Carbide vs. Bi-Metal: What’s the Difference? 

At a glance, both get the job done. But they’re built for different conditions, ensuring you get the right cut every time.  

When to Choose Carbide: 

When the job gets tougher, carbide is where you want to be. Ideal for jobs that entail cutting through abrasive, multi-material assemblies. With industrial carbide teeth, they deliver faster cutting speeds in tougher applications while maintaining clean, controlled holes for professional results. A thick-wall steel body adds strength and stability, helping the tool hold up under demanding conditions. The result is longer tool life, especially in exterior wall work, and a lower cost per hole over time when working in challenging materials.
