Diablo DHS11SLD 11-Piece Snap-Lock Plus Bi-Metal Deep Cut Hole Saw Set
The Diablo DHS11SLD 11-piece bi-metal hole saw set bores large-diameter utility penetrations through dimensional lumber, structural metal studs, plastic conduit, cast iron pipe, and stainless steel sheet. Engineered with high-performance bi-metal cutting cups, a deep 2-3/8-inch (60 mm) cutting depth for 40% deeper single-pass boring, and an anti-vibration variable tooth geometry, this kit eliminates multi-pass cutting delays. Outfitted with the tool-free Snap-Lock Plus quick-change mandrel system, two high-speed pilot bits, and rapid core plug ejection slots, it equips commercial plumbers, electricians, and mechanical contractors with fast, versatile hole drilling across all standard hand drills and drill presses.
Best Used For:
- Plumbing Drainage and Vent Rough-Ins: Boring 2-1/8-inch to 4-3/4-inch utility holes through 2x dimensional floor joists and subflooring in single passes.
- Electrical Panel and Conduit Pass-Throughs: Slicing clean entry holes in stainless steel junction boxes, aluminum enclosures, and heavy metal studs without tooth strip-out.
- HVAC and Mechanical Pipe Penetrations: Cutting wide ducting and insulated pipe runs through nail-embedded wood, plywood decking, and PVC wall panels.
Key Performance & Safety Features
- Snap-Lock Plus Mandrel System: Enables quick, tool-free cup size changes and universal fitment across all Diablo hole saws from 5/8-inch to 6-inch diameters.
- 2-3/8-Inch (60 mm) Deep Cup Design: Bores 40% deeper than standard 1-1/2-inch hole saws, cutting completely through 2x dimensional lumber in a single stroke.
- Variable Pitch Tooth Geometry: Aggressive alternating tooth pattern slices wood and dense metal with reduced vibration and faster cutting speeds.
- Tool-Free Plug Ejection: Oversized side slots allow rapid core extraction with a screwdriver, minimizing jobsite downtime between holes.
- Heavy-Duty Bi-Metal Metallurgy: Electron-beam welded high-speed steel cutting edge delivers extreme durability in abrasive metals and nail-embedded timber.

Pro-Tip: When drilling large diameters like 4-1/8" or 4-3/4" into stainless steel or structural metal studs, drop drill speed to low RPM and apply steady, firm pressure with cutting fluid; this prevents work-hardening the metal and preserves the bi-metal tooth matrix.
