Aggressive single-segment diamonds designed for fast cutting and efficient concrete preparation.

Ninjas are 16-grit, extra-soft bond metal diamonds built for aggressive concrete grinding and surface preparation.

Their single-segment configuration concentrates grinding pressure into a smaller contact area, helping deliver aggressive cutting action. The extra-soft bond is designed to expose fresh diamond when working on hard, dense concrete.

Ninjas prioritize production speed over maximum tooling lifespan. The objective is to spend less time grinding and keep crews moving to the next stage of the job.

Time costs more than diamonds.

Why Choose Ninjas?

• Aggressive single-segment configuration

• Coarse 16-grit diamond

• Extra-soft metal bond

• Concentrated grinding pressure for fast cutting

• Designed for hard, dense concrete

• Built to expose fresh diamond consistently

• Available individually or in machine-set quantities starting at 9 pieces

• Volume pricing available

The Ninjas Philosophy

The longest-lasting diamond is not necessarily the most profitable diamond.

When a bond is too hard for the concrete, it can glaze over instead of exposing fresh diamond. Cutting performance decreases, grinding takes longer, and labor costs increase.

Ninjas are designed around a different priority:

Cut faster. Spend less time grinding. Keep production moving.

Machine Compatibility

Compatible grinder styles:

• Lavina

• Bartell

• ASL

• Simiron

• Wolfpack

• Common China-style grinders

• Select XPS-style grinders

Compatibility depends on the machine's tooling plate and mounting configuration. Some machines may require adapters.

Husqvarna, Scanmaskin, and SASE machines are not direct-fit applications. Confirm adapter availability and compatibility before ordering.

“Lavina-compatible” describes the mounting style. Ninjas are Bulk Underground aftermarket tooling and are not manufactured, licensed, or endorsed by Lavina or Superabrasive.

Specifications

• Grit: 16

• Bond: Extra Soft

• Segments: One

• Mounting Style: 3-hole Lavina-compatible

Choosing the Correct Bond

The bond determines how quickly the metal matrix wears away to expose fresh diamond.

Extra-soft bonds are generally suited to hard or dense concrete, where harder bonds may glaze and lose cutting efficiency.

Actual performance and wear depend on concrete hardness, grinder weight, operating conditions, and machine configuration. Testing the concrete before selecting tooling is recommended.

Standard machine set: 9 pieces.
