Makita GA9060 9-Inch 15.0 Amp Corded Heavy-Duty Angle Grinder with Lock-On Switch

The Makita GA9060 9-Inch Angle Grinder is an industrial electric metalworking and masonry grinding tool engineered for high-volume weld removal, steel plate beveling, and concrete joint scoring. Driven by a 15.0-amp motor operating at 6,600 RPM, this 12.1-pound corded grinder features an aluminum gear housing that rotates every 90 degrees to optimize trigger positioning. Outfitted with a 9-inch wheel guard, labyrinth dust seals, zig-zag protective epoxy coatings on the armature coils, spiral bevel gears, and a 3-position side handle, this 17-3/4 inch machine utilizes auto-cutoff carbon brushes to shield the motor during heavy shipyard and structural fabrication tasks.

Best Used For:

  • Heavy Structural Steel Weld Removal: Milling down thick structural weld seams and beveling heavy plate edges using 9-inch grinding wheels at 6,600 RPM.
  • Deep Concrete & Brick Masonry Cutting: Scoring control joints and cutting thick brick, paver stones, and foundation blocks with 9-inch diamond blades.
  • Industrial Rust & Scale Stripping: Removing heavy mill scale, ship hull corrosion, and rust from steel plate stock using wire cup brushes.

Key Performance & Safety Features

  • 15.0 Amp High-Output Industrial Motor: High-torque motor delivers 6,600 RPM for continuous heavy grinding without wheel bogging under downward pressure.
  • Labyrinth Housing Dust Seals: Complex internal channels seal drive bearings and motor armatures against abrasive metal shavings and silica dust.
  • Zig-Zag Armature Coil Protection: Protective epoxy coatings baked onto armature coils prevent dust particle impact from damaging internal wiring.
  • Spiral Bevel Gear Transmission: Heavy-duty bevel gear train ensures smooth rotational power transfer and maximizes gear life under load.
  • 3-Position Adjustable Side Handle: Mounting ports on top, left, and right sides permit custom hand placement for right- or left-handed leverage.
  • Auto-Cutoff Carbon Brushes: Spring-loaded brushes automatically disengage commutator contact when worn to protect the armature from damage.
