The DEWALT DW890 18 Gauge Swivel Head Metal Shear is a powerful, versatile cutter for sheet metal users who need a clean line without constant repositioning. Its 5-amp, all ball-bearing motor drives a swivel head that rotates 360 degrees, letting you cut in any direction while keeping a clear line of sight on the work piece.
DEWALT DW890 18 Gauge Metal Shear: Accuracy and Maneuverability
The DW890 cuts a 7/32-inch strip that curls away from the cutting area, so you can see exactly where you’re going. A variable speed dial lets you adjust stroke rate from 100 to 350 SPM, matching the tool to the material thickness and hardness. It cuts radius curves of 5-1/2 inches and larger, making it useful for HVAC, auto body, and fabrication work.
DW890 Replacement Blades and Stainless Steel Cutting
When the cutting edges dull, DW890 replacement blades are straightforward to install — remove the screws on the cutter head, swap in new blades, and re-torque. This shear can handle 18-gauge stainless steel, though you’ll want to use a slower speed and lighter pressure to avoid heat buildup and premature blade wear. For tougher alloys, use cutting fluid and let the tool do the work.
What to Consider Before Buying
This is a dedicated metal shear, not a nibbler. It excels at straight and gently curved cuts in sheet metal, but it’s not designed for tight corners or piercing. If you regularly cut ductwork, siding, or other 18-gauge materials, the DW890 is a solid workhorse.
