Notes

Festool's TPC 18/4 QUADRIVE is a premium cordless drill/driver known for a multi-gear drivetrain and precision ergonomics. "Clicking" in 4th gear often points to gearbox wear or a chipped gear tooth-repairs that can be costly because parts and labor are specialized.

Repair is most sensible when the tool is relatively new, the issue is confined to the gearbox, and the rest of the system (chuck, clutch, electronics) is healthy-especially if you rely on Festool ecosystem accessories and service. Replacement becomes more attractive when the tool is older, shows symptoms across multiple gears, or has repeated drivetrain service history.

Price used reflects a typical new purchase price from authorized-tool retailers; basic/bare configurations and kit versions vary, so compare against the exact package you would replace.
