Not all diamond blades are created equal---and we're not just talking about size or segment shape. One of the most important (but often overlooked) factors in blade performance is the bond type.

If your blade is wearing out too fast or not cutting efficiently, chances are you're using the wrong bond for the material.

In this guide, we'll break down soft, medium, and hard bond diamond blades, what they're designed for, and how to choose the right one for your next job.

What Is A Diamond Blade Bond?

The "bond" in a diamond blade refers to the metal matrix that holds the synthetic diamonds in place. As the blade cuts, the bond slowly wears away, exposing fresh diamond edges to continue cutting efficiently.

Bond hardness determines how fast this matrix wears down---and that determines how effective the blade is on specific materials.

Understanding Bond Types

Soft Bond Blades

• Best For: Hard materials like cured concrete, granite, natural stone, or porcelain tile
• Why: The softer matrix wears down quicker, exposing new diamonds faster to cut tough surfaces
• Risks If Misused: Wears too quickly on soft materials

Medium Bond Blades

• Best For: General-purpose use, masonry, brick, pavers, and moderately abrasive materials
• Why: Offers balanced wear rate and diamond exposure across a wide range of surfaces
• Risks If Misused: Less efficient on extremes (super hard or soft surfaces)

Hard Bond Blades

• Best For: Soft, abrasive materials like asphalt, green concrete, limestone, or block
• Why: The harder matrix resists wearing too quickly when cutting crumbly or sandy material
• Risks If Misused: Glazing or dulling on hard surfaces due to slow diamond exposure

What Happens If You Use The Wrong Bond?

Using the incorrect bond can lead to:

• Excessive blade wear
• Slow or inefficient cutting
• Glazing (diamonds aren't exposed)
• Overheating and warping
• Chipping or blade failure

Choosing the right bond for your material is critical---not just for performance, but also for blade lifespan and user safety.

How To Choose The Right Bond

Ask yourself:

1. What material am I cutting?
   Harder materials = softer bond. Softer materials = harder bond.
2. Will I be cutting wet or dry?
   Wet cutting allows more aggressive bond usage by controlling heat.
3. What's my cutting depth and speed?
   Deep, fast cuts may require more durable bonds with excellent heat resistance.
