Flex Mini Grinder and Cut-Off Tool

It looks like Flex has a new 24V cordless mini grinder and cut-off tool, model FXA3111A.

The new Flex cut-off tool and grinder is designed to “deliver big power in a compact size.”

It’s mainly for “cutting and surfacing applications.”

The tool has a 76mm (3″) wheel size.

  • 3″ wheel size (9.5mm arbor)
  • 4 speed settings
    • 5K, 10K, 15K, 20K RPM
  • Anti-kickback brake
  • Rotating tool head
  • Adjustable speed
  • One-step guard adjustment
  • Dual LED worklight
  • Weighs 0.85 kg (~1.87 lbs)

The rotating head seems interesting, allowing users to cut or grind to the right, to the left, or from above.

It shops with a sampling of accessories, clip-on cutting guard, dust extraction hose connector, belt clip, and hex wrench.

At this time Flex has only announced the new cut-off tool and grinder overseas. USA details are not yet available.
