A simple 12V sharpener for keeping chains cutting between workshop sharpens. The G712 Sharp-N-Ezy runs at 14,000rpm straight off a car or ute battery and sharpens any size or brand of chain: change the stone to suit the pitch and set the height gauge.

Includes a 1/4in stone for lowering depth gauges. Sharpening stones for your chain are sold separately: see Granberg Grinding Stones. For more speed and fan cooling, step up to the G1212 Grind-N-Joint.
