Makita Reconditioned GA7040S-R 7-Inch 15 Amp Soft Start Angle Grinder

The Makita Reconditioned GA7040S-R 7-Inch 15 Amp Soft Start Angle Grinder is an industrial corded power tool engineered to deliver 8,500 RPM for heavy-duty metal grinding, masonry cutting, and weld smoothing. Powered by a 15.0 Amp motor running on 120V power, this 14.2-pound grinder features soft-start electronics and a 180-degree rotatable rear trigger handle. Built with protective labyrinth motor sealing and a tool-less wheel guard, this 7-inch grinder solves severe dust contamination and gear-wear challenges across structural steel fabrication and masonry jobsites.

Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.

Best Used For:

  • Heavy Weld Bead Smoothing & Bevelling: Rapidly grinding down heavy steel weld seams and chamfering thick plate edges prior to structural joining.
  • Concrete & Masonry Tuckpointing: Slicing expansion joints and removing excess mortar in concrete slabs and brickwork using 7-inch diamond blades.
  • Industrial Rust & Scale Removal: Stripping heavy corrosion, mill scale, and paint from heavy machinery frames and iron pipes.

Key Performance & Safety Features

  • 15.0 Amp High-Torque Motor: Maintains a consistent 8,500 RPM under severe grinding loads for fast, efficient stock removal.
  • Soft Start Technology: Suppresses initial torque kickback upon startup to ensure smooth power delivery and extend gear system life.
  • Labyrinth Sealing Construction: Seals motor windings, bearings, and gears against airborne concrete dust and metal filings for extended service life.
  • Rotatable Ergonomic Handle: Rear trigger handle rotates 180 degrees with positive stops to optimize operator leverage during vertical or overhead cutting.
  • Spiral Bevel Gear System: Precision-machined steel gears deliver smoother rotation, reduced operational noise, and efficient energy transmission.
  • Tool-Less Wheel Guard: Allows fast, tool-free guard rotation to keep sparks and debris directed away from the operator.
