The Makita GA4542C Corded 4-1/2” SJS II High-Power Angle Grinder incorporates labyrinth construction, a key element in Makita’s design philosophy. This construction creates a complex set of channels that seal and protect the motor, drive gear, and bearings from dust and debris.

These measures form a barrier under rotation, safeguarding the tool from dust and debris penetration, ensuring longer tool life.
