Sharpening the buttons of your bit with specific grinders and high quality tools increases drilling efficiency and makes you save money and time.
The VS – 220 HD (20,000 PM) grinder is easy to use and is employed with special “Super Diarroc” tools that contemporarily remove part of the bit surface and sharpen the tungsten carbide buttons. Grindings should be done with water flushing or with the bits submerged in water.
The choice of the right “Super Diarroc” tools must be made in accordance with the button size.
