Diablo DHS1875CT 1-7/8" Carbide Teeth Hole Saw is purpose-built to tackle wood and metal in a single, efficient cut. If you’ve faced dull hole saws after a few through-holes or had to switch bits between materials, this carbide-teeth design changes the game—delivering cleaner holes and fewer tool changes on the job.

Cut Wood, Nail-Embedded Wood, Plastic, Aluminum, and Metal—All with One Bit

These carbide teeth hole saws are engineered to slice through a wide range of materials, including nail-embedded wood, plastics, aluminum, cast iron, stainless steel, and various metals. The combination of carbide-tipped teeth and precision geometry means you can punch through tough materials without hesitating or switching tools.

Unmatched Longevity and Speed

Experience up to 50x longer cutting life than traditional bi-metal hole saws. The carbide teeth resist dulling far longer, enabling faster cutting rates and reduced downtime. That translates to more holes per bit and less frustration on demanding projects—from rough carpentry to precision metalwork.

Concrete-Use Scenarios Where This Bit Shines

• Electrical and plumbing installations that require clean, accurate conduit and pipe holes through studs, joists, and metal framing.
• Sheet metal work or fabrications where quick, repeatable hole sizes are essential.
• Rapidly drilling through nail-embedded wood without worrying about snagging or accelerated wear.
• DIY projects that mix wood and metal components, where a single bit keeps your workflow seamless.

Smart Design for Real-World Drilling

With a robust carbide tooth configuration, you get dependable performance even when encountering nails, staples, or other embedded debris. The DHS1875CT is built to maintain a true, round hole and minimizes blade wandering for accurate results. Use with a standard drill and an appropriate arbor to keep your setup secure and stable, especially when starting holes in tougher materials.

Pro Tips for Best Results

• Start with a center pilot bit if your kit includes one to ensure precise alignment and reduce wandering on hard metals.
• Use steady, moderate feed pressure and let the tool do the work—carbide teeth excel when not forced aggressively.
• Apply light lubrication or cutting fluid when drilling metals to dissipate heat and extend tooth life.
• Ensure the workpiece is securely clamped to prevent movement that can chip edges or cause kickback.

Whether you’re a contractor, tradesperson, or serious DIYer, the Diablo DHS1875CT 1-7/8" Carbide Teeth Hole Saw delivers dependable, long-lasting performance across wood and metal projects. It’s not just a hole saw—it’s a single, versatile solution that keeps you moving from material to material with fewer tool changes and cleaner results.
