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.
Specifications
Features
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.

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.
Makita's mainstream 40V XGT flagship in the 4-1/2/5-inch class, with a variable 3,000-8,500 RPM brushless motor Makita claims cuts 5/8-inch rebar up to 60% faster than prior cordless. 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. The GAG06 is the paddle-switch sibling; the newer GAG11 swaps the 5/8-11 spindle for X-LOCK.
Milwaukee's braking M18 Fuel grinder, rated equivalent to an 11-amp corded tool with an 8,500 RPM brushless motor. The paddle-switch no-lock configuration is the OSHA-friendly pick; slide-switch and variable-speed siblings (2888) fill out the family.
DeWalt's Power Detect flagship grinder: it senses larger batteries and raises output to 1,350 watts, spinning to a class-leading 9,000 RPM. The Kickback Brake and E-Clutch electronics shut the wheel down on pinch events before the tool wrenches your wrist.
Flex's flagship 24V grinder, part of the brand's 2021 North American relaunch. A sensor-free brushless motor spins 4-1/2 or 5-inch wheels at up to 10,000 RPM - the highest top speed in this roundup - with touch-control speed settings of 3,500/5,000/7,000/10,000 RPM. Anti-kickback sensing stops the motor on bind-up, guard adjustment is one-step tool-free, and the vibration-suppression side handle tames buzz. FX3171A is the no-lock paddle version; FX3181A is the side-switch sibling. THERMA-TECH heat management and 24V packs push it toward corded-class sustained output.
Makita's long-running brushless LXT grinder with Automatic Speed Change: it drops RPM and raises torque under load to keep the wheel moving. The slide switch with lock-on suits continuous grinding; a paddle-switch sibling (XAG09) covers no-lock jobsites.
