Cut Further, Faster: Solutions to Common Diamond Blade Issues
Maximize your blade life and improve efficiency by addressing these common diamond blade issues. Learn how to prevent damage, enhance performance, and cut with confidence.
Loss of Tension
A diamond blade experiencing "loss of tension" is out of alignment, causing it to wobble during cutting. A blade with this issue must be re-tensioned before use.
Causes & Prevention:
• Incorrect RPM: Ensure your saw's RPM matches the blade's maximum RPM.
• Dropped or Mishandled Blade: Handle with care—store in its box or hang it on a hook.
• Overheating from Excessive Force: Let the blade cut naturally without added pressure; use step-cutting when needed.
⚠ Do not use a blade until it has been re-tensioned!
Segment Loss
Diamond blades have laser-welded segments attached to the core. If the weld weakens, segments may break off, making the blade unsafe.
Causes & Prevention:
• Material Shifting: Secure your material to prevent movement during cutting.
• Twisting While Cutting: Lift the blade out of the cut before changing direction.
• Excessive Force: Let the blade do the work. If the cut isn’t smooth, back off and reassess.
⚠ Never continue using a blade with missing segments!
Cracked Segments
A cracked segment appears as a small fracture. If ignored, it can lead to complete segment loss.
Causes & Prevention:
• Too Much Pressure: Avoid forcing the blade into the cut.
• Incorrect Blade for Material: Use a blade with the proper bond hardness for the material.
⚠ Stop using the blade immediately if a segment is cracked!.
Overheated Blade
Overheating causes a bluish discoloration on the blade core and segments, leading to potential segment loss or core cracks.
Causes & Prevention:
• Insufficient Water Supply: Maintain a consistent water flow to produce a slurry with a chocolate milk consistency.
• Excessive Pressure: Let the blade cut at its own pace without forcing it.
Excessive Segment Wear
If your blade wears out faster than expected or wears unevenly, it may be due to improper use.
Causes & Prevention:
• Incorrect Blade Selection: Use the correct bond hardness for the material.
• Insufficient Water Supply: Ensure adequate cooling to prevent accelerated wear.
Glazed-Over Segments
Glazing occurs when a blade's cutting segments lose exposed diamonds, making them feel smooth and unable to cut effectively. You can redress a glazed blade to restore cutting performance.
Causes & Prevention:
• Incorrect Blade Selection: Use a blade with the proper bond hardness.
• Incorrect RPM: Verify your saw operates within the blade’s recommended RPM range.
• Excessive Water Use: Maintain a proper coolant balance—aim for a chocolate milk consistency.
• Blade Spinning in Wrong Direction: Ensure the arrow on the blade matches the cutting direction.
Cracked Core
A cracked core typically starts in the gullet and can be extremely dangerous, potentially sending pieces flying at high speeds.
Causes & Prevention:
• Forcing the Blade in Tight Cuts: Let the blade cut naturally without excessive pressure.
• Insufficient Water Supply: Maintain proper water flow to keep the blade cool.
⚠ Never use a blade with a cracked core!
Undercutting
Undercutting occurs when the blade’s core wears faster than its segments, often due to abrasive materials and improper cutting techniques.
Causes & Prevention:
• Abrasive Material Wear: Maintain proper water flow to control slurry.
• Cutting Too Deep: Use step-cutting techniques to reduce strain on the blade.
⚠ Stop using a blade if it is undercut!

Cut-Off Saw Kickback Prevention and Diamond Blade Safety Tips
Reactive forces can occur any time a cutting wheel is spinning. The same power that lets a blade chew through concrete, asphalt, or pipe can work against you if the wheel slows or stops. When a wheel binds or pinches, those forces can act instantly and throw the saw out of your control, which can lead to serious injury.
Best Blades for Masonry Cutting: Top Diamond Blades for Brick, Block, and Hard Materials
If you’re cutting brick, block, pavers, or hard masonry on the job, the right diamond blade makes a big difference. The right blade cuts faster, tracks straighter, and holds up longer, which means fewer blade changes and fewer headaches.
Segmented vs. Turbo vs. Continuous Rim Diamond Blades: Which One Should You Use?
If you’ve ever stood in front of a blade rack wondering which diamond blade to buy, you’re not alone. The biggest difference between common diamond blade types comes down to the rim design:

Abrasive Cut-Off Saw Wheels: How to Use Them Safely
Abrasive cut-off saw wheels are a common tool on jobsites, especially for cutting steel and masonry. When they’re used and handled correctly, they’re effective and reliable. Most problems don’t come from the saw itself. They come from damaged wheels, improper storage, or using the wrong wheel for the RPM of the saw.
