Bosch GOP12V-28N 12V Max EC Brushless Starlock Oscillating Multi-Tool Bare Tool

The Bosch GOP12V-28N 12V Max Cordless Oscillating Multi-Tool operates as a compact variable-speed power cutter and sander engineered to execute flush cuts, plunge cuts, and grout removal in restricted spaces. Powered by a 12V Max brushless motor, this 1-3/4 lb. bare tool delivers 5,000 to 20,000 oscillations per minute across an aggressive 2.8-degree oscillating arc. Outfitted with the Starlock 3-D tool-accessory connection interface, magnetic-assisted accessory positioning, protective no-mar body ribs, and an 11-1/5 in. long aluminum gear housing, this tool enables finish carpenters, tile setters, and remodeling contractors to perform flush-cutting on doorjambs, wood trim, drywall, and copper pipes.

**Battery and charger sold separately.

Best Used For:

  • Doorjamb & Casing Flush Cutting: Trimming wood doorjambs and baseboards flush to subfloors for tile, laminate, or hardwood floor installations.
  • Cabinet & Drywall Plunge Cutting: Executing plunge cuts into electrical junction box openings, cabinet backs, and subflooring without damaging surrounding trim.
  • Grout Removal & Detail Sanding: Scraping damaged tile grout and sanding intricate wood profiles in tight interior corners using Starlock attachments.

Key Performance & Safety Features

  • Starlock 3-D Accessory Interface: Cupped 3-D connection delivers rigid mechanical contact to prevent slip and maximize torque transfer to the blade tip.
  • Commercial EC Brushless Motor: High-efficiency brushless motor delivers cool operation, extended battery runtime, and maintenance-free service life.
  • Aggressive 2.8-Degree Oscillating Arc: Engineered oscillating angle provides fast material removal rates during wood cutting and tile grout scraping.
  • Precision Variable-Speed Dial: Thumb dial adjusts speed output from 5,000 OPM up to 20,000 OPM to match delicate detail work or heavy cutting.
  • Magnetic-Assisted Blade Mounting: Internal magnet holds Starlock accessories steady on the spindle mount for rapid, hassle-free blade position adjustments.
  • No-Mar Body Guard Ribs: Integrated plastic protective ribs elevate the aluminum gear housing to prevent scratching adjacent finished workpieces.

Pro-Tip: When undercut-cutting doorjambs with the Bosch GOP12V-28N, lay a scrap piece of your new flooring directly on the subfloor as a height guide and rest the plunge blade flat against it. Setting speed to 15,000 OPM provides smooth control that prevents wood scorch while producing a accurate, flush clearance gap for new flooring installations.
