When your diamond blade starts sparking, slowing, or skipping, it’s probably glazed. The metal bond has sealed over the diamonds, stopping them from cutting. The good news? You can bring it back to life in minutes with the right tools and a steady hand.
What You’ll Need
Before you start, get the essentials ready:
Dressing stone (or a cinder block if you’re stuck on-site)
Water or coolant system for wet saws
Safety gear — goggles, gloves, and ear protection
Your diamond blade, mounted and ready to go
Step 1: Check the Blade
Start with a quick inspection. If you see cracked segments, missing pieces, or wear down to the core, grab a new blade.
If the blade just looks shiny or glazed, a quick dressing will fix it.
Step 2: Set Up the Dressing Block
Place the dressing stone on a flat, stable surface right in the saw’s cutting path. Keep it steady but not clamped too tight.
When cutting dry, use light pressure. For wet saws, make sure your water flow runs steady before starting.
Step 3: Dress the Blade
Now it’s time to bring those diamonds back.
Turn on the saw and gently lower the blade into the dressing stone. Make smooth passes forward and back — three to ten cuts usually do the trick.
Each pass exposes fresh diamond edges and clears away the metal glaze.
Pro tip: Don’t rush it. Let the blade work naturally. Too much pressure can glaze it again before you’re done.
Step 4: Check and Clean
Stop the saw and look closely at the edge. You should see a rougher, sharper surface where fresh diamonds stand out.
If it still feels slick or cuts slow, make a few more passes.
When it’s cutting clean again, rinse and wipe the blade before storing it.
Step 5: Keep It Cutting Smooth
Regular maintenance keeps your work fast and consistent. Dress your diamond blades every few weeks — or whenever cutting slows — to maintain performance.
When switching between different concretes or materials, change blades to match the job. The right bond and segment save time, effort, and money.
