There are a few differences between M18 and M12 tools, however, one of the key differences lies within the Power and Performance of the tools for example:

• Milwaukee M18 tools is the more powerful platform. M18 tools are ideal for heavy-duty applications, driving larger screws, drilling tougher materials, and handling high-torque tasks.
• M12 offers a good balance between power and portability. These tools are well-suited for lighter tasks like furniture assembly, cabinetry work, and everyday DIY projects.

Size and Weight:

• M18: M18 tools are generally bigger and heavier due to their more powerful motors and larger batteries. This can be a disadvantage for tight spaces or overhead work.
• M12: Much lighter and more compact than M18 tools, M12 excels in situations where manoeuvrability and ease of use are crucial. Their smaller size allows for better control and handling in confined areas.

Battery Life:

• M18: With larger batteries, M18 tools tend to have longer run times on a single charge. This is beneficial for extended projects or continuous use.
• M12: While the battery life may be shorter than M18, M12 batteries recharge faster due to their smaller size. Additionally, the lighter weight of the tools often translates to less fatigue and potentially more work accomplished within a single battery charge.

Applications:

• M18: Construction workers, mechanics, serious DIYers, and professionals who need heavy-duty power will find M18 most suitable.
• M12: Carpenters, electricians, hobbyists, and anyone who prioritizes portability and comfortable use in tight spaces will benefit from M12’s size and weight advantage.

There are a few differences between M18 and M18 FUEL tools, however, one of the key differences lies within the motors of the tools.

M18 tools typically use brushed motors. Brushed can sometimes be considered less powerful compared to brushless motors. M18 FUEL tools come equipped with brushless motors. Brushless motors rely on electronic controls instead of brushes, offering several advantages, including:

• More power and efficiency: Brushless motors generate more power and consume less battery, allowing you to work for longer durations.
• Durability: Without components that wear out like brushes, brushless motors generally last longer.
• Reduced heat: Brushless motors generate less heat, keeping the tool cooler and potentially extending its lifespan.
• Better control: Brushless motors may provide more precise speed control for certain tasks.

Here’s a breakdown of some additional factors to consider:

RedLink Plus Technology: M18 FUEL tools often integrate Milwaukee’s RedLink Plus technology. This system uses advanced communication between batteries and tools to provide features like overload protection, extended tool life, and optimized performance.

M18 High Output Batteries: While both M18 and M18 FUEL tools work with regular M18 batteries, M18 FUEL tools can leverage the extra power of M18 High Output batteries more effectively.

In essence, M18 FUEL represents Milwaukee’s higher-performance line within their M18 platform. If you prioritize affordability and light-duty tasks, M18 tools will suit you perfectly. But, for more demanding applications, M18 FUEL’s superior power, durability, and features may make it a better choice. Milwaukee now has over 200 power tools in their M18 or 18V range, with many tool types replicated to offer different levels of performance and capability to the user. Because of the volume of M18 tools available, it can be quite overwhelming when it comes to selecting the right tool, to help with this we have put together an article to highlight the Top 10 Milwaukee 18V power tools and help guide you in choosing the best tools for the job.

Milwaukee ONE-KEY is a free-to-use cloud-based application, that provides a digital eye on all your tool inventory and users, allowing you to pinpoint missing tools quickly. This enables you to monitor your tools on-site so you can see who was last using the tool and where it’s located, saving you time and any unwanted stress during the day. It can be used via Bluetooth connectivity on smartphones, computers, and iPads allowing you to track anytime, anywhere.

With ONE-KEY, you can increase productivity and decrease downtime by assigning tools to specific people and places for added accountability at the project level. It is also fully customisable for each individual tool. For example, you can wirelessly sync your drills and impact drivers to program custom speed and torque settings directly, no longer must you personally oversee every tool whilst in use, simply check the settings via the app.

Milwaukee’s ONE-KEY technology is currently available in M18, and there are a small number of M12 tools. However, in the future, they will be expanding ONE-KEY across a larger range of tools.

Yes, many Milwaukee ONE-KEY tools allow you to adjust torque. The ONE-KEY mobile app can also adjust other settings in the field, such as maximum speed, bolt removal speed, and trigger ramp up time.

Using a Milwaukee FUEL battery on a standard M18 tool is generally safe and will likely provide increased runtime. However, you might not see the full power potential of the FUEL battery unless it's paired with a FUEL tool.
