Diablo DHS09SGPCT 9-Piece General Purpose Carbide Teeth Hole Saw Set

The Diablo DHS09SGPCT 9-piece general purpose carbide teeth hole saw set bores clean conduit openings through electrical enclosures, drills rough-in plumbing pipe penetrations through 2x4 framing, slices stainless steel panels, and cores dense plastics without tool binding. Engineered with TiCo™ high-density carbide teeth that deliver up to 50X longer cutting life than standard bi-metal hole saws, this kit provides an extended 2-3/8-inch cutting depth to core 40% deeper holes in a single pass without stopping to clear timber plugs. Outfitted with the patented Snap-Lock Plus™ mandrel system for tool-free cup size transitions and instant core ejection, along with an aggressive variable tooth geometry that dampens vibration and frictional heat, it equips commercial plumbers, electricians, and mechanical contractors with fast, burr-free boring across 3/8-inch and 1/2-inch drill chucks.

Best Used For:

  • Electrical Service and Conduit Rough-In: Boring 1-inch to 2-inch entry holes through steel junction boxes, panel knockouts, and aluminum raceways with clean, burr-free edges.
  • Plumbing Pipe and Mechanical Chases: Drilling through dimensional framing lumber, subflooring, and hidden nails in a single pass to route water supply lines and drain pipes.
  • Stainless Steel and Cast Iron Fabrication: Coring holes in dense metal sheets, machinery enclosures, and cast metal without dulling or stripping carbide teeth.

Key Performance & Safety Features

  • TiCo™ Hi-Density Carbide Teeth: Specially formulated micro-grain carbide tips withstand severe abrasion from wood resins, steel fasteners, and dense metals.
  • Extended 2-3/8-Inch Cutting Depth: Delivers 40% deeper cutting reach to complete single-pass boring through 2x dimensional lumber without plug removal delays.
  • Patented Snap-Lock Plus™ Mandrel: Enables fast, tool-free cup changes and effortless plug ejection with a quick backward push on the collar.
  • 50X Extended Cutting Life: High-performance carbide metallurgy outlasts standard bi-metal hole saws by up to 50 times in multi-material drilling.
  • Variable Tooth Geometry: Dual-pitch tooth configuration balances chip load to reduce high-torque rotational vibration and heat accumulation.
  • Universal Mandrel System: One Snap-Lock Plus mandrel body securely fits all Diablo hole saw diameters ranging from 5/8 inch to 6 inches.
