Shed the Cord and Slice Through 16-Gauge Sheet Metal with Brushless Precision

Experience unrestricted commercial-grade mobility and high-performance metal fabrication with the Bosch GNA18V-16EN 18V Brushless Cordless 16-Gauge Sheet Metal Nibbler. Engineered to replace cumbersome corded units while matching their output, this robust industrial tool is powered by an advanced brushless motor that yields the equivalent of a 700W corded tool. It allows mechanical contractors, HVAC fabricators, and roofing installers to cut seamlessly through thick 16-gauge structural steel, corrugated panels, and multi-walled ventilation ducts. Featuring a specialized tool-free rotating die holder, users can instantly change cutting directions to navigate tight straightaways, compound right-angle corners, or complex artistic curves without distorting or bending the workpiece edges.

Ergonomically balanced to eliminate long-term fatigue during full-shift layouts, the nibbler features an ultra-slim barrel profile covered in a vibration-dampening soft-grip skin. To protect your investment and secure a safe jobsite environment, Bosch has equipped this cordless unit with electronic soft start to minimize initial kickback torque, restart protection to stop accidental activation during battery changes, and automated overload motor protection to prevent thermal damage during high-load aggregate stress. Delivering sharp, burr-free cuts that require zero secondary grinding or finishing, this portable nibbler drops cleanly into your established 18V tool fleet to maximize productivity.

Key Features

  • 700W Corded-Equivalent Power: Industrial brushless motor setup delivers fast, punchy strokes to glide through 16-gauge metals with total cordless freedom.
  • 360-Degree Rotating Die Holder: Offers quick, tool-free directional indexing (straight, right, or left) for extreme maneuverability around roof ridges and HVAC duct configurations.
  • Clean Burr-Free Punching: Slices metal cleanly without creating sharp shards, keeping waste minimal and preventing structural panel distortion.
  • Smart Electronic Safety Array: Outfitted with soft start to ensure smooth initial panel contact and restart protection to prevent unwanted motor ignition.
  • Active Overload Performance Protection: Internal monitors watch temperature thresholds to shut down power during extreme loads, extending the life of the tool components.
  • Ergonomic Lightweight Layout: Weighing only 4.25 pounds, the balanced chassis minimizes strain during continuous downward overhead or vertical cuts.

PRO-TIP: When processing high-volume metal runs or cutting corrugated steel roofing panels, apply a few drops of light machine oil or cutting fluid directly along your planned cut line. Because a nibbler works via a rapid-punching action, proper lubrication reduces friction on the punch and die, resulting in noticeably smoother paths, minimized operator push-force, and up to double the service life on your consumable cutting parts!
