SKU : WOR-TOO-020
The DEWALT DWASHRIR Impact Ready Shears Attachment turns your 18V–20V impact driver or drill into a power shear for clean, fast cuts in sheet metal and other tough materials. It cuts through 18-gauge steel, aluminum, duct, corrugated metal, vinyl siding, wire, plastic, cardboard, and rubber.
The 360° swivel head lets you keep the tool stable while moving the cutting head around corners and through curved lines. It connects with a standard 1/4-inch hex shank, so it works with most impact drivers and drills, regardless of brand.
Use it for heating and air conditioning ductwork, metal roofing, flashing, siding, wire shelving, and even shingles. The shear leaves a clean edge and doesn't create sparks like a grinder.
Insert the 1/4-inch hex shank into your tool's chuck, tighten, and you're ready. No special adapter needed. The attachment is tool-only; impact driver/drill not included.

This shear attachment turns your driver into a compact metal cutting tool for ductwork, roofing, siding, and more.
The 360° head lets you cut from any angle without repositioning the drill, making overhead cuts and tight corners easier.
Because it uses a standard 1/4-in hex shank, it works with the tools you already own—no proprietary adapter needed.
Yes, the 1/4-inch hex shank is standard and fits most 18V–20V impact drivers and drills from any major brand.
It cuts up to 18-gauge steel, about 0.048 inches thick, and equivalent non-ferrous materials.
The 360° swivel head helps you guide the cut along curves and corners, but very tight radii may require relief cuts.
Shears produce no sparks, create a cleaner edge, and generate less noise and dust than cutoff wheels.










Fantastic shear.
I used it to cut duct work in a tight space. The 360-degree head let me navigate corners without repositioning. It cuts clean through 18-gauge steel. The installation on my impact driver was simple. It feels solid and has held up well. A great addition to my toolkit.
I'm on the older side and this attachment makes cutting metal easy. It cuts well, but it's a bit heavy on the drill.
The 360 head is awesome. I can cut in any direction without moving the tool.
It saved me hours on a metal roofing project. Highly recommend.
It works but you need a powerful impact. The instructions were not great.
I love this attachment. It cuts metal cleanly.
It's well made and cuts smoothly.
I'm not a professional but it worked great for my project.
Solid attachment. Cuts sheet metal like paper.
