What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Ridgid R86040B 18V X4 4-1/2 in. Cordless Angle Grinder (Tool Only)
Only one whitelisted tester, Pro Tool Reviews, hands-on tested this exact R86040B. PTR scored it 8.2/10, praising cordless mobility and strong cutting torque, but flagged fast battery drain (6-7 cuts per charge) and a single fixed speed with no variable control. (1 sourced review, 1 lab-tested.)
Praised: Cordless mobility and freedom from tangled cords; Strong torque that pushed through steel without backing down; Handy overload-indicator LED and easy tool-less guard adjustment.
Flagged: Fast battery drain; two or three batteries effectively mandatory (6-7 cuts per charge); Single fixed speed with no variable-speed control for precise work; On/off switch tricky with thick welding gloves; spanner wrench not stored on the tool.
