Product description

The pneumatic hammer mechanism of the Worx H3 WX394 cordless rotary hammer delivers an impressive 1.5 Joules of impact energy for fast drilling in reinforced concrete. The H3 is surprisingly lightweight and compact for its power, making it ideal for overhead and other critical applications where conventional corded rotary hammers would be awkward and heavy to operate. Unlike similar compact rotary hammers that force you to buy specific drill bits, the Worx H3 accepts all SDS Plus bits. As an additional benefit, its supplied plug-in chuck converts the rotary hammer into a drill that uses round shaft bits, while the one-touch 6.35 mm hex chuck transforms it into a powerful driver. ​This tool is part of the expanding Worx PowerShare, one of the most versatile cordless platforms that covers power tools, lawn and garden tools and everyday life products. PowerShare's "One Battery, Expandable Power" means the same 20V battery can be used in multiple configuration to power up 40V and 80V products.
