The Best First Grind Steps for Diamond Disks

GREAT BEGINNINGS

When working with diamond disks, it's very important to know which grit is the right starting point for the type of glass you are working. If you start too rough, you'll chip and possible break your glass; if you start too fine, then you'll prematurely wear out your disk and replace them more often than necessary. Finding the right balance can make all the difference in how your diamond grinding process improves your work efficiency.

GET ROUGH

If you're working larger surface areas or removing a lot of material, starting with a rougher grit like 60 or 80 grit is preferable. 60 grit will remove more material but give more edge chipping while an 80 grit will give less edge chipping but wear out faster for larger surface areas or more material removal. For large amounts of removal or very large surface areas, consider moving down to a 45 or 30 grit for heavy removal. If large sections can be removed by saw cuts this will help your diamond disks last longer.

AIM FOR MIDDLE GROUND

For fused glass edges and smaller work, a mid range diamond disk is always the best place to start. A 100 or 140 grit is a great choice for dealing with smaller surface areas or pieces that don't require much removal and just need a quick flattening. Rougher grits will cause too much edge chipping on thinner glass and remove too much material from smaller surfaces. Mid range grits are the best starting points for these types of pieces.

YOU'RE SO FINE

With thinner glass and smaller surface areas, it is often preferable to start with a finer grit disk like a 200, 270, or even 325 grit. Thinner glass will require less aggressive diamonds to remove material without chipping the edge as it works and small surface areas like millefore and murrini can often be easily cleaned up after a saw cut with a 200 or 270 grit diamond disk.
