Bore 40% Deeper Holes in One Single Pass with the Tool-Free Snap-Lock Mandrel System
Drill through thick structural lumber, engineered wood studs, metal framing, fiberglass panels, and plastic conduits with the versatile cutting force of the Diablo DHS14SGP 14-Piece General Purpose Bi-Metal Hole Saw Set. Engineered specifically for professional electricians, plumbers, HVAC technicians, and general contractors, this industrial-grade master kit entirely reformats structural boring workflows. Standard bi-metal hole saws offer shallow cutting margins and lock plugs tightly inside the metal cup, forcing you to freeze work and use screwdrivers to pry out stubborn wood plugs. This advanced Diablo tool kit resolves that field bottleneck by featuring a massive 2.375-inch cutting depth paired with a tool-free plug ejection framework, allowing you to slice clean apertures through 2x dimensional lumber in a single continuous pass.
Uncompromising speed and dynamic structural durability form the foundation of this elite 14-piece wood and metal boring set. Built with premium bi-metal cups and a specialized variable tooth configuration, these saws minimize vibration harmonics and deliver blazing-fast clean cutting paths without walking. The heart of this set is the proprietary Snap-Lock Plus™ mandrel system, allowing you to swap cup sizes in seconds without dealing with threaded adapters or secondary pin assemblies. Whether you are running hole diameters from 7/8-inch up to 2-9/16-inch to feed schedule 40 pipe or routing electrical box conduits, this high-performance system ensures a tight, zero-wobble connection to protect your drill chuck while maximizing jobsite productivity.

Pro-Tip: When cutting deep holes through heavy sheet metal plates or dense structural framing with these bi-metal hole saws, always slow your drill motor down to a lower RPM setting and apply a generous coat of cutting fluid or threading lubricant to the work surface. High speed creates massive thermal friction against the bi-metal teeth, which can dull or strip the tooth profile. Maintain steady, firm pressure and pull the hole saw back slightly every few seconds to clear wood chips or metal filings out of the deep cup channel. This clearing technique limits internal heat buildup, keeps the cutting teeth cutting sharply, and ensures you can use the Snap-Lock system to instantly eject the remaining plug cleanly.
