Watch this short video to see how the Tormek Truing Tool TT-50 works. You will be able to restore your stone and give it a perfectly round and flat surface within a couple of minutes.
The tool is guided by the Universal Support which also guides the jigs, this ensures that the stone surface is always parallel to the tool fitted in the jig.
TIP If your stone is very uneven, go several times across the stone with a lighter cut rather than a single heavy cut, it will be more efficient. A cut too big can create vibrations in the grindstone.
If your grindstone has become uneven, it is easily fixed with the Tormek Diamond Truing and Dressing Tool TT-50. It will make your stone perfectly round and flat again.
You conveniently feed the diamond cutter across the stone by alternately turning the two knobs with both your hands. Thanks to the controlled feed, you get an even and flat stone surface with no ridges.
The cutting depth is set exactly by the Micro Adjust on the Universal Support. The scale has increments for each 0,25 mm or 0,01". Watch the video for a demonstration on how it works.
With a higher feed speed across the stone (approximately 30 seconds instead of 90 seconds) the surface will have pronounced grooves, which will cause the stone to grind faster. This is beneficial, when sharpening or shaping tools in hard steel with a large bevel area, e.g. turning skew chisels and electric jointer/planer blades.
The slower you feed, the finer the surface you will achieve. A traverse time of 90 seconds across the stone gives you a good finish with hardly any visible grooves.
