Note :

2. Other dimensions are available on request.
 
Cautions:
 
1. Make sure the hole size is suitable for the spindle of grinder, when installing, to prevent from unnecessary runout or surface deviation of diamond wheel.
2. It is better to use in wet condition with coolant, not only to extend the wheel life, but also to restrain the flying of cutting dust and get a better surface finishes
3. When operating, keep the wheel face either parallel or vertical to the working material and wear necessary prevention mask and eye goggles.
4. If the diamond wheel becomes dull or loaded, use WA or GC abrasive stone to dress the wheel surface to regain its grinding ability.
