Diablo DHS5375RL 5-3/8 Inch Bi-Metal Recessed Lighting Hole Saw

The Diablo DHS5375RL is a 5-3/8-inch diameter bi-metal hole saw engineered specifically to bore precise recessed can light mounting openings through drywall, plasterboard, wood ceiling framing, and composite panels. Featuring a 4 TPI variable tooth geometry and a 1-7/10-inch cutting depth capacity, this specialized electrical fixture cutter suppresses vibration to prevent ceiling drywall blowout while accelerating material removal. Complete with a 3-7/20-inch pilot drill bit and tool-free Snap-Lock Plus™ mandrel system compatibility, it allows electricians and ceiling contractors to execute clean, accurately centered can light cutouts with body cut-out slots for direct drilling line sightlines.

• Recessed Can Light Housing Installation: Boring precise 5-3/8-inch ceiling openings through gypsum drywall, plaster, and lathe for flush-mount LED downlights and slim cans.
• Ceiling Joist & Wood Substrate Boring: Coring smooth clearance holes through plywood ceilings, wood lath, and ceiling framing panels during fixture retrofits.
• Acoustical Tile & Plasterboard Cutouts: Slicing burr-free circular openings in drop ceiling tiles and thick drywall without tearing surface paper or cracking plaster edges.

Technical Specifications

Pro-Tip: When cutting recessed light openings in finished ceiling drywall, run your drill motor at medium speed with steady upward pressure and utilize a dust cowl or collection bowl to contain falling gyprock dust and prevent tearing the paper facing.
