Overview

The BullTech BT-5015 is a practical 2-in-1 cordless kit that combines a 125mm angle grinder and a cordless drill/driver in one set. Powered by 48V Li-ion batteries (2× 5.0Ah), it’s built for workshop and jobsite use where mobility matters. The brushless motor improves efficiency, delivers more power with less energy use, and reduces maintenance because there are no brushes to wear out.
The grinder features a comfortable central switch layout, a rubberised body for better grip and impact protection, and additional air intakes for cooling during continuous work. A 4-level speed control and battery charge indicator make it easy to match performance to the task.
