Why consider this model?

  • A buyer comparing earlier full-size M18 saws who values documented ONE-KEY speed/output customization and tool tracking and already owns a compatible battery and charger.

Tradeoffs to weigh

  • The exact package is tool only, its manual specifies a 1-1/8 in stroke and 3-1/2 in minimum blade length, and the official sources do not state a bare-tool weight. Milwaukee's Gen 2 announcement names 2822 as replacing 2721, so this is an earlier reference rather than the newest One-Key generation.
