Tormek Stone Grader SP-650 can change the grit size of the Tormek original grindstone to give a finer sharpening surface.
The other side of the Stone grader is used to maintain the grindstone. A coarser grit that will bring new abrasive grains to the surface for an effective sharpening.
The Tormek Original Grindstone is designed so that it can be treated with the Stone Grader to change its quality from fast grinding to fine sharpening.
This has obvious advantages. Once you have created the desired shape on your tool, for example a chisel, you can get an even finer edge using the same grindstone and the same grinding machine with the same jig and settings.
Besides being convenient not having to change equipment, you are guaranteed to get exactly the same edge angle.
If you want the stone to sharpen finer, press the fine side of the stone grader on the grindstone surface for about 30 seconds.
This will alter the surface of the grindstone (220 grit) making it work like a 1000 grit stone.
When you want to go back to the original 220 grit, simply press the coarse side towards the stone for a few seconds until you can notice the stone surface changing.
To keep the grindstone fresh and efficient, use the coarse side of the stone grader when needed.
Press the Tormek STONE GRADER SP-650 firmly with your hands for about 30 seconds.
This process does not place excessive wear on the grindstone and can be repeated any number of times.
