Pros & cons

Bosch PROFACTOR 18V Spitfire GWS18V-13CN Angle Grinder

  • 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.
  • 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.

Metabo HPT MultiVolt G3612DVE Angle Grinder

  • 1500W maximum output is genuinely corded-class - Pro Tool Reviews positions it as a true alternative to Metabo HPT's own corded grinders.
  • MultiVolt hybrid design is unique in this roundup: pop in a 36V pack in the field or run the optional AC adapter for unlimited bench runtime.
  • Six-setting speed dial (3,200-10,000 RPM) plus auto mode covers cutting, grinding, flap-disc blending, and polishing.
  • Complete safety electronics: quick brake, anti-kickback shutoff, soft start, and zero-voltage restart protection.
  • 5.1 lbs bare is light for a 36V tool, and the slim grip helps smaller hands.
  • Tool-less wheel guard and spindle lock make wheel changes quick.
  • Dual LED lights on the gear housing - a rarity on grinders - genuinely help in dark corners and inside weldments.
  • Dust- and water-resistant switch suits dirty grinding environments.
  • $249 bare is the priciest 4-1/2-inch tool in this roundup, and there is no kit option to soften the battery buy-in.
  • Only a 1-year warranty - far behind Bosch's 5 years and Ridgid's lifetime service agreement.
  • 36V MultiVolt packs are big and heavy; with a battery the tool climbs past 7 lbs, eroding the light bare weight.
  • The AC adapter that enables corded use is a separate ~$100+ purchase.
  • Slide switch with lock-on is disallowed on some jobsites - you must buy the G3612DVFQ6 paddle version instead.
  • Metabo HPT's dealer network and battery promos are thinner than DeWalt/Milwaukee in North America.
  • Launched late 2024, so retailer review volume is still too thin to establish long-term reliability signal.
