Milwaukee M18 CAG125X-502X is a cordless angle grinder built around the brand's M18 18 V lithium-ion platform. Its 125 mm disc size and 8,500 rpm no-load speed place it in the compact grinder class for metal grinding and cutting work.

Core Specifications

The grinder accepts 125 mm discs through an M14 spindle thread. Milwaukee's published European catalog data lists a maximum cutting depth of 33 mm and a weight of 2.5 kg with a battery attached.

The set uses two 5.0 Ah REDLITHIUM-ION battery packs. It also includes a charger and an HD Box case, while the tool uses a slide switch and a FIXTEC system for accessory changes.

Kit And Compatibility

The M18 designation identifies compatibility with Milwaukee's 18 V M18 battery platform. The included batteries make this a complete kit rather than a bare tool, but the European model number 4933448866 should be matched carefully against the regional product listing.

Its M14 spindle and 125 mm disc format follow a widely used angle-grinder accessory standard. The listed 33 mm cutting depth gives the tool a defined limit for cutting applications, while the 8,500 rpm speed is specified as no-load speed rather than a loaded cutting speed.

Position In The Category

The M18 CAG125X-502X combines a cordless 18 V platform, two 5.0 Ah batteries, a charger, and a case. Compared with a bare-tool grinder, the kit provides the power system and charging hardware in the package, but the added batteries also make the set heavier to carry.
