Diablo Carbide Hole Saw DHS3250CT 3-1/4 Inch (2-3/8 Cut Depth Snap-Lock Plus Compatible Nail Embedded Wood Stainless Steel Boring Cup)

High-Density 3-1/4 Inch Carbide Tipped Hole Saw with 2-3/8 Inch Cutting Depth Capacity

The Diablo DHS3250CT 3-1/4 Inch Carbide Tipped Hole Saw delivers an industrial multi-material boring solution engineered to drill clean apertures through nail-embedded wood, cast iron, stainless steel, aluminum, and dense composites. Featuring high-performance carbide teeth that provide up to 50 times longer cutting life than standard bi-metal hole saws, this heavy-duty cutting cup incorporates an expanded 2-3/8 inch cutting depth to bore through thick structural timber and double-stud bays in a single pass. Designed for integration with the Snap-Lock Plus Mandrel System, the assembly enables rapid tool-free cup changes and fast core plug ejection to minimize contractor downtime on commercial rough-in jobs.

Best Used For:

• Plumbing & Electrical Rough-Ins: Boring 3-1/4-inch pipe penetration holes through nail-embedded framing studs, joists, and floor plates.
• Metal Conduit & Plate Penetration: Drilling clean cable and conduit pathways through stainless steel junction boxes, aluminum panels, and cast iron pipes.
• Thick Structural Framing: Executing deep single-pass cuts through multi-ply engineered wood, heavy lumber, and composite deck boards.

Key Performance & Safety Features

• High-Performance Carbide Teeth: Proprietary carbide tip formulation delivers 50X longer cutting life compared to traditional bi-metal hole saws.
• Expanded 2-3/8 Inch Cutting Depth: 60mm deep cup profile bores through 2x dimensional lumber in a single pass without stopping to clear cores.
• Snap-Lock Plus Mandrel System: Quick-change connection mechanism facilitates tool-free cup swaps and eliminates thread-seizing under heavy torque.
• Tool-Free Plug Ejection: Side slot geometry allows fast, effortless core removal without using screwdrivers or prying tools.
• Multi-Material Cutting Tooth Design: Optimized tooth geometry shears aggressively through both soft wood fibers and tough ferrous metals.

Technical Specifications

Pro-Tip: When drilling through thick stainless steel or cast iron plates, run your drill at a lower RPM and apply steady, continuous pressure while using cutting fluid. This prevents thermal hardening of the metal and keeps the carbide teeth cool to maximize blade life.
