Introducing the Diablo DHS5500 5-1/2" Bi-Metal Hole Saw — a purpose-built solution for professionals who demand speed, durability, and precision when drilling through a variety of materials. Built on Freud/Diablo’s trusted Bi-Metal platform, this hole saw delivers noticeably faster cutting performance and upgraded productivity compared to traditional options.

• Bi-Metal construction combines tough breaker teeth with a flexible backing, extending life and enabling clean, aggressive cuts through wood, plastics, and soft metals.
• 5-1/2" diameter with maximum cutting length designed to bore deeper holes in a single pass, reducing the number of passes and downtime on the job.
• Innovative hole saw system and mandrel design simplify attachment, enabling fast, secure mounting with minimal setup—perfect for busy job sites.
• Tool-free plug ejection clears debris and plugs quickly, so you stay productive without stopping to clear the workpiece.
• Variable Tooth Design delivers faster, cleaner cuts by optimizing tooth geometry for each stage of the cut, reducing gumption and heat buildup.

What makes the DHS5500 truly stand out is Diablo’s integrated system approach. The combination of a robust mandrel, a user-friendly mounting process, and a tooth geometry engineered for efficiency means you’ll spend less time swapping bits and more time finishing holes. Whether you’re installing electrical boxes, running conduit, or creating access holes in paneling and structural material, this hole saw is built to handle demanding jobs with dependable results.

Ideal use cases

• Electrical installations requiring large-diameter perforations in hollow or solid sections
• Plumbing work where quick, accurate holes through studs or sheets are needed
• Carpentry and remodeling projects involving precise penetrations in wood and composite materials
• Fabrication tasks that involve soft metals or plastic panels where clean edges matter

Who should consider the DHS5500? Professionals who value speed without sacrificing accuracy, DIYers tackling ambitious projects, and anyone updating their toolkit with a robust, long-lasting hole saw that won’t bottleneck the workflow. This is a decisive upgrade from standard hole saws, designed to deliver deeper holes, smoother edges, and faster changes on the job.

Tips for best results: pair the DHS5500 with a compatible mandrel for secure mounting, use steady feed pressure, and maintain a light touch to minimize heat buildup on metal surfaces. For optimal longevity, drill with a modest cutting speed and let the tooth geometry do the work.
