How do I maximise battery life with Milwaukee cordless angle grinders?

To optimise battery performance and longevity, Milwaukee recommends several practices: use sharp, appropriate discs for the material being worked, as dull or incorrect discs increase motor load and drain batteries more rapidly; avoid forcing the tool, allowing the disc to work at its designed speed; store batteries in moderate temperature environments, as extreme cold or heat affects performance and lifespan; charge batteries before they're completely depleted when possible, as REDLITHIUM batteries don't suffer memory effects; and use the appropriate battery capacity for your application, as HIGH OUTPUT batteries maintain voltage better under sustained heavy loads. Regular cleaning of tool ventilation slots also ensures efficient motor cooling, reducing strain on both motor and battery systems.

Are Milwaukee cordless angle grinders suitable for cutting masonry and concrete?

Yes, Milwaukee cordless angle grinders are entirely suitable for masonry and concrete cutting applications when fitted with appropriate diamond cutting discs rated for these materials. The M18 FUEL models deliver sufficient power and sustained runtime for professional masonry work, though cutting harder materials naturally consumes more battery capacity than metalwork. For extensive masonry cutting, using higher-capacity M18 batteries (6.0Ah or larger) is recommended to maximise productivity between charges. Always ensure diamond discs are specifically rated for the material being cut and that the maximum disc speed rating exceeds the grinder's no-load speed. Wet cutting attachments can be used with Milwaukee grinders when cutting masonry to reduce dust generation, though appropriate waterproofing precautions should be observed with cordless tools.
