Why Q-Drive® Blade Technology?
Decades of testing and refinement have created the most advanced dustless cutting system available.
Cool Cut Technology
The integrated vacuum keeps the blade cool by removing debris before it can be reground, reducing friction and heat buildup.
Fully Integrated System
Every blade is engineered to work with a specific iQ saw and material. Not generic. Not one-size-fits-all.
Longer Blade Life
Less heat, less friction, and purpose-built bond formulas mean your blade lasts longer and cuts better.
OSHA Compliant
Q-Drive blades work with iQ's dust collection system to keep silica exposure below OSHA limits.
Q-Drive® Blade Anatomy
Every Q-Drive blade is engineered with precision components working together for maximum cutting performance and dust collection efficiency.
Segmented Rim Design
Gullets (cooling slots) between diamond segments enhance airflow and cooling for fast, aggressive cutting in masonry and concrete.
Continuous Rim Design
Solid edge provides chip-free cuts in delicate materials like porcelain tile, ceramic, and glass for smooth, precise results.
Silent Core Technology
Laser-welded copper core reduces vibration and noise for smoother, quieter operation on select Q-Drive blades.
Bond Selection
Softer bonds for harder materials (high PSI), harder bonds for softer materials. Matched to maximize blade life and performance.
Diamond Saw Blade Basics
No matter if you are a tile installer, mason, or hardscaper; there are four main categories that each contractor should understand about diamond saw blades. These categories include Diamond Patterns, Tension, Bond, and more. Understanding the basics of diamond saw blades will help you choose the best option for your job and get the job done faster.

Find the perfect match between saw, blade, and material

Blade Testing
At iQ, we understand that finding the perfect match between the saw, the blade, and the material is crucial. Blade choice is important as it affects the machine and potentially ruins its motor if the wrong blade is used. The bond, diamond pattern, and segment number all play a role in selecting the right blade.
Additionally, PSI (pound per square inch), which is the hardness level of materials, is also an important factor to consider. The higher the PSI, the harder the material and the softer the bond of the diamond blade should be. Knowing the hardness of the aggregates in your material helps in selecting a blade best suited for your job. Furthermore, it's essential to recognize that different regions around North America have varying aggregates in their materials, and just because a label says 'concrete diamond blade' doesn't mean it's the best option for the material to be cut. Knowing the material variations and PSI levels can help select the right blade for the material and improve efficiency.
Composition of a Q-Drive Diamond Blade
Hard vs Soft Bond
The bond (or metal matrix of a diamond saw blade) is the glue that holds the diamonds in place. It is a mixture of three or more different metal powders pressed together at a high temperature. The hardness of the bond determines what the blade should be used for and its lifespan, as well.
Arrayed vs Random
Diamond blades use diamond crystals mixed into the blade segment to maximize precision cutting through the material. The pattern of those diamonds determines the rate at which they will grind.
Silent Core
Copper or steel? What's at the core of your blade? Most diamond masonry blades used for concrete block cutting have a steel core which makes a high pitch ringing noise when cutting. However, some blades have a copper core. The copper acts as a silencer and reduces the DBA of that blade.
Tension
Blade tension is a vital aspect to consider. If not monitored correctly, users can lose it by forcing a blade through the material faster than it would naturally cut it.

Blade Maintenance
How to Condition Your Blade
When cutting with a new blade, make 25 or more cuts through scrap materials like standard medium-hard ceramic or medium-hard concrete to open up the diamond matrix. This will optimize the blade for cut quality and performance.
Make Sure to Test Your Blade
Not sure of the PSI of your material? Not sure if the glazing will chip? Then test it. Make some test cuts and then see what blade cuts that material the cleanest, before you start a project. Work smarter and plan ahead.
Dressing the Blade
Dressing the diamond blade is essential to maintaining its life. After a large number of cuts, or when switching from different materials, dressing the blade will remove build-up on the segments, and expose fresh diamonds, allowing your blade to cut sharper and faster without putting pressure on the saw motor.
How to Dress Your Diamond Blade
Dressing your diamond blade is essential to maintaining blade life and cutting performance. After a large number of cuts — or when switching between different materials — the blade can begin to glaze over with built-up material. Dressing removes that build-up and exposes fresh diamonds so the blade cuts sharper, faster, and with less strain on the saw motor.
When to Dress
- Slower cutting speed
- Increased resistance while cutting
- The blade is glazing or polishing instead of cutting cleanly
- You've switched to a different material and performance drops
How to Dress
- 1Use an iQ dressing stone appropriate for your blade/application.
- 2Start the saw and bring the blade to full operating speed.
- 3Make several controlled passes through the dressing stone.
- 4Use light, steady pressure. Do not force the blade.
- 5Check cutting performance.
- 6If the blade is still cutting slowly, make a few additional passes until performance improves.
Why It Matters
- Remove glazing and segment build-up
- Restore cutting speed and efficiency
- Expose fresh diamonds for cleaner cuts
- Reduce unnecessary load on the saw motor
- Extend overall blade life
