened cementitious grout efficiently.
Build quality is typical of Makita's LXT lineup. The tool features a rubberized grip for comfort, a durable aluminum housing for the gear case, and a tool-less blade change system that uses a lever rather than a screw. The A-93670 blade is made from high-quality steel with a carbide grit edge that is bonded using a proprietary process. Owner reviews on Amazon and Home Depot report that the blade lasts significantly longer than generic alternatives.
What to Check Before Buying a Makita Grout Remover
Before purchasing, ensure you have compatible batteries. The XMT03Z is a bare tool, meaning it does not include a battery or charger. If you do not already own Makita 18V LXT batteries, factor the cost of a battery and charger into your budget. The BL1850B 5.0Ah battery is recommended for grout work.
Also check the grout line width in your tile installation. The A-93670 blade is 1-1/4 inches wide, which is suitable for most standard grout lines. For wider grout lines (over 1/4 inch), consider using a different blade or making multiple passes. For very narrow lines (under 1/8 inch), the blade may be too wide and could damage adjacent tiles.
Mistakes to Avoid When Using a Grout Remover
A common mistake is using too high a speed setting. High speed generates more heat and can cause the blade to glaze over, reducing its cutting efficiency. Start at a medium speed (12,000 OPM) and adjust based on the grout hardness. Another mistake is applying too much pressure. Let the tool do the work; excessive pressure can cause the blade to bind and potentially chip tiles.
Not wearing proper PPE is another frequent error. Grout removal creates fine silica dust that is hazardous to breathe. Always wear a dust mask or respirator, safety glasses, and hearing protection. Using a vacuum attachment or wetting the grout slightly can reduce airborne dust.
