Diablo DHS5000 5" Bi-Metal Hole Saw is engineered for speed, depth, and dependable performance on demanding job sites. Designed to tackle thick materials with confidence, this hole saw delivers not just holes, but a faster, cleaner way to work.

Built with a true bi-metal construction, the DHS5000 blends hardened cutting teeth with a durable backing to handle wood, metal, and composite materials in a single, versatile tool. The 5-inch diameter opens substantial openings for conduit, plumbing, electrical work, and venting, while an extended cutting length lets you bore deeper holes in one pass—cutting downtime and boosting productivity.

Why this design stands out

• Fast, tool-free mounting with a purpose-built mandrel – The integrated hole saw system and mandrel design simplify attachment, so swapping bits on busy job sites is quick and secure.
• Tool-free plug ejection – After the cut, the plug ejects without needing extra tools, reducing cleanup and keeping you moving to the next hole.
• Variable Tooth Design – Aggressive start-to-bite geometry delivers faster cuts and smoother finishes across different materials, from metal to wood.
• Ultimate cutting length – Deep-hole capability means fewer passes and less material handling when you need significant bore depth.

Ideal use cases

Perfect for electricians installing conduit through studs and metal panels, plumbers routing large-diameter openings in thick stock, or fabricators drilling through steel, aluminum, and hardwood. The 5" diameter and deep-cut capability make it a reliable choice for challenging installations where precision and speed matter.

Practical guidance for best results

• Pair with a compatible mandrel for secure mounting and easy bit changes.
• Keep a steady feed rate and apply light lubrication when cutting metal to minimize heat and wear.
• Start the cut with a pilot guide or center mark to maintain alignment, especially on denser materials.
• Clear debris promptly with the plug-ejection feature to prevent jams on repeated holes.

With the DHS5000, you’re not just drilling holes—you’re accelerating installations, reducing tool changes, and achieving consistently clean, accurate results across a range of materials.
