Genuine 4 Rotor BHR242 BHR243 DHR242 Rotary Hammers

The Makita 619737-4 is a genuine OEM rotor for the brushless motor in compatible Makita SDS-Plus rotary hammers, providing a direct like-for-like replacement when the original component is worn or damaged. Built around a precision steel shaft and magnet assembly, the rotor forms the rotating core of the motor and is responsible for transferring power efficiently to the hammer mechanism. Factory-correct dimensions ensure proper motor alignment is maintained, helping to restore drilling speed, impact consistency, and smooth running after installation. As a genuine Makita part, it is engineered to the same tolerances as the original component, meaning fit and performance are assured without compromise. This is particularly important in demanding applications such as continuous concrete drilling, masonry work, and structural renovation, where motor integrity directly affects tool reliability and output. Compatible with the Makita BHR242, DHR242, BHR243, and DHR243 rotary hammer platforms, this rotor is the correct choice for contractors and repair technicians looking to extend tool service life and minimise downtime on site. It replaces OEM part numbers 619737-4, 619293-4, and 6192934.
