Milwaukee M18 FUEL 2626-20
Best OverallPros
- Highest power in class
- Excellent vibration control
- Tool-free blade change
Cons
- Heavier than M12 models
- Tool-only, no battery included
The M18 FUEL 2626-20 is Milwaukee's flagship oscillating tool. It features a POWERSTATE brushless motor that delivers up to 20,000 OPM, making it ideal for cutting through nails, hardwood, and drywall. Owner reviews consistently highlight its smooth operation and lack of vibration, even during extended use.
This tool uses the M18 battery platform, which is shared across Milwaukee's heavy-duty lineup. The quick-change accessory system allows for fast blade swaps without any tools. It is a bare tool, so you will need an existing M18 battery and charger to use it.
Milwaukee M12 2426-20
Best CompactPros
- Very lightweight and compact
- Good power for size
- Tool-free blade change
Cons
- Less power than M18 FUEL
- Smaller battery platform
The M12 2426-20 is the go-to choice for tight spaces and overhead work. It weighs just 2.4 pounds with a battery, making it much easier to handle than its M18 counterparts. Despite its size, it still delivers 18,000 OPM, which is sufficient for most DIY and light professional tasks.
Users praise its balance and ergonomics. The M12 battery system is lighter and more compact, which is a major advantage for extended use. It uses the same quick-change accessory system as the M18 models, so blades are interchangeable.
Milwaukee M18 2425-20
Best BudgetPros
- Lower price point
- Compatible with M18 batteries
- Solid build quality
Cons
- Brushed motor less efficient
- Heavier and more vibration
The M18 2425-20 is the entry-level Milwaukee oscillating tool. It uses a brushed motor, which makes it less powerful and less efficient than the brushless FUEL models, but it is significantly more affordable. It still delivers 18,000 OPM, which is enough for cutting drywall, PVC, and softwoods.
Owner reviews note that it is a good tool for occasional use or for those on a tight budget. It shares the same M18 battery platform as the higher-end models, so batteries are interchangeable. The main trade-off is increased vibration and noise compared to the FUEL version.
Milwaukee M12 2426-21X
Best M12 KitPros
- Comes with batteries and charger
- Compact and lightweight
- Great for starting M12 system
Cons
- Batteries are small capacity
- Not as powerful as M18 FUEL
The M12 2426-21X is the kit version of the M12 2426-20. It includes two 2.0Ah M12 batteries and a charger, making it a perfect starter kit for those new to the M12 platform. The tool itself is identical to the bare tool version, offering the same 18,000 OPM and compact design.
Users appreciate the value of the kit, as it provides everything needed to get started. The 2.0Ah batteries are fine for light to medium tasks, but heavy users may want to upgrade to higher capacity batteries. The kit is a popular choice for electricians and maintenance workers.
Milwaukee M18 FUEL 2626-21
Best M18 KitPros
- Top-tier power and performance
- Includes high-capacity battery
- Excellent vibration control
Cons
- Higher price than bare tool
- Heavier than M12 kits
The M18 FUEL 2626-21 is the kit version of the best overall pick. It includes one 5.0Ah M18 battery and a charger, providing ample runtime for heavy-duty tasks. The tool itself is the same powerful 2626-20, with 20,000 OPM and superior vibration dampening.
This kit is ideal for professionals who need maximum performance and do not want to purchase batteries separately. The 5.0Ah battery offers a good balance of power and weight. Owner reviews rate it highly for its ability to handle tough cuts without bogging down.
What to check before buying a Milwaukee oscillating multi tool
Consider your existing battery platform first. If you already own M18 tools, the M18 models are the logical choice. If you prefer lighter tools, the M12 platform is more compact. The power difference between 18,000 and 20,000 OPM is noticeable on tough materials like hardwood and nails.
Check the accessory system. All Milwaukee oscillating tools use a universal quick-change system, but the FUEL models have a more robust locking mechanism. Also consider the vibration control, which is significantly better on the M18 FUEL models, reducing fatigue during long jobs.
Mistakes to avoid
Do not buy a brushed model (2425-20) if you plan to use the tool daily. The brushed motor is less efficient and has a shorter lifespan. Also, avoid buying a bare tool if you do not already own compatible batteries and a charger, as the initial cost can be higher than a kit.
Do not overlook the M12 platform for light work. Many users buy the M18 FUEL for heavy tasks but find it too heavy for overhead work. The M12 is a better choice for those applications. Finally, do not ignore the importance of blade quality; a good blade makes a significant difference in cut quality and speed.
