Original Press Release:

Milwaukee's Hammers are Hard Hitting and Big on Performance

Brookfield, WI - Milwaukee Electric Tool Corporation introduces four new Rotary/ Demolition Hammers with 19.9 ft-lbs of blow energy, an in-line design and user friendly features that make tool use less taxing on the operator. The models are ideal for drilling large holes for pipe or conduit, demolition work, driving ground rods, scraping splatter and adhesives, removing tile, digging in hard or frozen ground, tamping small areas or bushing surfaces before new surface applications.

The new models - 5337-21 3/4" hex demolition hammer, 5340-21 2" spline rotary hammer, 5339-21 SDS-Max demolition hammer and 5342-21 2" SDS-Max rotary hammer - offer high blow force for fast demolition and efficient drilling. The exclusive Vibration Isolation System and in-line design reduce worker fatigue. The tools have vibration reducing materials and a floating-action switch handle that cuts vibration to the user. The handle can be mounted left, right or at the rear of the tool to comfortably match the application.

Because these tools are often used on ground-level jobs, when the handle is mounted in the rear position it makes these tools much more comfortable to operate because users don't have to bend or hunch over the tool while breaking or drilling concrete. The units also have a speed control that matches the tool speed to the job. The electronic feedback control circuit provides soft-start and then maintains tool speed under load.

These four new tools are built to last. They have all-metal barrels and gear housings, metal side handles and steel gears and components. The double-insulated construction helps assure safe use in harsh working environments.

The tools are built to operate at least 200 hours before needing planned maintenance. Eight hours before the tool reaches this service interval, the service reminder light glows to alert the operator to complete planned maintenance. If the tool reaches 200 hours without servicing, it will shut down until maintenance is completed.

Servicing the tool is easy. Two service panels have large openings for fast brush and grease changes. Plus, there is no guessing which service kit to use - one kit number works on all four models. Service time is reduced by as much as two-thirds from previous models. Together, Milwaukee's new models lead the field with the best combination of power, performance, comfort and overall ease of use.

The new Rotary/Demolition Hammers are backed by Milwaukee's 5 Year Warranty and Service Plus Program, providing one year of free maintenance when shipped to a Milwaukee Branch Office/Service Center.
