Diablo DHS2125CT 2-1/8 Inch Carbide Teeth Wood and Metal Hole Saw

The Diablo DHS2125CT is a 2-1/8-inch diameter carbide teeth hole saw engineered to bore deep clearance openings through nail-embedded wood, cast iron, stainless steel, aluminum, plastic, and sheet metal. Featuring high-performance carbide-tipped teeth and an extended 2-3/8-inch cutting depth capacity, this multipurpose cutter delivers 40% deeper single-pass holes compared to standard bi-metal options. Compatible with Diablo's Snap-Lock Plus™ quick-change mandrel system and 1/4-inch minimum drill chucks, it enables plumbers, electricians, and HVAC technicians to drill door hardware prep holes and pipe pass-throughs with up to 50 times longer tool life in tough materials.

  • Door Lockset & Deadbolt Installation: Boring standard 2-1/8-inch lockset face holes through solid wood doors, steel entry doors, and composite materials.
  • Plumbing & Drainage Pipe Pass-Throughs: Slicing clean clearance openings through floor joists, subfloors, cast iron stacks, and metal framing studs for 1-1/2-inch PVC lines.
  • HVAC & Electrical Enclosure Boring: Executing smooth, multi-material circular cuts through metal ducts, stainless steel junction boxes, and nail-embedded timber headers.

Key Performance & Safety Features

  • High-Performance Carbide Teeth: Premium carbide tooth matrix provides up to 50X longer cutting life in high-tensile metals and abrasive materials compared to bi-metal saws.
  • Extended 2-3/8-Inch Cutting Depth: Extra-deep barrel allows single-pass cutting through 2x dimensional lumber, thick wall assemblies, and multi-layered materials.
  • Snap-Lock Plus™ Mandrel Compatibility: Connects directly to tool-free mandrel systems to enable rapid cup swaps without requiring separate adapters.
  • Tool-Free Plug Ejection Slots: Specialized side slot design facilitates fast core plug removal using a screwdriver to minimize jobsite downtime.
