Diablo DHS1125CF 1-1/8 Inch Steel Demon Carbide Hole Cutter

The Diablo DHS1125CF is a 1-1/8-inch diameter carbide teeth hole cutter engineered to bore precise, burr-free knockouts through sheet metal, stainless steel, steel studs, and electrical panels. Equipped with TiCo™ Hi-Density carbide teeth and an integrated 1/4-inch depth stop collar, this professional sheet metal cutter prevents over-penetration to safeguard internal electrical wiring and components. Featuring a spring-loaded cobalt pilot bit and tool-free plug ejection via Diablo's Snap-Lock Plus™ mandrel system, it delivers up to 50 times longer cutting life in high-tensile metals compared to standard bi-metal hole saws using handheld drills or stationary drill presses.

Best Used For:

  • Electrical Panel Knockout Boring: Cutting clean 1-1/8-inch conduit entries in steel breaker boxes, junction enclosures, and control cabinets without damaging internal wiring.
  • Stainless Steel & Sheet Metal Fabrication: Coring smooth, burr-free holes through tough stainless steel panels, structural ductwork, and steel framing studs.
  • Plumbing & Mechanical Pipe Pass-Throughs: Slicing accurate clearance openings through metal studs, copper plates, and iron sheets during commercial retrofits.

Key Performance & Safety Features

  • TiCo™ Hi-Density Carbide Teeth: Formulated carbide teeth deliver 50X longer cutting life and extreme heat resistance in hard metal substrates.
  • 1/4-Inch Depth Stop Collar: Mechanical stop shoulder limits drilling penetration to 1/4-inch depth to protect interior components and prevent bit binding.
  • Spring-Loaded Cobalt Pilot Bit: Premium cobalt starter bit centers cuts accurately while the ejector spring automatically pushes out metal slugs.
  • Snap-Lock Plus™ Mandrel Compatibility: Connects directly to tool-free mandrel systems to enable rapid cup swaps and instant slug ejection.
  • Optimized Tooth Geometry: Shearing tooth alignment reduces cutting friction to produce clean, burr-free edges without requiring filing or deburring.
  • Universal Machine Compatibility: Operates efficiently across 1/4-inch chuck handheld power drills, impact drivers, and stationary drill presses.
