More Information About Glastar's Grinder Bits
All you need to know about Grinding Heads
What makes a tool useful is its ability to simplify a task.

Selecting Proper Grit
Standard grit is 100 mesh, and is well suited for everyday use. Fine grit is 220 mesh and produces a smooth surface with virtually no chipping. For rapid grinding, use the coarse grit of 60 mesh. Glastar 1" and 3/4" heads come in 60, 100, and 220 grit. 1/4", 1/8", 5/8" and our specialty heads come in 100 and 220 grit.
Grinding heads are available in a variety of sizes and styles. First, consider your personal preferences and work methods.

Look for heads that are interchangeable between grinders, task specific and convenient to change. Performance and value are also important.

Grinding heads are made by two methods. The traditional electroplated head is a less expensive choice. However, diamond bonding has been found to outlast electroplated 3:1, making it more cost effective.

Diamond Bonding vs. Electroplating
The diamond-bonding process fuses diamond particles to the grinding heads. The electroplating process encapsulates the diamond particles to the surface.

The PBS Diamond-bonding System ·· eliminates peeling,one of the most common operator complaints. Diamonds are permanently bonded to the head with controlled spacing of the particles making it easier to cool while creating more cutting edges on each particle.

Care & Maintenance
Using Your Heads
Install grinding heads according to directions. Be sure to select the proper grit and size for your project.

When grinding performance becomes unsatisfactory, reposition the head to expose a fresh grinding surface. This technique and the use of a grinding coolant (i.e. Glastar's EZ-Grind™) dramatically extends the life of your heads. For optimum performance, keep the sponge clean by rinsing frequently.

Never grind copper foil, lead came, or plastic with diamond grinding heads. Always check water level before beginning any project.

When to Change
Everyone uses a grinder with different frequency, making it impossible to suggest a replacement rule. If grinding is taking longer, or the head peels (electroplated heads only), it's time for a change.
