Diablo DHS2250CT 2-1/4-Inch Carbide Teeth Deep Cut Hole Saw

The Diablo DHS2250CT 2-1/4-Inch Carbide Teeth Hole Saw delivers multi-material cutting through nail-embedded wood, cast iron, structural steel, and stainless steel. Designed with an extended 2-3/8-inch cutting depth, this cup bore penetrates 2x dimensional lumber in a single pass without binding. The heavy-duty carbide teeth provide up to 50 times longer cutting life compared to conventional bi-metal hole cutters, while the integrated Snap-Lock Plus system enables tool-free cup swaps and core plug ejection.

Best Used For:

  • Plumbing Pipe Rough-In: Drilling clean 2-1/4-inch clearance holes through framing joists and studs for drain lines and copper supply pipes.
  • Electrical Conduit Penetration: Boring through steel service enclosures, sheet metal ductwork, and structural wall plates in a single pass.
  • Remodeling Through Nail-Embedded Stock: Cutting through reclaimed lumber, dense plywood subflooring, and framing fasteners without stripping cutting teeth.

Key Performance & Safety Features

  • High-Performance Carbide Teeth: Delivers up to 50X longer cutting life compared to bi-metal saws in abrasive materials and hard metals.
  • Deep 2-3/8-Inch Cut Depth: Allows single-pass cutting through standard 2x lumber, eliminating the need to clear material from both sides.
  • Snap-Lock Plus Mandrel System: Quick-change arbor design enables rapid cup changes and effortless tool-free plug ejection.
  • Optimized Tooth Geometry: High-strength brazed carbide tips cut aggressively through wood, cast iron, plastic, and stainless steel.
  • Heavy-Duty Steel Body: Rigid cylindrical barrel maintains concentric rotation to produce true, round holes under high torque drill loads.
