High Velocity Wireless Auto Start Powertrain with Snap-On Wheel Exchange for Heavy Industrial Production

The Makita GAG11Z 40V Max XGT Brushless 5-Inch Angle Grinder is a battery-powered cutting and surface preparation tool engineered to deliver up to 60% faster cutting speeds across demanding masonry and metal fabrications. Driven by an advanced industrial brushless motor powered by the high-voltage XGT system, this cordless power tool maintains variable operating speeds from 3,000 to 8,500 RPM under load. The architecture integrates an automated snap-on X-LOCK spindle interface for tool-free accessory changes, Active Feedback-sensing Technology (AFT) for instant bind-up mitigation, a rapid 2-second electric safety brake, and Bluetooth AWS capability for wireless dust extractor communication.

**Battery and charger sold separately.

Best Used For:

  • Thick Metal Cutting: Slicing rapidly through heavy-gauge galvanized conduit tracks, structural unistrut channels, and raw steel reinforcing rebar plates.
  • Production Weld Dressing: Stripping coarse structural weld lines, beveling plate steel edges, and removing hard carbon scale buildup uniformly.
  • Masonry Expansion Jointing: Scoring straight, crisp relief channels and trimming composite paving blocks, concrete walls, or tile surfaces with dust extraction integration.

Key Performance & Safety Features

  • X-LOCK Mount Architecture: Snap-on accessory interface locks grinding wheels instantly without nuts and detaches rapidly via a physical lift-lever mechanism.
  • XGT 40V Commercial Power: Advanced high-voltage electronic platform yields corded-equivalent torque output for high-load industrial cutting cycles.
  • AWS Vacuum Synchronization: Auto-Start Wireless System provides automated Bluetooth communication to trigger matched dust collectors simultaneously during grinding.
  • AFT Back-Torque Protection: Intelligent electronic feedback loop triggers immediate motor shutdown if the cutting wheel jams or experiences sudden speed loss.
  • Two Second Active Brake: Integrated electrical braking mechanism decelerates rotating cut-off wheels to a complete stop within 2 seconds for operator protection.

What's Included

  • (1) 40V Max XGT® Brushless 5" X-LOCK Angle Grinder (GAG11Z)
  • (1) X-LOCK 5" x 1/4" x 7/8" Metal & Stainless Grinding Wheel, 36 Grit (E-00468)
