Metabo has released the new Stone Master WE14-125VS 5 grinder. It looks just like every other grinder and does about the same thing as every other grinder, so even with a big, sexy name like WE14-125VS 5, it’s got to be a tough sell — especially since it runs about $200. We see why they put “Stone Master” in front of it.
Metabo stuffed their VTC electronics package in the new grinder — it constantly monitors the motor’s RPM, adding voltage as the load increases, which allows the grinder to maintain the same RPM from no-load to full-rated-load. You can vary the speed from 2,800 to 10,500 RPM.
The WE14-125VS also features Metabo’s “CoolFlow” system — with carbon brushes positioned so they don’t restrict airflow, and a fan that pulls more air through the tool — to keep the 12.2A motor running cooler during operation. With all this technology inside, Metabo claims their grinder’ll last five times longer than other brands.
Here’s the real question: Do the Metabo grinders really last that much longer in your shop, and are they worth the premium to get that longevity? Some guys’ll give you an eager yes and swear by them. Others, who won’t use the grinder enough to justify the cost, opt for a $50 unit instead.
