Dust Extraction Attachment for Cordless Rotary Hammers

The 402976M Dust Extraction Attachment is a high-performance dust collection system designed specifically for compatible cordless rotary hammers, helping professionals maintain a cleaner, safer, and more productive work environment. Featuring an integrated HEPA filtration system, this self-contained attachment captures 99.97% of airborne particles measuring 0.3 microns and larger, making it compliant with OSHA silica dust exposure regulations. Ideal for concrete drilling, anchor installation, electrical work, plumbing, HVAC, and renovation projects, it significantly reduces airborne dust while improving jobsite visibility and cleanliness.

Designed for seamless integration, the 402976M mounts directly to the rotary hammer and draws power from the tool's battery, eliminating the need for separate power sources or external vacuum systems. The precision guide hole aligns accurately with the drill bit, ensuring efficient dust collection without interfering with drilling performance. An automatic shut-off function with a three-second delay continues operating after the trigger is released, allowing the unit to capture any remaining airborne dust before powering down.

Built for everyday professional use, the 402976M combines efficient dust extraction with a compact, lightweight design that minimizes user fatigue while maximizing mobility on the jobsite. Whether you're drilling overhead, installing anchors, or working indoors where dust control is essential, this attachment provides reliable performance while helping maintain compliance with workplace safety standards.
