Why Router Bits Matter in Cabinet Door Manufacturing: Diamond vs. Carbide Explained

When it comes to large-scale production of American-style cabinet doors, one tool is absolutely indispensable: the router bit. But what do factories actually mean when they talk about diamond bits and tungsten carbide bits? Let’s break it down.

Diamond Router Bits: Longevity and Performance

As the name suggests, diamond bits are valued for their exceptional hardness and durability. On average, one diamond bit can process up to 20,000 meters of wood, which is equivalent to roughly 10,000 cabinet doors. This makes diamond bits the go-to choice for long production runs, ensuring consistent quality and efficiency.

Tungsten Carbide Router Bits: Practical and Affordable

By comparison, tungsten carbide bits have a shorter lifespan. A typical tungsten carbide bit can process about 7,000 meters of wood, or approximately 3,500 cabinet doors. While they don’t last as long, their biggest advantage is cost: they are priced at only about 10% of a diamond bit. This makes them highly suitable for samples, prototypes, or small custom projects where large-scale durability isn’t necessary.

Choosing the Right Tool for the Job

So, which option is better? The answer depends on your project. For high-volume production, such as orders exceeding five shipping containers, diamond bits are the smart investment. For small-batch or custom work, tungsten carbide bits provide flexibility at a fraction of the cost.

At the end of the day, there’s no “perfect” product—only the right tool for the right purpose.
