Meet the Diablo DHS4500 4-1/2" Bi-Metal Hole Saw—a new standard in fast, reliable opening for a range of materials. Built to elevate productivity, this hole saw combines aggressive cutting performance with smart design that makes setup and use noticeably easier.

• Deeper holes in a single pass: The extended cutting length is engineered to bore deeper without re-drilling, saving time on electrical, plumbing, and carpentry projects.
• Bi-metal construction for durability: Tough, long-lasting teeth paired with a resilient body stand up to demanding materials while maintaining sharp cutting edges.
• Variable Tooth Design for faster cuts: Optimized tooth geometry reduces binding and accelerates material removal, delivering cleaner holes with less effort.
• Tool-free plug ejection: Quick, hassle-free removal of the plug means less downtime and a smoother drilling workflow.
• Effortless attachment with a dedicated system: Diablo’s hole saw system and mandrel design streamline mounting, so you’re ready to drill in moments and stay secure during use.

Designed for professionals who demand speed and reliability, the DHS4500 is ideal for electricians, plumbers, metal workers, and woodworkers tackling repeated 4-1/2" openings. Its innovative features translate into tangible benefits: faster project turnaround, fewer tool changes, and cleaner results from first hole to last.

• electrical rough-ins, conduit and box openings, plumbing penetrations, HVAC work, and cabinetry installations where precise, consistent 4-1/2" holes are required.
• busy job sites, where time savings add up across multiple openings and when drilling through mixed materials that demand a robust, versatile hole saw.
• pair with a compatible arbor, maintain steady feed pressure, and choose the appropriate drill speed for the material to maximize cutting efficiency and prolong tooth life.

Experience a hole saw that prioritizes real-world performance: faster cuts, easier setup, and durable, dependable operation with every hole you bore. The Diablo DHS4500 4-1/2" Bi-Metal Hole Saw is built to help you finish more work in less time, with results you can trust on every project.
