Diamut CNC Breaker Bits

Remove bulk material faster and dramatically extend the life of your CNC profile wheels.

Looking for a CNC Breaker Bit That Saves Your Profile Tooling?

Diamut CNC Breaker Bits are designed to remove the majority of material before your profile wheels begin shaping the edge. By roughing the stone first, these aggressive breaker bits reduce the workload placed on expensive CNC profile wheels, helping extend tooling life while improving fabrication efficiency.

Using a breaker bit before profiling also helps prevent profile wheels from developing the common groove that forms in the center over time. This allows your shaping wheels to maintain their intended profile longer, resulting in more consistent edges, lower tooling costs, and higher-quality finished countertops.

Available in both single and double breaker bit configurations, Diamut Breaker Bits are engineered for professional fabrication shops working with granite, quartz, quartzite, and other natural or engineered stone materials. Both versions feature a 120mm diameter and are suitable for machining 2cm and 3cm material, while the double breaker bit is also recommended for 4cm laminated edges.

Why Use a CNC Breaker Bit?

Profile wheels are designed to shape and finish countertop edges—not remove large amounts of material. By using a breaker bit first, fabricators remove excess stone quickly while allowing profile wheels to perform only their intended shaping operation.

This process significantly reduces wear on expensive profile tooling, improves profile consistency, and minimizes the formation of grooves that can negatively affect finished edge quality. The result is longer tooling life, lower operating costs, and increased productivity throughout the fabrication process.

Whether you're producing standard countertop edges or complex laminated profiles, Diamut CNC Breaker Bits help maximize CNC efficiency while protecting one of your shop's most valuable tooling investments.

Frequently Asked Questions

What is a CNC breaker bit used for?

A CNC breaker bit removes the majority of material before the profile wheel begins shaping the countertop edge, improving efficiency and extending tooling life.

Why should I use a breaker bit before my profile wheel?

Removing excess material first reduces wear on your profile wheels, helps prevent grooves from developing in the tooling, and produces more consistent finished profiles.

What is the difference between the single and double breaker bits?

Both feature a 120mm diameter for 2cm and 3cm material. The double breaker bit is also the preferred choice for machining 4cm laminated edges.

What materials can Diamut CNC Breaker Bits be used on?

They are commonly used on granite, quartz, quartzite, and other natural and engineered stone materials processed on CNC fabrication equipment.

How do breaker bits improve fabrication efficiency?

By quickly removing bulk material before profiling, they reduce machining time, protect expensive profile tooling, and allow the CNC process to run more efficiently from roughing through finishing.
