18V Cordless Disc Grinders with Brake System

G18DBBL/G18DBBVL Cordless Disc Grinders with Brake System
  • Lithium-ion Battery
  • Brushless Motor
  • Compatible Batteries
  • Brake System + Slide Switch Suitable for Continuous Operation
Slide switch Electronic brake stops the blade in less than 3 sec when the trigger is released. This allows users to prevent accidents and work much more efficiently.

Wheel washer Use only the wheel washer supplied (No.371677). Please do not use any other ones.

Hitachi Original Brushless Motor Technology

  • ► No wearing parts (carbon brushes, commutator, field coil)
  • ► Hitachi original compact controller
  • Long Lifetime, Maintenance-Free
The brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments. Besides, no carbon brush replacement is required.
  • Compact, Lightweight

  • Variable Speed Control Dial
  • (G18DBBVL only)
Variable speed dial allows users to change the rotation speed to between 4,700 and 9,000/min to suit the application.

  • Deep cutting in concrete
Concrete cutting depth 30mm
  • Dust & Water-Resistant Construction that remarkably increases durability
The resin-coated circuit board protects the electronic components from dust and water.
Note: This series of products is designed to be resistant to dust and water. However, it is not guaranteed that they will not fail. Do not use or leave the products in environments with excessive amounts of dust, in the water or under the rain.

Mesh Filters Mesh Filters
Fine mesh filters significantly improve the dust resistance. The toolless removable filter makes its maintenance easier.
  • Kickback Protection System
monitors a sudden drop in the motor rotation speed and stops the motor quickly to reduce the reaction force (kickback).
Warning Depending on operating conditions, the Kickback Protection System may not work or provide specified performance. Make sure that the workpiece is placed and supported properly, and that the main unit is held firmly during operation.
Additionally, carefully read "KICKBACK AND RELATED WARNINGS" in the instruction manual.
  • Anti-Restart Protection
prevents unintentional restart of the tool for accident avoidance.
  • Soft Start
allows comfortable operation by reducing start-up reaction.

WARNING
CAUTION REGARDING LITHIUM-ION BATTERY TRANSPORTATION
Notify the transporting company that a package contains a lithium-ion battery, inform the company of its power output and follow the instructions of the transportation company when arranging transport.
- Lithium-ion batteries that exceed a power output of 100Wh are considered to be in the freight classification of Dangerous Goods and will require special application procedures.
- For transportation abroad, you must comply with international law and the rules and regulations of the destination country.
