ONCEPT AND MAIN APPLICATIONS
Model DJR186 is a Cordless recipro saw powered by 18V Li-ion battery and
has been developed for higher cutting efficiency and
more durability than the current models DJR181/ DJR182 by adopting
Vertical crank mechanism and reviewing specifications.
Its main features are:
• Ergonomically designed handle
• High durability thanks to more rigid shoe and durable mechanism
to support slider
• Toolless blade change
• Enhanced performance of cutting speed and stroke length
• Vertical crank mechanism minimizes blade deflection and reduces
vibration to machine.
• Two-finger switch trigger
Note: BL1815 is not compatible.
