The Granberg G1012XT 12V Electric Chainsaw Sharpener is the bar-mounted electric grinder for arborists, loggers, and chainsaw mill operators who need to dress chain teeth in the field without taking the chain off the saw. The 12-volt motor runs off a vehicle outlet, a portable jump pack, or any 12V deep-cycle battery — the head clamps to the chainsaw bar and uses a grinding stone to restore the cutter angle in seconds per tooth.
The G1012XT is the same principle as the bench-mount sharpeners but sized for portable use: the motor head pivots on the bar so each cutter is hit at the same angle, the depth gauge sets the grinding pressure, and the operator works through every cutter in 5-10 minutes rather than packing up the saw and driving to a bench. Replacement grinding stones are stocked at most chainsaw dealers and ship from Granberg’s parts catalog.
Granberg has manufactured chainsaw sharpening systems in Richmond, California since 1955 — the G1012XT carries Made in USA designation per the manufacturer’s listing. Pair this sharpener with a Granberg Alaskan MK-IV mill so the chain stays sharp through long slabbing sessions where dull teeth would slow the cut and burn the lumber.
