The grease inside cordless drills and impact drivers can reach temperatures of 200°F (93°C) during heavy use, which is why manufacturers use special high-temperature greases. Regular household greases would break down and leak out of the gearbox within minutes under these conditions. This extreme heat comes from the tiny, high-speed gears spinning at thousands of RPM while transferring huge amounts of torque. Many DIY enthusiasts don't realize their handheld tools generate temperatures similar to a car engine.
