The AGC is smooth and predictable for cutting, deburring and finishing. Variable speed gives it an advantage on heat-sensitive materials and jobs where full speed is unnecessary.
Festool’s vibration isolation makes longer sessions less tiring. The tool feels composed and the quick-release nut speeds up changes between cutting and grinding discs.
Who is it for?
It suits fabricators, fitters and existing Festool users who value refinement, control and dust-resistant construction over budget pricing.
Final verdict
The AGC 18-125 is expensive but exceptionally refined. It is the strongest choice here for users prioritising control and comfort.
