Discussing the Evolution of Battery-Powered Hand Tools with the Experts at Milwaukee Tools

While battery-powered off-highway machinery like mini excavators and skid steers are just arriving on American jobsites, the power tool sector has been a proving ground for electrification for decades. Battery-powered hand tools are not the novelty that electric earthmoving machines currently are. In fact, electric power tools are rapidly becoming the standard in American toolboxes. This evolution is driven by technological advancements and an increased demand for efficiency, portability and sustainability.

“Certain regions are certainly witnessing a surge in sales of battery-powered equipment, driven by factors such as environmental regulations, incentives for green construction practices and a focus on reducing carbon emissions,” explains Brandon Fredricks, senior product manager at Milwaukee Tool. “Professionals are increasingly gravitating towards versatile battery-powered tools that offer portability without sacrificing performance, and we’re still seeing evolutions in the market, including the integration of smart battery-powered tools.”

Founded in 1924, Milwaukee Tool has a long history with electric tooling. In fact, the company was first called Milwaukee Electric Tool Corp. Milwaukee first introduced battery-powered hand tools in the 1990s. At first it offered an extensive lineup of 18-volt contractor cordless tools, all of which could be powered using the same battery and charger system. Milwaukee innovated further with the introduction of its RedLithium batteries in 2010. Then there was the creation of its M18 Fuel lineup in 2012. This took Milwaukee’s electric vision even further by delivering highly advanced battery, electronic and brushless motor capabilities. Today Milwaukee offers a whopping 425+ battery-powered cordless tools between its M12 (150+), M18 (250+) and MX Fuel (25+) systems. The MX Fuel Equipment system (popular for our audience) is specifically focused towards bigger battery-powered trade equipment. This includes everything from lighting to compaction.

The MF Fuel System

“The MX Fuel System is compatible with all MX Fuel battery packs, which provide instant power with no gas headaches,” says Fredricks. “Safer and more productive than gas or corded equipment, this innovative system decreases safety concerns from the exposure to emissions and tripping hazards, without sacrificing the performance needed to get the job done.”

The MX Fuel System, powered by lithium-ion batteries, was introduced in 2019. While Milwaukee’s M12 and M18 Fuel line mainly consists of compact and sub-compact power tools like grinders, drills/drivers and rotary tools, the MX Fuel System supports larger trade power tools like light towers, core drills, jackhammers, trowels, compaction plates and concrete saws.

Popular Markets and Applications

• General Contractors: Electric hand tools offer versatility and convenience, making them suitable for a wide range of construction projects.
• Indoor Applications: Electric hand tools are ideal for indoor projects where emissions, noise and vibration are significant concerns. This includes renovations, remodels and interior finishing work.
• Low Noise Environments: Electric hand tools are favored in environments where noise levels need to be minimized. This includes hospitals, schools and residential areas.
• Demolition: Electric demolition tools provide powerful and efficient alternatives to traditional gas-powered equipment, reducing emissions and noise levels.
• Concrete: Electric tools are increasingly used for concrete applications, delivering precision and performance without the noise and fumes associated with gas-powered equipment.
• Confined Spaces: Electric hand tools are able to operate in confined spaces and enclosed environments. This is where emissions and noise levels pose significant challenges.

Better Batteries, Cooler Tech, Better Performance

Today’s lithium-ion batteries offer significant improvements over their predecessors, providing higher energy density, longer life spans and faster charging times. Unlike older nickel-cadmium batteries, which suffered from memory effects and limited run times, lithium-ion batteries deliver consistent power and have minimal self-discharge. This advancement means that contractors can now rely on battery-powered tools to deliver the same performance as their corded counterparts. This is without the limitations of cord length and power source dependency. It feels like each year manufacturers come out with cooler battery tech.

“Milwaukee recently introduced our M18 and MX Fuel RedLithium Forge batteries, boasting enhanced performance and productivity,” says Fredricks. “These batteries feature innovative cell technology, construction and electronics, making them the most powerful, fastest-charging and longest-lasting in Milwaukee’s lineup. Paired with the new Super Chargers, they offer significantly faster charge times and high-speed cooling for reduced downtime. The built-in Redlink Intelligence protects batteries from overheating, ensuring longevity and performance.”

Innovations such as brushless motors enhance efficiency and extend battery life, ensuring that tools operate smoothly and efficiently.

“Electrification in hand tools also serves as a gateway for integrating cutting-edge technologies that enhance both usability and performance,” notes Fredricks. “A prime example is Milwaukee Tool’s M18 Fuel 1/2-in. Hammer Drill/Driver featuring Auto-Stop Control Mode. By leveraging machine learning algorithms, this groundbreaking technology swiftly detects potential bind-up events during drilling, promptly halting the tool’s operation to minimize risks.”

Portability, Productivity and Safety of Battery-Powered Hand Tools

Portability is another significant advantage of battery-powered hand tools. These tools are typically lighter and more compact than their corded or gas counterparts. This makes them easier to handle and transport. Additionally, the convenience of quick battery swaps and fast charging means that contractors can minimize downtime. There are also a variety of charging systems on the market.

“One of the cornerstones of our charging ecosystem is the Super Charger, designed to fully unlock the potential of our RedLithium Forge batteries,” says Fredricks. “The Super Charger minimizes downtime by delivering high-speed cooling from battery to charger, ensuring that users can get back to work without delay.”

For contractors who work on various jobsites, the ability to easily carry and store tools can be a game-changer. Battery-powered tools reduce the hassle of dealing with tangled cords. They also reduce searching for power outlets, streamlining workflow and reducing setup time.

“For contractors considering the transition to electric hand tools, it’s crucial to recognize the broader industry trends driving this shift towards cordless jobsites,” says Fredricks. “As you evaluate electric hand tools, look for features that prioritize jobsite safety and efficiency. Consider factors such as vibration reduction, noise control and improved dust management.”

As the construction industry increasingly focuses on sustainability, battery-powered tools align well with these environmental goals. They produce zero emissions during operation, contributing to a cleaner and healthier jobsite. Additionally, the energy efficiency of lithium-ion batteries means that less energy is wasted, further reducing the environmental impact. From a cost perspective, battery-powered tools offer long-term savings. While the initial investment may be higher compared to corded or gas tools, the reduction in maintenance costs and the absence of recurring expenses will make them pay off in the end.

The Future of Battery-Powered Hand Tools

Ongoing advancements in battery technology include the development of higher-capacity batteries and faster charging solutions. This will continue to enhance the performance and reliability of these tools. Additionally, the integration of smart technology and connectivity features is likely to become more prevalent. This offers contractors valuable data and insights to optimize their tool usage and maintenance. As battery-powered hand tools become more sophisticated and widely adopted, they will undoubtedly play a crucial role in shaping the future of the construction industry.
