Summary

Milwaukee's M18 FUEL 115mm Angle Grinder is a robust cordless option with strong build quality and a reliable brake, but it comes at a premium price.

Findings

In use, the tool feels built for the long haul. The cast aluminium gear case and rubber over-mould provide a solid, confident grip and peace of mind when grinding in tight spaces or overhead. The balance is noticeably good for a cordless 115mm grinder, helping control during prolonged sessions. The fast brake is a standout feature, stopping the disc quickly after release to reduce downtime and kickback risk on site. Disc changes are straightforward thanks to the spindle lock and tool-free guard adjustment, which makes swapping wheels with gloves on a breeze in a busy workshop or on a windy build site. The POWERSTATE brushless motor delivers consistent torque and maintains speed under load, giving predictable material removal without aggressive rpm fluctuations. Electronic safety features, including clutch and brake, contribute to operator comfort and disc protection during tough jobs. Run time from the M18 battery platform is reliable enough for a solid day's work, and the ecosystem compatibility means you can share batteries across tools on site. On the downside, the upfront cost sits at the premium end, and the total package--with battery and charger if required--adds up. The unit is noticeably heavier with a full-size battery compared with some corded 115mm grinders, which can affect use when working overhead or in confined spaces. Battery performance can dip in very cold conditions or under sustained heavy use, and accessory costs within the Milwaukee ecosystem are higher than generic equivalents. Overall, for tradespeople invested in the M18 system, it offers strong value through durability and on-site productivity; for those weighing budget against cordless convenience, the premium price is the main consideration.
