Can diamond blades be sharpened?
If you’re using a diamond blade correctly, it should sharpen itself as the material you’re cutting will wear the diamond blade away at the perfect pace. However, mistakes are made and you’ll sometimes be using the wrong blade for the material you’re cutting, which means that either the metal in the blade isn’t wearing, or the diamonds aren’t. If the metal isn’t wearing but the diamonds are, then your blade can still be salvaged.
To sharpen your blade, if it’s in this state, all you need is a few minutes, a soft material and a bit of water. You should cut the material while maintaining a steady flow of water to the cut. After a few minutes of cutting, the sharpness of the blade should improve and you’ll start to see the diamonds. Have a quick inspection of your blade to make sure it’s looking sharp and full of diamonds and you’ll be good to go.

Maintaining your tools is important to the quality of your work, longevity of your equipment, and your safety. This is especially important for power tools, which can pose a serious risk of injury if they aren’t operating properly. Keeping your cut off saw blades sharp will prolong the life of your saw by making it easy for a saw to cut and putting less stress on the engine. Safety-wise, this will also help reduce kick-back from the blade snagging.
While diamond blade are designed to essentially sharpen themselves by wearing down and revealing new diamonds, sometimes the diamonds become worn to a point that they become smooth, which doesn’t allow them to be stripped away and the new diamonds to take their place. This typically happens when you have been primarily cutting hard, dense materials. To sharpen the blade and bring expose the new diamonds, follow these steps:
Find a soft, abrasive material that you can make a few cuts into. A concrete block or a brick will work great.
Get a hose and run water over the area of the block you will be cutting. It’s best to have someone hold the hose for you, or secure the hose in a way that doesn’t require you to hold it. Don’t try to hold the hose and cut at the same time.
Make a few cuts into the block or brick while water is running over it. This will create an abrasive slurry that allows the dull diamonds and metal to be stripped away, exposing the new diamonds. You want to be sure you are cutting at least 2 inches into the block so it will wear down the blade enough.
Stop your saw and check the blade after the first few cuts to see if there are exposed diamonds. It’s hard to estimate how long this process will take, since it depends on how dull your saw is, the exact material you’re cutting into, and the blade you are using.
If your blade has reached the steel, it’s time for a new blade. Check your owner’s manual for more information on how to replace the blade and what size and type of blade you need.
How To Dress Or Sharpen A Diamond Saw Blade
In this video, Blake Adsero, Master Wholesale President, shows you how to dress or sharpen a diamond tile saw blade. Diamond Blades that have seen heavy use may not cut efficiently (or at all). Dressing the diamond blade reconditions the tile saw blade by removing glazing debris caused by use, heat, and friction, and re-exposing fresh diamond. The Master Wholesale Rubbing Stone used for dressing diamond blades is available here.
