Segmented Blade: The Complete Guide to Diamond Segmented Blades for Concrete, Masonry, Stone, and Construction Cutting

A segmented blade is one of the most widely used cutting tools in the construction, masonry, concrete, stone fabrication, demolition, and hardscape industries. Designed for aggressive cutting performance and exceptional durability, segmented blades are engineered to cut through some of the toughest materials encountered on construction jobsites.

Whether cutting reinforced concrete, cured concrete, brick, block, pavers, asphalt, granite, natural stone, or masonry products, segmented diamond blades deliver fast cutting speeds, superior cooling, and long service life. Their unique segmented rim design allows contractors to achieve maximum productivity while maintaining excellent cutting performance in demanding applications.

Professional contractors, concrete cutters, masons, hardscape installers, utility crews, and demolition specialists rely on segmented blades because they provide a combination of cutting speed, durability, and versatility that few other blade types can match.

What Is a Segmented Blade?

A segmented blade is a diamond cutting blade that features individual cutting segments separated by gaps known as gullets.

Unlike continuous rim blades, which have an uninterrupted cutting edge, segmented blades utilize separate diamond segments attached to a steel core.

These segments contain:

• Industrial diamonds

• Metal bonding materials

• Specialized cutting compounds

The gaps between the segments serve several important functions:

• Improve cooling

• Remove debris

• Increase airflow

• Reduce heat buildup

This design makes segmented blades ideal for aggressive cutting applications where speed and durability are critical.

How a Segmented Blade Works

Segmented blades cut by using industrial-grade diamonds embedded within each segment.

As the blade rotates:

1. The diamonds contact the material.

2. Microscopic particles are removed.

3. New diamonds are exposed as the bond wears.

4. Cutting continues efficiently.

The gullets between segments help:

• Release dust

• Improve airflow

• Prevent overheating

• Enhance cutting speed

This process allows segmented blades to maintain performance even under heavy workloads.
