Makita GA5052 4-1/2-Inch / 5-Inch 11.0 Amp Corded Paddle Switch Angle Grinder with AC/DC Power Switch

The Makita GA5052 4-1/2-Inch / 5-Inch Paddle Switch Angle Grinder is an industrial electric surface preparation tool engineered for high-volume weld grinding, structural steel beveling, and masonry scoring. Driven by an 11.0-amp motor operating at 11,000 RPM, this 6.2-pound corded grinder features an AC/DC selector switch that permits operation from standard wall outlets or direct-current jobsite generators. Outfitted with a two-stage no-lock-on paddle switch, an integrated lanyard tethering loop, a tool-less 5-inch wheel guard, and spiral bevel gears, this narrow barrel-grip tool incorporates labyrinth housing seals and zig-zag epoxy coil coatings to shield drive bearings from conductive grinding dust.

Best Used For:

  • Generator-Powered Remote Steel Fabrication: Running metal prep tools off jobsite DC welding generators or AC outlets using the built-in AC/DC selector switch.
  • Elevated Scaffolding Weld Grinding: Securing safety lanyards directly to the integrated steel tether loop for fall-protection compliance on aerial lifts.
  • Heavy Masonry & Steel Joint Scoring: Cutting concrete expansion joints and milling down thick weld seams with 5-inch wheels at 11,000 RPM.

Key Performance & Safety Features

  • 11.0 Amp Industrial Motor Output: High-output motor maintains 11,000 RPM under heavy downward feeding pressure to prevent wheel stalls during continuous grinding.
  • Dual AC/DC Power Selector Switch: Internal rectifier circuitry allows the operator to power the tool via standard AC grid power or DC generators.
  • Integrated Lanyard Tether Loop: Built-in structural tether anchor point connects directly to safety lanyards to satisfy elevated jobsite safety codes.
  • Two-Stage No-Lock-On Paddle Switch: Large paddle switch features a safety lock-off lever to prevent accidental startup across multiple hand grip positions.
  • Tool-Less Quick Guard Adjustment: Spring-loaded guard latch enables fast rotation adjustments without requiring additional hand tools.
  • Labyrinth Housing Dust Seals: Complex baffle channels isolate motor armatures and drive bearings from metal shavings and concrete dust.
