Diablo DHS0563 9/16-Inch Bi-Metal Deep Cut Hole Saw

The Diablo DHS0563 9/16-Inch Bi-Metal Hole Saw delivers high-speed coring across structural dimensional lumber, sheet metal, stainless steel plate, aluminum, and rigid plastics. Engineered with an extended 2-3/8-inch (60 mm) cutting depth, this heavy-duty cup bores through 2x dimensional framing timber in a single pass without needing secondary back-drilling. Its high-speed steel variable tooth design dampens rotational chatter and clears chips rapidly, while full Snap-Lock Plus mandrel integration enables tool-free cup swaps and instant core plug ejection.

Best Used For:

  • Electrical Enclosure & Control Box Knockouts: Cutting clean 9/16-inch pilot holes and auxiliary wire entry ports through sheet steel and stainless enclosures.
  • Plumbing & Mechanical Rough-In: Boring single-pass small-diameter copper tube and control line pass-throughs across 2-3/8-inch thick framing timber.
  • Sheet Metal & Aluminum Fabrication: Drilling precise, chatter-free cylindrical openings in HVAC ductwork and extruded aluminum profiles without edge tearing.

Key Performance & Safety Features

  • 2-3/8-Inch Single-Pass Depth: Delivers 40% deeper cutting capacity to bore entirely through 2x lumber studs and subfloors in a continuous stroke.
  • Variable Tooth Configuration: Alternating tooth pitch geometry minimizes rotational vibration, reduces harmonic chatter, and accelerates chip evacuation.
  • Premium Bi-Metal Construction: High-speed steel cutting edge bonded to an alloy steel backing withstands severe thermal and mechanical friction.
  • Snap-Lock Plus Quick-Change Interface: Mounts instantly onto Diablo Snap-Lock Plus mandrels for fast, tool-free cup changes and one-push core plug ejection.
  • Wide Material Application: Engineered to slice cleanly through hardwoods, softwoods, plywood, mild steel, stainless steel, aluminum, and PVC.
