Diablo DHS08SCTR 8-Piece Demo Demon Carbide Rough-In Hole Saw Set

The Diablo DHS08SCTR 8-piece Demo Demon carbide teeth rough-in hole saw set bores large-diameter utility openings through nail-embedded lumber, roof shingles, fiber cement siding, and clean dimensional wood. Engineered with high-performance carbide teeth that deliver up to 50X longer cutting life and 5X faster material removal compared to standard bi-metal hole saws, each cup features an extended 2-3/8-inch cutting depth to cut 2x timber in a single pass. Outfitted with the patented SnapLock PLUS quick-change mandrel system, two high-speed pilot bits, and tool-free core plug ejection, it equips residential plumbers, commercial electricians, and HVAC mechanics with rapid, non-binding utility rough-in boring across handheld and right-angle drills.

Best Used For:

  • Plumbing Drainage and Vent Rough-Ins: Boring 2-1/8-inch to 4-5/8-inch clearance holes through floor joists and wall studs packed with framing nails and construction screws.
  • Electrical Junction and Conduit Passages: Slicing clean service entries through fiber cement exterior panels, roof decking, and wood siding without tooth fracturing.
  • HVAC Duct and Flue Penetrations: Cutting wide utility runs through multi-layer asphalt shingles, structural sheathing, and dense engineered lumber.

Key Performance & Safety Features

  • High-Performance Carbide Teeth: Micro-grain carbide formulation resists abrasive wear to deliver up to 50X longer operational life in severe multi-material substrates.
  • Extended 2-3/8-Inch Cutting Depth: Provides 40% deeper single-pass drilling capacity to bore completely through 2x dimensional framing timber without stalling.
  • SnapLock PLUS Mandrel Interface: Patented quick-change mechanism enables tool-free cup size swaps in seconds with universal fitment across 5/8-inch to 6-inch hole saws.
  • Tool-Free Plug Ejection: Aggressive side slot geometry allows operators to clear dense wood cores and composite plugs quickly with a standard screwdriver.
  • Aggressive Tooth Geometry: High-speed rake design shears through heavy timber and exterior building composites with 5X faster boring velocity.
  • Universal Drill Compatibility: Robust 7/16-inch hex shank locks firmly into standard 1/2-inch three-jaw chucks and heavy-duty right-angle rough-in drills.

Pro-Tip: When roughing in pipe holes through floor joists embedded with framing nails, maintain a steady drill speed and hold the tool firmly perpendicular to the wood grain; letting the carbide teeth grind through the embedded steel without forcing the cut preserves the tooth braze joints.
