With brushless angle grinder , this excess weight is simpler to control which aids the user complete their occupation much more efficiently.
This modifying of route does get a unique bearing so not torque or speed is lost in the transfer of motion. This is completed with the angle bearing. When correctly greased, this system works flawlessly. The issue arises when the seal at the stop of the shaft exactly where the disc is mounted is worn or damaged. Grinders by mother nature get off modest bits of debris that can trigger injury to a bearing of this variety. A near inspection prior to every single use could avert premature use on this part.
