Bosch PROFACTOR 18V Spitfire GWS18V-13CN Angle Grinder

Bosch's PROFACTOR-tier 'Spitfire' flagship grinder, pairing a BITURBO brushless motor with CORE18V High Power batteries to claim 13-amp corded-equivalent output. Runs 5- or 6-inch wheels at 9,000 RPM on a standard 5/8-11 spindle, with an electric brake, KickBack Control that shuts the tool off in a bind, restart protection, and a Vibration Control two-position side handle. Connected-ready for the Bosch PRO360 app (module sold separately); the GWS18V-13PN is the paddle-switch sibling and the GWX18V-13CN swaps to X-LOCK.

Pros

  • BITURBO motor genuinely reaches corded 13-amp-class output when fed a CORE18V 8Ah+ High Power pack - among the strongest 18V grinders sold.
  • Handles 6-inch wheels, giving more depth of cut than the 4-1/2/5-inch rivals in this class.
  • KickBack Control shuts the motor off in bind-up situations - a real safety layer on top of the electric brake.
  • Electric brake plus restart protection and electronic clutch round out a complete safety-electronics package.
  • At 5.1 lbs bare it is light for the power class - lighter than Makita's 40V XGT grinder by a wide margin.
  • Standard 5/8-11 spindle means no X-LOCK accessory lock-in, and the quick-change lock nut is tool-free.
  • Connected-ready: PRO360 module adds tracking and custom settings for fleet users.
  • Five-year limited warranty on PROFACTOR tools is the longest in this roundup.

Cons

  • Needs CORE18V High Power (8Ah/12Ah PROFACTOR) batteries to hit rated output - regular 4Ah packs throttle it noticeably.
  • Slide switch with lock-on is prohibited on some jobsites; you must buy the GWS18V-13PN paddle version instead.
  • At ~$259 bare it is priced above Milwaukee/DeWalt 18V flagships that include kit options more cheaply.
  • Connectivity module is sold separately, so the 'connected' feature costs extra.
  • Bosch's cordless share in North America is smaller, so batteries and promos are less ubiquitous than red/yellow platforms.
  • No variable-speed dial - single 9,000 RPM speed limits flap-disc finesse work.
  • Major-retailer review volume is thin for this SKU, so long-term owner signal is limited.

Angle Grinder

The October 2024 successor to Metabo HPT's original G3612DA, with a 1500W-max brushless motor the company rates at 18% more power than the outgoing model. A 6-position dial spans 3,200-10,000 RPM plus an auto mode, and the safety package includes an electric quick brake, anti-kickback protection, soft start, and zero-voltage restart protection. Dust- and water-resistant switch, tool-less wheel guard, and dual LED work lights round it out. Being MultiVolt, it runs on 36V packs or Metabo HPT's AC adapter - the only grinder in this class that can go corded. G3612DVFQ6 is the paddle-switch twin; G3615DVFQ6 is the 6-inch big brother.

Electric brake stops the wheel in under 2 seconds, AFT kills the motor on bind-up, and it's AWS-capable for auto-starting Makita dust extractors.
