Installing the Grinding Bit

Apply a thin coating of Inland Motor Shaft Lubricant™ (#50022) to the motor shaft. Our Teflon based lubricant helps prevent the bit from seizing on the shaft and seals out ground glass particles. In a pinch, you can use a bit of Vaseline. Loosen the set screw on the 1" WB-9 Grinding Head (D) by turning it counterclockwise with one of the black Allen Wrenches (K). Slide the bit down onto the motor shaft, positioning the set screw over the flat side of the motor shaft. Lower the bit down until just over an 1/8" of silver diamond is exposed above the grid work surface. Secure the bit to the shaft by turning the set screw clockwise with the allen wrench. IMPORTANT: Always secure the bit to the flat side of the motor shaft. Tightening the bit to the rounded side can scar the shaft and prevent bit removal!

Filling the Coolant Reservoir

A water/coolant mix prevents airborne glass dust, increases grinding speed, and prolongs the life of the diamond surface. Remove the Grid Work Surface (B)


and pour water into the reservoir tray until its 2/3 to 3/4 full. IMPORTANT: Never pour water directly onto the grinding head or motor shaft! You can then add a capful of Inland Diamond Coolant (#50011) to increase bit life and grinding speed if desired. Replace the grid surface.

Sponge Placement

sponge placement in BitSertCoolant is fed up to the grinding bit through the yellow Coolant Feed Sponge (E) held in place by the BitSert™ (G). The bottom of the sponge contacts the coolant in the reservoir and the upper portion contacts the diamond surface of the grinding bit. Insert the sponge into the rectangular hole in the back of the BitSert™ so that the bottom of the sponge contacts the coolant in the reservoir and the top of the bit is in contact with the diamond surface of the bit. You may need to wet the sponge before grinding by pouring a small amount of water onto it. The sponge must remain in contact with the bit while grinding. If a white paste develops on the head or your glass when grinding, either the sponge is not properly positioned or the water/coolant level in the reservoir is low. Periodically rinse out the sponge to remove accumulated grinding residue and replace it when it becomes worn.


Turn on the machine and start grind on 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 and check the sponge placement and coolant level. Grinding without coolant greatly reduces the life of your grinding heads.

diamond grinding head positionDiamond Grinding Heads

Diamond grinding heads, or bits, have actual diamond crystals. 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 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 against the flat side of the motor shaft. Reposition the sponge if needed. You have a 5/8" vertical section of usable diamond on 1" and 3/4" diameter grinding bits. Since most stained glass is 1/8" thick, by adjusting the bit up and down on the shaft, you have up to 5 usable sections of diamond before you need to consider replacing the entire bit.


How To Drill A Hole

drilling with diamond grinding headThe Wizard™ comes with a 1/4" grinding/drilling head. The 1/4" WB-8 bit is useful for both drilling holes and intricate grinding. The 1/4" WB-8 is placed onto the motor shaft so it sits on top of the 1" WB-9 head. Loosen the set screw and 

place the bit onto the shaft, securing it to the flat side of the motor shaft like any other bit. You will need to apply coolant to the bit head while drilling using another 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 450 angle, with the coolant soaked sponge held against both the bit and glass. (You may want to use two hands). Start the machine and slowly move the glass down onto the bit to a horizontal position. Continue to work the glass down and around the bit top in a circular motion, making sure to keep the glass and bit surface wet at all times. You may need to stop and reload the sponge several times. Ease up on the pressure as you begin to see the bit come through the back of the glass to help reduce chipping. It is advisable to practice on a piece of scrap glass before you begin drilling on your final project.


Maintenance to your grinder is minimal but important to prolonging the life and performance of the machine.

  1. Motor bearings are permanently sealed and lubricated.
  2. Apply Inland Motor Shaft Lubricant (#50022) to the shaft whenever changing or removing grinding heads. Remove the head if you won't be using the grinder for more than a month.
  3. Tighten grinding head set screws ONLY to the flat side of the motor shaft to prevent scaring the shaft which makes removing the head nearly impossible. Never force a bit onto the shaft and never pry off a bit. If the bit is stuck, contact Inland Customer service for instructions.
  4. Remove and clean the reservoir often. Ground glass accumulates in the reservoir and can slow down the bit and hardened residue is difficult to remove. To remove the reservoir first remove any grinding heads. Lift off the work surface and then lift the reservoir tray off the grinder body. Scrape the glass sludge into the trash and rinse clean. Reassemble the machine (refer to page 2 diagram).
  5. The work surface is reversible. When one side becomes worn, simply flip it over. Replacement grids are available.
