Large disc grinders are the markets where Europe is main, and HITACHI products have obtained high evaluation
in power, durability and quality. However, some improvements are requested to HITACHI's current G 23SC2
series disc grinders because about ten years passed since their development, and the competitors are introducing
high-power products with 2200 W or more input. To correspond to the request for improved powerful products
with 2200 W or more input, the Models G 18SE3, G 18UA2, G 18SG2, G 18UB2, G 23SC3, G 23UA2, G 23SE2
and G 23UB2 have been developed to upgrade and replace the current Models G 18SE2, G 18UA, G 18SG,
G 18UB, G 23SC2, G 23UA, G 23SE and G 23UB. In addition, the Models G 18UA2, G 18UB2, G 23UA2 and
G 23UB2 are equipped with a soft start. The key features of the Models G 18SE3, G 18UA2, G 18SG2, G 18UB2,
G 23SC3, G 23UA2, G 23SE2 and G 23UB2 in comparison with the current models are as follows:
1) 100 W higher input compared to the current models
2) Prolonged service life of the carbon brushes
3) Wear resistance of armature coil
4) Dust-proof labyrinth construction
5) Durable ball bearing retainer of the housing
6) New construction to protect grease leakage
7) Tool-less wheel guard

4-1. Class-top Overload Durability
The Models G 18SE3, G 18UA2, G 23SC3, G 23UA2, G 18SG2, G 18UB2, G 23SE2 and G 23UB2 provide
excellent overload durability thanks to the improved motor winding and carbon brush material in common with the
current models (the service life of the carbon brushes is also prolonged). Figure 1 shows the comparison of
overload durability when the stator coil temperature rise is 200˚K using the Model G 23SC3 as the reference.
As is evident from this, the Models G 18SE3, G 18UA2, G 23SC3, G 23UA2, G 18SG2, G 18UB2, G 23SE2 and
G 23UB2 are superior to the competitors in overload durability.

If the pushing button is pressed while the depressed-center wheel is rotating, the spindle will stop immediately.
In such a case, there is a danger that the wheel nut may be loosened so that the depressed-center wheel flies off
unexpectedly to cause possible serious injury.
