Lenox 308011200P 1200P 17-Piece Bi-Metal Plumber's Speed Slot® Hole Saw Kit

The Lenox 308011200P 1200P 17-piece bi-metal plumber's hole saw kit drills, bores, and penetrates clean cylindrical openings through carbon steel, cast iron, stainless steel, structural timber, drywall, and PVC piping. Engineered with proprietary T3 Technology featuring optimized tooth geometry, these heavy-duty hole saws deliver up to 50% longer cutting life and faster material penetration across 12 essential plumbing diameters ranging from 3/4-inch up to 4-1/2 inches. Outfitted with split-step pilot drill bits that eliminate pre-drilling and reduce bit binding, staircase Speed Slot® cutouts for rapid plug removal, standard 2L and 5L universal arbors, and a rugged transport case, it equips commercial plumbers, pipefitters, and electrical contractors with high-efficiency hole cutting endurance across all construction materials.

Best Used For:

• Commercial and Residential Plumbing Rough-Ins: Boring clean clearance holes through wood studs, floor joists, and subfloors for copper water supply lines, PVC drain-waste-vent (DWV) piping, and PEX tubing.
• HVAC and Mechanical Pipe Penetrations: Cutting through sheet metal plenums, furnace cabinets, and electrical junction enclosures without tooth stripping or binding.
• Structural Steel and Cast Iron Boring: Drilling clean holes in low carbon structural steel plates, iron framing, and metal studs using step-tip pilot bits without walking or grabbing.

Key Performance & Safety Features

• Proprietary T3 Toothform Technology: Advanced tooth design cuts construction materials efficiently while delivering up to 50% longer blade lifespan compared to standard bi-metal hole saws.
• Patent-Pending Step Bit Pilot Drills: Stepped tip design starts holes on contact without pre-drilling, preventing aggressive saw slamming and yielding up to 50% fewer pilot bit breaks.
• Staircase Speed Slot® Plug Ejection: Wide, tiered slot design allows screwdrivers to gain multiple leverage points for instant wooden and metal slug removal.
• Universal Arbor Compatibility: Fits both quick-change and traditional non-quick-change standard 1/4-inch shank arbor systems without requiring special adapters.
• High-Speed Steel Cutting Edge: Electron-beam welded M42 high-speed steel cutting teeth bonded to an alloy steel backing withstand high cutting temperatures and mechanical impact.
• Comprehensive Plumber Sizing Range: Includes 12 dedicated trade diameters tailored to standard pipe, conduit, and tubing outside dimensions from 3/4-inch to 4-1/2 inches.
