The average operation rotation speed of a shaft is between 800 and 2000 RPM causing friction and heat development between flexible shaft casing and the used accessory tool. The sleeve attaches to the end of the flexible shaft casing and acts as a barrier between the rotating accessories and casing.
This prevents damage to the end of the casing and at the same time prevents dirt from getting into the flexible shaft casing. Less dirt between the casing and the shaft ensures better performance and longevity of both the casing and the shaft.
