The S5AGR-Li 5" Cordless Angle Grinder is a powerful, versatile addition to the Evolution lineup, designed for cutting, grinding, and finishing across a wide range of metalworking applications.
Powered by a high-performance 20V brushless motor delivering 8700 RPM, it provides consistent, stall-free performance for demanding tasks. While Evolution’s cold cutting technology leads in precision, low-spark cutting, angle grinders remain essential for abrasive applications, and the S5AGR-Li is built to complement that capability.
Designed with usability in mind, it features tool-free adjustments, an ergonomic grip, and a compact form factor for improved control in tight or awkward spaces. As part of the Evolution cordless platform, it offers great value and shared battery compatibility, making it a practical choice for both trade professionals and serious DIY users.
