Choosing The Right Diamond Blade for Your Saw:
Material Hardness & Aggregate
Diamond blades are manufactured with different segment bonds, ranging from soft to hard. To get the most out of your blade, the bond should be the inverse of the material you’re cutting. Harder materials like granite, stone, or brick cut best with a softer-bonded blade—such as our Brick Ripper—so the bond wears away and exposes fresh diamonds more quickly. Softer materials like asphalt or green concrete require a harder-bonded blade—such as our Boss Blade—to prevent premature segment wear. Also consider the aggregate in the material (flint, limestone, river rock, etc.), as it affects blade life and performance.
Equipment Power & RPM
Your saw’s horsepower directly impacts blade performance and lifespan. Higher horsepower saws often require blades with a higher diamond concentration to withstand the load. Match the blade’s specifications to your saw’s maximum horsepower and recommended operating RPM. Running a blade too fast can cause loss of tension—both a safety hazard and a costly setback.
Cutting Depth Requirements
Know your required cutting depth before selecting a blade to ensure precision and efficiency. Every saw has a manufacturer-set maximum cutting depth based on blade diameter. Check your owner’s manual or our Diamond Blade Cutting Depths Guide. Choosing the correct diameter prevents pushing your blade or saw beyond safe limits.
Wet vs. Dry Cutting
Water cools the blade, reduces dust, and extends blade life—especially during long, continuous cuts. If a blade is wet-use only, it must be used with water to avoid damage and maintain safety. Most dry-use blades can be used either wet or dry, but wet cutting almost always reduces wear and improves cut quality.
Other Key Considerations
Beyond the fundamentals, factor in segment style (segmented, turbo, continuous rim), the cutting environment (indoor/outdoor and dust control), application-specific needs (e.g., ductile iron, porcelain tile), overall blade quality and diamond concentration, and routine safety checks for cracks, worn segments, or damaged cores before use.
Diamond Blade Selection Checklist
Material type, hardness, and aggregate identifiedBond hardness matched to the material (soft bond for hard material; hard bond for soft material)
Saw horsepower and RPM compatibility confirmed
Required cutting depth known; blade diameter selected accordingly
Wet-use or dry-use requirements determined
Segment design chosen (segmented, turbo, continuous) for the application
Diamond concentration and overall blade quality evaluated
Cutting environment considered (indoor/outdoor, dust control, regulations)
Application-specific needs addressed (tile, ductile iron, abrasive block, etc.)
Safety inspection completed (no cracks, damaged segments, or warped cores)
Maximize Cut-Off Saw Performance with the Right Blade
Pairing the right diamond blade with a cut-off concrete saw is crucial for enhancing operator productivity, ensuring precision, and extending the life of both the blade and the equipment. The right blade selection optimizes cutting performance, minimizes downtime, and promotes efficient results in various cutting applications.

Why a Better Diamond Blade Is Worth the Investment
When it comes to cutting concrete, asphalt, or other hard materials, selecting the right diamond blade is one of the most important decisions you can make. With so many options available—ranging from economy to premium grades—it can be tempting to go for the lowest price. But short-term savings often lead to higher long-term costs. The right premium blade improves safety, productivity, and cutting quality while reducing downtime and risk
Kickback Safety: How to Prevent Injuries When Using Cut-Off Saw - General Diamond Blade Safety
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.
