The KD-400 18 Gauge Metal Electric Shear is designed to cut cold-rolled mild steel up to 18 gauge and most grades of stainless steel up to 20 gauge at a rapid rate of 300 inches per minute. The controlled waste strip prevents warping or burring of your finished piece. The variable speed 2500 RPM electric motor paired with our A-2 steel blades helps you maneuver tighter curves for fast, clean performance on the job.
