reduce the cost.
2.For the factory who use the angle grinder,the labor cost is the biggest problem.But the brushless angle grinder may can solve
it.For example:when using brushed angle grinders,the factory need 10 people to finish the work while the brushless only need 8
3.Because the brushless angel grinder has a slow brakedown for speed,it can save the disc a lot ,which is about 20%-30%.
4.In the same working conditions,the life for brushless angle grinder expectancy triple than brushed angle grinder.
