Introducing the Diablo DHS2375CT 2-3/8" Carbide Teeth Hole Saw for Wood and Metal — a game-changing tool that pairs carbide durability with cross-material cutting. Designed to tackle wood, nail-embedded wood, plastic, aluminum, and tough metals, these hole saws redefine efficiency on the job site by delivering up to 50x longer cutting life than traditional bi-metal options.

Why carbide teeth matter: the wear resistance of carbide keeps teeth sharp longer, even when you encounter nails, coatings, or hard metals. That means fewer bit changes, cleaner holes, and less downtime, so you can finish more projects in less time. The DHS2375CT’s geometry is engineered to minimize grabbing and heat build-up, helping you maintain control and achieve precise circle cuts every time.

Materials you can cut with confidence

• Wood and nail-embedded wood
• Plastic and aluminum
• Metal, including cast iron and stainless steel
• General-purpose metal work up to the 2-3/8" diameter

Key advantages that boost productivity

• 2-3/8" hole diameter — ideal for electrical boxes, plumbing, and conduit runs
• Carbide-tipped teeth for extended life and faster cutting versus bi-metal holes
• Efficient chip evacuation and reduced clogging for cleaner holes
• Optimized tooth design minimizes binding and preserves hole quality
• Compatible with standard drill chucks and most drill motors for easy setup

Who benefits most

Ideal for electricians and plumbers who frequently encounter mixed-material openings, carpentry and trim installers working with nail-prone framing, and ambitious DIYers tackling projects that blend wood and metal components. If your work involves hard metals or nail-studded wood, this is the hole saw that stays sharper longer and gets the job done faster.

Practical tips for best results

• Mark the center and start with a light pilot guide to ensure accurate alignment.
• Feed steadily and avoid forcing the tool through stubborn materials—let the carbide teeth do the work.
• When cutting metal, apply a little lubrication and use slower speeds to minimize heat buildup.
• Regularly clean the teeth after use to prevent pitch or debris from dulling cutting edges.
• Use with a compatible drill and steady clamp or base to maintain hole accuracy on larger projects.

With the Diablo DHS2375CT, you gain a versatile, durable hole saw that delivers reliable performance across wood and metal tasks. This isn’t just about making holes—it’s about making precise, long-lasting holes more quickly and with less effort, so you can move from project to project with confidence.
