Glass Grinders: Wizling & Glastar

Never run diamond grinder bits dry. Diamond grinder bits are designed to be used with a lubricant, such as water, and will be ruined immediately if used dry. Always make sure you are using adequate water while grinding so that the material’s dust doesn’t form. This dust contains chemicals that can be hazardous to your lungs if inhaled and is known to cause cancer, birth defects or other reproductive harm. To reduce your exposure to these chemicals, work in a well ventilated area and wear a face or dust mask. Never grind more than one workpiece at a time. Some materials contain poisonous elements. Avoid grinding materials that contain uranium, mercury, lead, arsenic, etc. Make sure you know the material you are grinding.

Grinding Turn on the machine and start grinding a piece of scrap glass to get a ‘feel’ for the grinding action. Begin by pushing the glass into the grinding bit using light pressure and moving the glass back and forth across the bit. Slowly increase the pressure until you feel comfortable with the grinding speed and your control. You’ll quickly learn the optimum grinding pressure for the types of glass you use. When grinding out deep cuts, use intermittent pressure to allow coolant to rinse ground glass from the head. If you ever have a white paste form on the bit, it is not getting enough coolant. Stop, turn off the machine, and check the sponge placement and coolant level. Grinding without coolant greatly reduces the life of your grinding heads. As the diamond surface wears, you will feel it grind less effectively. When this happens, it is time to expose a new portion of the diamond surface. Loosen the set screw using the included Allen wrench and move the grinding head up on the shaft to expose a new 1/8“ section of diamond. Secure the bit back in place making sure to tighten the set screw against the flat side of the motor shaft. Reposition the sponge if needed. You have up to 5, 1/8” sections of exposed diamond on a standard grinding bit to use before you need to consider replacing the entire head.

How to drill a hole in glass The WizCG comes with a 1/4“ grinding/ drilling bit. It is not included with the WizlingCG. This 1/4” grinder bit is useful for drilling holes and intricate grinding. The 1/4“ bit is placed onto the motor shaft and sits on top of the 3/4” grinder bit. Loosen the set screw with the included Allen wrench, then slide the bit onto the shaft, securing the set screw to the flat side of the motor shaft. You need to supply the coolant to the 1/4“ bit while drilling by using the other included sponge soaked in coolant. Begin drilling the hole by holding the front surface of the glass against the upper edge of the bit at about a 45° angle, while holding the coolant soaked sponge against the bit and glass (Fig. D). You will want to use two hands. Slowly move the glass down onto the bit in a horizontal position. Continue to work the glass down and around the top of the bit in a circular motion, making sure to keep the glass and diamond wet at all times. You may need to stop and soak the sponge with coolant several times. Reduce pressure as you begin to see the bit come through the back of the glassto avoid chipping. Practice before you drill your final project.
