  • 8Metabo HPT

  • 9Ryobi One+ HP 18V
    16.07

    15.87, 16.93 seconds, average cut speed 16.3 seconds, by far the slowest of the grinders that completed the 5 lb cut test

  • 10Workpro

    failed the standard 5 lb pressure cut test twice at only 1.46 seconds each attempt; retested at a reduced 2.5 lb of pressure instead, where it finally completed cuts at 30.9 seconds, 69 seconds (restarted after stalling at 52 seconds), and 70 seconds (after 4 restarts)

Torque Test Max Pressure Survived

  • 1Milwaukee M18 Fuel

    easily survived all the way to 20 lb and completed the rebar cut in 14.5 seconds, the fastest of the 5 grinders that met the 20 lb for 10 seconds bar

  • 2Ridgid Octane

    made it through 17.5 lb, then held very high RPM under load at 20 lb but gave up at 21 seconds before finishing the full cut, still counted among the 5 grinders that survived 20 lb of pressure for at least 10 seconds

  • 3Makita (knockoff)

    handled 5, 7.5, and 10 lb with no problem, barely survived 12.5 lb (tied for 2nd best of the brands that failed before 20 lb, alongside the Bosch), then failed at 15 lb, giving up 2.7 seconds into that pass

  • 4DeWalt

    made very easy work of 17.5 lb, then lost blade speed at 20 lb but never gave up, finishing the cut in 65 seconds

  • 5Craftsman

    made very easy work of 17.5 lb, then at 20 lb lost a lot of blade speed but refused to give up, finishing the cut in 85 seconds, one of only 5 grinders to clear the 20 lb for 10 seconds bar

  • 6Makita

    made it all the way to 20 lb, holding RPM as well as the DeWalt, finishing the cut in 35 seconds, one of only 5 grinders to clear the 20 lb for 10 seconds bar

  • 7Bosch

    survived 10 and 12.5 lb (tied for 2nd best of the brands that failed before 20 lb, alongside the knockoff Makita), then failed at 15 lb after about 3 seconds

  • 8Metabo HPT

    made it through 15 lb and appeared to clear 17.5 lb, then failed at 20 lb after only 4 seconds

  • 9Ryobi One+ HP 18V

    bogged down heavily at 7.5 lb, then failed outright at 10 lb in less than 2 seconds

  • 10Workpro

    barely survived 5 lb, then failed at 7.5 lb in under 2 seconds, the worst torque result of any grinder tested

    by far the fastest of any grinder tested

  • 7Bosch
    3.44 seconds
  • 8Metabo HPT

    slower than the knockoff Makita despite the Workpro's lower no-load RPM

How it was tested

  • cutting speed through half inch rebar under 5 lb of pressure, 3 passes per grinder
  • no-load RPM claimed vs measured on a fully charged battery
  • noise level in decibels
  • tool weight
  • torque/stall resistance: cutting a 1/4 inch grinding wheel through rebar under progressively increasing pressure from 5 lb up to 20 lb
  • blade stop / brake speed with a 1/4 inch grinding wheel
  • vibration in m/s2 with a 1/4 inch grinding wheel

So, which brand won the showdown? The Milwaukee did a great job just blasting through that rebar in a very fast time.

From the test video verdict.

Brand head-to-head scoreboards featuring this test

Data notes and caveats

Clean transcript with no significant brand name garbling; all 10 brands (Ridgid, Ryobi, Workpro, Bosch, DeWalt, Craftsman, Makita, Metabo HPT, knockoff Makita, Milwaukee) match the description's Products Tested list exactly. Products array is ordered by the primary declared test, rebar cut speed at 5 lb, best to worst; the video does not provide one single combined score across all five sub-tests, so this order should not be read as an overall composite rank. Narrator gives a clear three tier verdict: Milwaukee as outright winner (fastest cutter, but pricier), Ridgid as the value alternative (nearly as fast, notably cheaper), and the knockoff Makita as the budget pick for anyone already on the Makita battery platform. One price inconsistency: the Milwaukee is introduced at $229 (same price as the genuine Makita) but the closing verdict segment calls it $220, recorded as heard rather than corrected. The Workpro is the only brushed motor grinder and the only one that failed the standard 5 lb cut test outright, forcing a methodology change to a reduced 2.5 lb pressure for its cut timing, so its cut times are not directly comparable to the other 9 brands' 5 lb results. The Metabo HPT was tested with a smaller 3 amp hour battery instead of the 4 amp hour battery used on every other brand, a stated methodology caveat.
