To use Abrasive stones with a mandrel on early versions of GM-08 machines, it is necessary to replace the drive shaft with DL-GM31280
The mandrel for abrasive stones is ordered separately.
With a one-time purchase of an abrasive stone and a mandrel of a stone holder, the kit is supplied assembled with a drilled stone surface. (The cutting of the stone assembly with a mandrel ensures maximum reduction of vibrations during operation and improves the quality of machining parts).
