DIAMOND SANDING DRUMS
User Instructions

Inland is the only saw and shaper manufacturer that makes their own diamond sanding drums. Because each drum is 100% microscopically inspected, we guarantee your absolute satisfaction. Inland sanding drums fit all machines with a standard motor shaft.

Safety

1. Always wear proper eye protection when sanding or drilling.
2. Gloves are recommended for hole drilling.

Installation

1. It is always a good idea to apply a lubricant such as Inland to the motor shaft whenever installing or changing drums. This helps prevent the drum from seizing on the shaft and keeps ground glass and debris from getting down into the motor.
2. Loosen the set screw using the allen wrench provided.
3. Place the drum onto the shaft so that the set screw sits over the flat side of the motor shaft and diamond is exposed above the work surface.
4. Secure the bit to the shaft by tightening the set screw.
5. When the exposed diamond no longer sands efficiently, loosen the set screw and move the bit up on the motor shaft to expose a fresh section of diamond.

Drilling Holes

 You can use the smaller drilling bits, like 1/8" sanding drums or the drilling  drums for sanding intricate details and tight curves as well as drilling holes. These drums are generally installed on top of the larger 3/4" and 1" drums.

1. Install the drum onto the motor shaft following the instructions above. You may need to lower the bottom drum to expose enough shaft to secure it.
2. Hold the material between your thumb and middle finger. If you are shaping or drilling mineral based materials, you need to also have a coolant soaked piece of sponge between your forefingers to keep the diamond wet.
3. Bring the material down onto the drum at about a 45° angle where you want the hole drilled.
4. As you drill, work the material around the point of contact with the drum as you raise it to a level position. Continue working the material around the drum. If you are wet drilling, check frequently to make sure you have enough coolant in the sponge to keep the drum wet. When you are about to come through the back of the material, reduce the downward pressure to help prevent excessive chipping as the head comes through the material.

Helpful Hints

1. If a white powder forms around the drum as you wet grind or drill, check the coolant reservoir adding coolant if needed and/or make sure the sponge is properly contacting the reservoir and bit. NEVER GRIND MINERAL BASED MATERIALS DRY!
2. Always tighten drums to the flat side of the motor shaft. Tightening to the round side can scar the shaft and prevent the drum from being removed.
3. Remove drums if you are not using the machine for long periods.
