If you’re chopping sheet metal without trailing a cord, the DeWalt DCS491NT 1.3mm Cordless Metal Shear Bare is a solid choice — this XR‑series 18V shear lets you work where a cable simply won’t reach. It’ll chew through thin gauge steel and similar metals up to about 1.3 mm thick without much fuss, so you’re not stuck pulling out tin snips for every job.

Since it’s sold as a bare tool, there’s no battery or charger in the box — ideal if you already run DeWalt 18V gear and just need another head in your tool bag. The bottom line is you get trade‑ready metal cutting where you need it without paying for extras you don’t need.

Key Features:

• 1.3 mm Cutting Capacity - Handles sheet metal and light gauge steel cleanly and consistently.
• Variable Speed Trigger - Gives you fine control during starts and tight cuts.
• D‑Handle Design - Comfortable grip and balance keep you working longer with less fatigue.
• 360° Swivel Head - Lets you get into tight corners and awkward angles without strain.
• Cordless Convenience - Cut anywhere without dragging a lead around the jobsite.

Applications

Sheet metal work, HVAC fitting, and profile cutting are right up this shear’s alley — the cutting capacity of 1.3 mm means it’ll go through mild steel and similar metals that you’d usually wrestle with hand shears, fast and far more comfortably. It’s a real time‑saver in ductwork and fabrication, especially on overhead or tight spots where a plug simply doesn’t exist.

Why Choose This Model

Here’s the thing — if you already run 18V DeWalt batteries, this tool just slots right into your kit. The bare format keeps the cost down if you’re topping up your fleet, and that variable speed trigger gives you real feel on start‑up and through cuts. In practice, that matters a lot on a job site where sloppy starts and floppy handles wear you down fast.

Technical Specifications Explained

• Voltage – 18V - Works with your existing XR battery packs without needing an adaptor.
• No Load Stroke Rate – 0–2450 spm - Fast blade action for brisk, consistent cutting through sheet material.
• Cutting Capacity – 1.3 mm - Good for thin steel, aluminum, and similar non‑ferrous sheets without leaving ragged edges.
• Weight – ~1.8 kg - Light enough to handle all day without tiring your arms out.
• Swivel Head - Adjusts blade orientation on the fly so you can follow contours and profiles more easily.

Who Should Buy This

If you’re a pro metal worker, HVAC installer, or fabricator with an existing DeWalt 18V ecosystem and you cut sheet metal often, the DeWalt DCS491NT 1.3mm Cordless Metal Shear is something you’ll use — plain and simple. It’s not a toy; it’s built for real jobsite conditions and repeated use.

But don’t bother if you’re an occasional DIYer — unless you have a stack of DeWalt 18V batteries already, grabbing the kit version with a battery makes more sense. This bare tool shines when it’s part of a broader cordless lineup you already count on.
