Milwaukee® Delivers the Lightest, Most Compact Cordless 3/8” Crown Stapler

MILWAUKEE, WI- Milwaukee Tool expands the largest sub-compact system in the industry, the M12™ platform, with the introduction of the new M12™ 3/8” Crown Stapler. Designed to be the most ergonomic and compact cordless 3/8” crown (T50® Style) stapler, the M12™ Stapler requires 80% less muscle effort than hand tools and is up to 35% lighter than competitors’ cordless staplers. With the ability to fire 1500 staples on one battery, the new stapler provides the superior performance of a power tool, with the all of the benefits of hand tool portability. “Manual staplers are used for a variety of applications across a number of different trades, from the installation of insulation and polyethylene vapor barrier to the installation of Thermo-Pan® sheeting for return air ducts. The repetitive motion and excessive force required to operate these staplers translates to considerable fatigue and can even cause injury to a user after years of use. Unfortunately, the powered solutions currently available are either too bulky, underpowered, or require the user to wrestle with cords,” said Tyson Apfelbeck, Senior Product Manager for Milwaukee Tool. “The M12™ 3/8” Crown Stapler provides performance and run-time that rivals the leading cordless solution, at a fraction of the size and weight, and requires much less muscle effort to operate.”

At only 3.5 lbs. with battery, 7-1/4” in length, and just over 1-1/2” wide at the nose, the M12™ 3/8” Crown Stapler allows easy access into corners and tight spaces. For added utility, because of its compact size, the Stapler can be comfortably worn on a tool belt – something unheard of with other cordless and corded staplers. Able to operate in either bump fire or sequential fire, and capable of firing up to 1500 3/8” crown (T50® Style) staples on a single 1.5Ah battery pack, the stapler will greatly reduce downtime and maximize productivity. Staple leg locating arrows allow the user to see exactly where the staple legs are leaving the tool, providing increased accuracy. These features, coupled with the stapler’s balanced and ergonomic design, means the user will experience a better feel and overall performance than competitive tools on the market today.

Available in October of 2017, the new M12™ 3/8” Crown Stapler is compatible with the entire M12™ System, now offering more than 70 professional cordless solutions focused on power, productivity, and portability.
