The Hitachi G 18DBAL W4 is a compact, brushless cordless grinder that when combined with Hitachi's extremely efficent 18v li-ion batteries, becomes as powerful as a standard AC powered machine that uses 115mm diameter discs with a 22mm bore and also features a popular and helpful Paddle Switch.
Having a brushless motor makes the G 18DBAL W4 one of the most ligthweight and compact 18v grinders around. The new and improved motor doesn't have any carbon brushes in it, so energy from the battery is not wasted on generating unwanted heat or friction. Because of this we get slightly more power out of our batteries, and also a vast increase in runtime and overal liftime of the battery
Aside from the newer, more efficent motor its also features a soft start function, allowing you to start a job with greater accuracy which is complemented by an 'anti-restart' function with prevents the accidental start up of the machine.
Theres also a new handy paddle switch which allows users to easily turn the grinder off and on without having to change grip.
There's also 'AUTO' mode function
Its the first cordless grinder in the industry to be equipped with Hitachi's AUTO mode meaning that this grinder intelligently adjusts its speed of rotation depending on the material its cutting. This machine optimises itself for whatever job its doing, meaning that your disc, grinder and battery are all used as efficently as possible.
Hitachi G 18DBAL W4 is compatible with all Hitachi's Li-ion 18v Batteries: from 1.5Ah - 5Ah
