⚠️ Known Issues
- This adapter is compatible with all battery capacities (Ah). However, weak or low-capacity batteries below ~3Ah may experience reduced performance or unstable operation.
-
Due to the built-in delayed output protection, some Kobalt 24V angle grinders may require a short restart sequence.
Turn the tool switch on briefly, wait approximately 3 seconds, then turn the switch on again for normal operation.
Most drill-style tools do not require this additional step.
SKU PTA-MIL18-KOB24
Description
The Milwaukee 18V M18 to Kobalt 24V battery adapter allows you to operate Kobalt 24V cordless tools with the Milwaukee batteries you already have in your lineup. It is ideal for professionals looking to simplify their power setup, reduce the number of chargers on site, and keep projects moving without interruption.
On the battery side, the adapter uses a rugged injection-molded ABS interface, while the tool side is produced from high-precision 3D-printed ABS. Inside, smart battery protection electronics (BMS) work together with a DC-DC voltage boost system to deliver the correct power level for your equipment. Heavy-duty copper terminals provide reliable, repeatable current transfer in both workshop and field conditions.

Important Note – Kobalt 24V Angle Grinders
Due to the adapter’s internal output delay protection, certain grinders may require a short restart routine:
- Switch the tool on briefly
- Wait roughly 3 seconds
- Switch it on again
Once completed, the tool should run normally. Drill-type tools usually start immediately without this process.
