Diablo DHS06CFS 6-Piece Steel Demon Carbide Teeth Metal Hole Cutter Set

The Diablo DHS06CFS 6-piece Steel Demon carbide hole cutter set bores clean, burr-free knockout holes through structural steel studs, stainless steel panels, aluminum enclosures, and sheet metal up to 1/4-inch thickness. Engineered with micro-grain TiCo high-density carbide cutting teeth that deliver up to 50X longer cutting life compared to standard bi-metal hole saws, each cutter features an integrated depth stop collar to eliminate work over-penetration. Outfitted with the tool-free Snap-Lock Plus quick-change mandrel system and spring-loaded cobalt pilot bits for rapid core slug ejection, it equips commercial electricians, mechanical contractors, and metal fabricators with precise, non-binding metal drilling performance across hand-held drills and drill presses.

Best Used For:

  • Electrical Panel and Junction Box Knockouts: Drilling precise 7/8-inch, 1-1/8-inch, and 1-3/8-inch conduit pass-through holes in stainless steel and sheet metal enclosures without secondary de-burring.
  • Structural Metal Stud and Framing Penetrations: Slicing utility openings through heavy-gauge steel studs, Unistrut channels, and aluminum framing up to 1/4-inch thick.
  • Mechanical and Automotive Sheet Fabrication: Boring clean, perfectly round holes in truck bodies, ductwork, and structural steel plate with zero material deformation.

Key Performance & Safety Features

  • TiCo Hi-Density Carbide Teeth: Specially formulated micro-grain carbide delivers maximum wear resistance and up to 50X extended cutting life in demanding metal alloys.
  • Integrated Depth Stop Collar: Mechanical shoulder prevents over-drilling beyond the 1/4-inch cutting depth, protecting internal wiring and sensitive components behind panels.
  • Snap-Lock Plus Mandrel System: Patented quick-change mechanism allows rapid, tool-free cutter diameter swaps in seconds with zero thread binding.
  • Spring-Loaded Cobalt Pilot Bits: Heavy-duty cobalt pilot bits resist extreme heat and automatically eject cut metal slugs upon breakthrough.
  • Optimized Tooth Geometry: Carbide teeth slice through steel cleanly to produce smooth, burr-free edges that eliminate the need for manual deburring files.
  • Universal Handheld and Stationary Drill Fit: Heavy-duty 7/16-inch hex shank locks securely into 1/2-inch portable drill chucks and stationary drill presses.
