Diablo DHS14SGP 14 Piece Bi-Metal Snap-Lock Plus Hole Saw Set
The Diablo DHS14SGP 14-Piece General Purpose Bi-Metal Hole Saw Set functions as a high-speed rotational wood and metal boring kit engineered to drill pass-through holes for plumbing pipes, electrical conduits, and HVAC ducting. Built with premium bi-metal cutting cups paired with a tool-free Snap-Lock Plus mandrel, this 14-piece system provides a 2-3/8-inch (2.375 in.) cutting depth across hole diameters ranging from 7/8 inch up to 2-9/16 inches. Outfitted with variable tooth geometry, plug ejection slots, pilot drill bits, adapter nuts, and a molded storage case, this 6.6-pound set enables single-pass drilling through 2x dimensional lumber, structural plastics, aluminum, and sheet metal plates.
Best Used For:
- Plumbing Pipe & Conduit Penetrations: Boring clean 2-9/16-inch holes through floor joists and wall studs to run schedule 40 PVC and copper water lines.
- Electrical Box & Cable Rough-In: Cutting 7/8-inch to 1-3/8-inch clearance holes through metal framing and wood studs for electrical conduit and Romex cabling.
- HVAC & General Structural Boring: Drilling through 2x dimensional lumber, sheet metal ductwork, fiberglass panels, and plastics with a single continuous pass.
Key Performance & Safety Features
- 2-3/8 Inch Extended Cutting Depth: 2.375-inch cup depth clears standard 2x dimensional lumber in a single continuous pass without stopping to remove wood plugs.
- Snap-Lock Plus Mandrel Connection: Tool-free quick-change mechanism allows rapid swapping of hole saw cup sizes without thread adapters or pin alignments.
- Tool-Free Core Plug Ejection: Side slot configuration permits operators to remove jammed wood and metal plugs quickly without using screwdrivers.
- Low-Vibration Variable Tooth Geometry: Aggressive tooth pitch clears chips rapidly while dampening torque feedback to improve rotational stability.
- Universal Bi-Metal Substrate Capacity: High-speed steel bi-metal compound cuts cleanly through hardwoods, softwoods, plastics, aluminum, and sheet metal.
- Zero-Wobble Mandrel Interface: Threadless locking mechanism eliminates arbor play to protect drill chucks and extend pilot bit service life.

Pro-Tip: When using the larger 2-9/16-inch hole saw cups in the Diablo DHS14SGP set to bore through thick hardwoods, ease up on forward drilling pressure every 1/2 inch to let the variable teeth throw out accumulated wood chips. Clearing debris reduces friction heat, preserves tooth sharpness, and speeds up deep wood cuts.
