Cuts a variety of jobsite materials quickly and accurately
Mechanical, electrical, plumbing and general construction professionals constantly fabricate channel, bar stock, conduit and other building materials for custom-sized components. That takes many repetitive short cuts where a cordless multi-purpose metal cutter can excel in speed, portability and accuracy. The EY4542LR2M metal cutting kit and tool-only EY4542XM models use one of five 5-3/8”-diameter special-purpose blades designed to slice through common metal, wood, plastic and PVC building materials. The compact tool’s no-load 3,600-rpm speed has the power to cleanly cut through materials. At only 5.84 lbs., including battery, the tool is easy to handle in a variety of cutting positions. The tool’s inline cutting design is comfortable to use and an LED light illuminates the work area to make the cutting line easier to see. A transparent window in the blade guard makes seeing the cutline easy and helps control wood or plastic dust or metal filings. The three-way guard controls dust with an attached vacuum, attached dust case or an ejector that directs dust out the rear of the tool. Its maximum 1-13/16” cutting depth is easy to adjust to match blade contact area with the work piece for fast, accurate cuts. An electric brake stops the blade quickly once the trigger is released; a safety switch lock helps prevent unintended tool start-ups. The 13/16” arbor has a shaft lock button that makes blade changes simple.
Tough and long-lasting battery packs
The tool, powered by Panasonic’s exclusive 14.4-volt 3.3Ah LR Li-ion battery pack, is built for heavy use, long runtimes between charges and long cycle life. The tool can run for 50 minutes per battery charge. Unlike manganese-based Li-ion batteries used in many cordless power tools, Panasonic’s exclusive cobalt Li-ion battery technology produces less internal heat buildup that can kill battery packs. The battery packs also feature Panasonic’s Solid Solution technology, a proprietary process for dissolving and hardening cobalt and nickel and other key battery components. This unique chemistry dramatically improves battery pack safety, reliability and power output. A special heat-resistant ceramic coating layer separates cells and protects them from heat buildup. Together, the chemistry, battery design and manufacturing process add up to powerful batteries that promise to deliver long running lives.
Battery packs that are smart, too
Sometimes professional users are their own tool’s worst enemy, attempting to push them past their design limits. This can lead to irreversible battery or tool damage. That’s why Panasonic 3.3Ah LR battery pack cells are independently monitored for even discharge while preventing over-charging and over-discharging. An over-discharge sensor prevents the user from running the tool after it reaches the point where too-low voltage output could damage the battery and the tool. Plus, an internal temperature sensor flashes a warning light if internal temperatures rise, and then cuts off tool power if battery temperature reaches critical levels. Water getting into the battery doesn’t have to mean it’s a goner. Panasonic engineers have added vents built in the battery case so water can easily drain out of the battery pack. The battery, which is easy to remove using a simple slide-down release button, can charge to 80 percent capacity in 50 minutes and fully charge in 65 minutes when charged with the EY0L81B charger. This charger comes with the EY4542LR2M kit that includes the tool, two 3.3Ah Li-ion battery packs and carrying case.
Tough tools for tough conditions
The EY7546LR2S ¼” hex cordless impact driver kit has an IP56 rating that proves the tool’s toughness claims. This rating means the tool has withstood demanding laboratory tests of working in extremely dusty work environments and the effects of water getting sprayed on the tool by powerful jets. In the field, it assures professional tradesmen have a tool that can stand up to the rigors of hard jobsite use. The IP rating is established by the International Electrotechnical Commission (IEC) and is outlined in IEC 60529. The standard outlines a coding system that indicates the degree of protection an electrical machine’s enclosure offers internal components. Based on objective testing, it assigns a rating to the enclosure’s ability to keep potentially damaging solid foreign objects (dust and contaminants) and water out of the tool under increasingly difficult conditions. The dust protection test subjects the tool to a very dusty environment and then puts it to work to assure the tool was unaffected by dust exposure. In the grueling test, the tool proved that it achieved a dust protection level of five out of six levels; the sixth level is for dust-tight tools. It’s a good indication that the tool’s design keeps potentially harmful contaminants out, assuring long life and top performance that professionals demand. Similarly, the water protection test put the tool up against increasing levels of water exposure. It attained a six out of eight levels rating, withstanding the effects of powerful water jets. Whether it’s extremely dust work conditions or work in damp or wet locations, users will appreciate a tool that will keep working when others would likely fail.

The kit comes standard with Panasonic’s EY9M13C metal-cutting blade with 30 C6 tungsten-carbide tipped teeth and .16” kerf. An optional thin-metal cutting blade, EY9PM13D, features 50 C6 tungsten-carbide tipped teeth and 1/16” kerf. Two wood-cutting blades are available: the 30-tooth EY9W13A C6-tungsten carbide-tipped blade for general wood cutting and the 48-tooth EY9PW13B blade for thin wood-cutting jobs. Both blades have a 3/64” kerf that provides straight cuts yet minimal drag on the tool. To cut plastic, the EY9PP13B blade has 52 C6 tungsten-carbide tipped teeth and a 3/64” kerf for fast, even and accurate cuts.
