Brushless 8000 RPM Rat-Tail Grinding Matrix for Heavy-Duty Pipeline Fabrication

The DEWALT 7 Inch Brushless Rat-Tail Small Angle Grinder delivers a heavy-duty corded abrasive processing system engineered to serve as a primary steel cutting and weld-smoothing station for high-stress industrial pipeline fabrication. Powered by a high-efficiency brushless motor maintaining a constant 8000 RPM, this electric hand tool resolves maintenance-related downtime by eliminating mechanical carbon brush replacements entirely. The specialized configuration integrates an extended rat-tail trigger housing with a 2-stage safety switch and an internal kickback brake matrix, instantly killing tool rotation when severe blade pinching, binding, or unexpected jobsite electrical loss events are encountered.

Best Used For:

  • Pipeline Root Pass Cleaning: Grinding out and prep-cleaning narrow pipe bevel joints using the precise soft gear case grip surface.
  • Industrial Weld Smoothing: Removing massive structural steel bead seams flush across heavy construction beams and plates.
  • Heavy-Duty Wire Brushing: Stripping thick rust scales, slag layers, and surface coatings off large industrial metal substrates.

Key Performance & Safety Features

  • Brushless Motor System: Advanced brushless engineering maximizes electrical conversion and completely eliminates maintenance-heavy brush changes.
  • Rapid Dynamic Braking: Internal mechanical stopping system halts wheel inertia in 4 seconds or less on average during operational shut-down sequences.
  • Electronic Kickback Brake: Automatically activates with full force when a pinch, stall, or bind-up is sensed to quickly shut the motor off.
  • Power-Loss Reset Safety: No-volt release function prevents automatic restart after power outages, requiring switch cycling to re-engage.
  • Integrated Lanyard Anchorage: Built-in structural tether point allows attachment of drop-prevention lanyards to safeguard high-elevation job sites.
  • Soft Gear Case Pipeline Cover: Ergonomic gripping sleeve provides precise directional handling exclusively during specialized edge wire brushing.

What's Included

  • 1 DEWALT 7 Inch Corded Electric Brushless Grinder
  • 1 Ergonomic Side Handle
  • 1 Hex Adjustment Key Wrench
  • 1 Inner Flange Nut
