Unlike freehand sharpening on the grinding wheel, the General Tools drill grinding attachment allowed us to use our bench grinder to sharpen smaller bits effectively. Setup was surprisingly easy ...

Highlights include the mechanism for adjusting the angle of the grind as well as the clever way to slit the body of the attachment so it can be clamped to the nosepiece of the die grinder.

The Rotor Stump Grinder is available in 8 different models, using either power-take off or hydraulics and featuring a drill or cylinder attachment. These grinders can weigh up to 2,500 kg.
