Sheet metal cutting attachment for HVAC installers, roofing contractors and metal fabrication professionals
The DeWalt DT70620-QZ EXTREME® 18GA Impact Shear Attachment converts a standard impact driver or drill into a powered sheet metal cutting solution for HVAC ducting, roofing panels, galvanised steel and light fabrication work. Designed for cutting up to 18 gauge material equivalent to approximately 1.3 mm steel sheet, the mechanism transfers rotational output into controlled reciprocating shear action suitable for straight cuts and curved profiles. The impact-resistant transmission housing is engineered for repetitive cutting applications on site without requiring a dedicated standalone shear tool.
The 360° rotating head improves manoeuvrability when cutting curved sections, ventilation ducting and formed metal profiles in confined installation environments. Compared with manual aviation snips, the powered cutting action reduces operator fatigue and improves consistency across long cutting runs. The attachment format allows installers already using cordless impact drivers to expand cutting capability without adding another motor platform or battery system to the tool inventory.
