Diablo DHS1750CT 1-3/4 Inch Continuous Depth Carbide Teeth Hole Saw

The Diablo DHS1750CT is a 1-3/4-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 contractors to drill conduit pass-throughs, pipe clearance openings, and metal enclosure knockouts with up to 50 times longer tool life in high-tensile substrates.

Best Used For:

  • Plumbing & Drainage Pipe Pass-Throughs: Slicing clean 1-3/4-inch clearance openings through floor joists, subfloors, cast iron stacks, and metal framing studs for 1-1/4-inch PVC drain lines and copper piping.
  • Electrical Panel & Metal Enclosure Knockouts: Cutting smooth, burr-free entry ports through stainless steel junction boxes, aluminum cabinets, and structural metal studs.
  • HVAC Ducting & Timber Header Boring: Executing multi-material circular cuts through sheet metal ductwork and dense nail-embedded wood framing in a single pass.

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.
  • Universal Substrate Versatility: Engineered to cut seamlessly across clean timber, nail-embedded wood, cast iron, stainless steel, aluminum, and PVC.
