Diablo DHS1750CT 1-3/4" Carbide Teeth Hole Saw for Wood and Metal redefines drilling versatility. These carbide-tooth hole saws are the first on the market designed to cut both wood and metal—including nail-embedded wood, plastic, aluminum, cast iron, stainless steel, and other metals. Built to outperform traditional bi-metal options, they deliver up to 50x longer cutting life and noticeably faster cutting performance, helping you get more work done in less time.

Why the DHS1750CT stands out

• Carbide teeth for multi-material cutting: Engineered to slice through wood, nail-embedded wood, plastic, aluminum, metal, cast iron, and stainless steel with precision.
• Exceptional durability: Up to 50x longer cutting life than conventional bi-metal hole saws, reducing replacements and downtime.
• Faster, cleaner cuts: Aggressive tooth geometry designed for rapid material removal while maintaining hole accuracy.
• 1-3/4" diameter: Perfect for standard electrical, plumbing, and HVAC installations, as well as DIY projects that demand a precise 1.75-inch hole.
• Versatility in one accessory: Eliminates the need to switch between different hole saws when moving between wood and metal tasks on a single project.

Ideal for who and when to use

• Electricians, plumbers, carpenters, and HVAC installers who frequently encounter mixed-material workpieces.
• Remodelers dealing with nail-embedded framing, metal ductwork, or metal panels where a clean, correctly sized hole is essential.
• DIY enthusiasts tackling home projects that require drilling through wood and metal without swapping tools.

Practical use cases

• Routing conduit and wiring through wooden studs and metal components without changing bits.
• Cutting openings in metal electrical boxes, brackets, or thin-gelted metal sheets as part of a larger build or repair.
• Creating precise holes in plastic and aluminum panels for hardware installation or venting solutions.

Tips for best results

1. Use a sharp pilot bit and maintain steady feed pressure to maximize carbide performance and hole quality.
2. Match drill speed to material: start with a moderate speed when cutting wood, and reduce speed when transitioning into metals to minimize heat buildup.
3. Keep the workpiece securely clamped to prevent wandering and to ensure consistent hole placement.
4. Clear debris frequently during cutting to maintain efficiency and prolong tooth life.

With the Diablo DHS1750CT, you don’t have to choose between wood and metal cutting. This 1-3/4" carbide teeth hole saw delivers durable, rapid performance across a range of materials, making it a smart, time-saving addition to any toolkit. Whether you’re outfitting a professional trades setup or tackling a mixed-material project at home, this hole saw is built to keep up with demanding jobs and help you finish projects faster.
