Customer Questions

Do you stock diamond disks?

We try to keep 8-inch, 10-inch, and 12-inch diamond disks in stock at all times, as these are our most popular disks. However, this depends on how many disks we have to plate for orders and our ability to plate disks for stock. We have two electroplating...

How long will my diamond disks last?

This is possibly the most asked and hardest-to-answer question we receive. Diamond disks are subject to a number of variables that will impact the lifespan of the disk. The main variable is how much glass you are grinding with it. If you're grinding...

I've dropped my diamond disk on its edge, is it destroyed?

It depends. Dropping a diamond disk on its edge is about the worst thing you can do to it, but whether it is destroyed depends on how bad the drop was. If the edge has only slightly crinkled and the electroplating has not detached from the disk, then...

How do I make sure I'm removing the scratches from rougher grits when I work on the finer grits?

There is a very simple way to confirm this. As you are about to remove your piece from the rough grit wheel, hold it in one place for a few seconds so that all the scratches from the rough grit are going in one direction. When you grind your piece ...

My disk is leaving unwanted scratches in my glass, what's wrong?

There is, most likely, nothing wrong with your disk. All of our diamond disks come with a magnetic backing and, as magnets are want to do, they will attract metal objects. Oftentimes, the scratches you are seeing are coming from foreign objects embedded...

What's the best way to store my diamond disks?

Diamond disks can be stored on the flat side of a refrigerator and/or metal filing cabinet (dry the magnet side first). These surfaces are safe storage if they are flat and clean. You might want to let them hang off the edge about a quarter of an inch...

How much water should I use with my diamond disk?

Ah, water, elixir of life and bane of many a coldworker. Water can make or break how well your diamond disks work, and knowing how much water to use for particular steps can be the difference between joy and heartache. Rougher diamond disks like the...

I dropped a piece of glass on my disk, did I damage my disk?

Probably not. A dropped piece of glass is going to happen, at one point or another, to just about everyone. Our Electroplated disks are made strong enough to withstand most of those drops without any problem. You might notice a small ding on the disk...

My piece keeps "grabbing" the disk, especially at finer grits, what's going on?

This is almost always caused by too much water on the finer grits. What's happening is you are hydroplaning on the disk. As you grind, you are floating on top of a layer of water. Occasionally, you will displace enough of the water so your piece will...

How fast should I run my diamond disks?

The speed of your machine will depend on the size of your disk. Remember that diamonds like to run fast and, although you can run them slower, their efficiency will be greatly compromised by slower speeds. Our recommendations for shaft speed are these...

Is there any routine maintenance I should perform on my diamond disk?

Keeping your disk around and in working order for a very long time takes a few routine chores to keep it going. First off is cleanliness. The worst enemy of your diamond disk is glass. "How's that?" you say. Well, when you grind your pieces with your...

Which grits should I purchase? Do I need them all?

Different processes will require different diamond disks. On average, if you are working on pieces that are anywhere from 1 to 3 inches in diameter on the area to be ground, then you can usually start with a 60 or 80 grit for the rough grind (60 grit...

My electroplated diamond disk seems worn out, what can I do?

So your diamond disk isn't running quite the same anymore, and you're ready to toss it out the window? Don't count it out just yet. There is a way to "re-dress" an electroplated disk to get the most possible life out. If your disk is running too slowly...
