Keep your clipper running at peak performance with the genuine ANDIS Blade Drive Assembly (Part No. 20658/20659). This essential component powers the detachable blade motion on AG, AGC, AGR, and BG-style clippers. When blades stop cutting smoothly or vibrate excessively, a worn blade drive is often the cause. Replace every 30–60 days (depending on use) to restore smooth operation and extend your clipper blades life. Add Blade Screws to your order!
