Thanks to ultra-powerful brushless motor durability and stability have improved.

 There is no carbon powder emission and maintains a clean environment.
Significant durability improvement considerably reduces maintenance cost.
Reduces the temperature rise of the motor by about 30% and mitigates problems related to heating.
Two types of start systems (push and lever) are available with one screwdriver (not applicable to BL-2000).
High-speed rotation shortens the tightening time and improves work efficiency.
