With a 1-3\/4 inch saw diameter and a 1-5\/8 inch cutting depth, it handles a wide range of trade applications where precise hole sizing matters. The toothed cutting edge runs at a constant pitch of 5.5 teeth per inch, delivering consistent chip removal and controlled cutting action. Licensed tradespeople and skilled DIYers working in HVAC, plumbing, electrical, and general construction rely on this type of saw for conduit knockouts, pipe penetrations, and panel openings.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for residential and light commercial work wherever holes must be cut through metal panels, steel framing, wood studs, or similar materials. Its 1-3\/4 inch diameter makes it a common choice for standard conduit and pipe rough-in work. The high speed steel construction holds an edge under repeated use across mixed-material applications, reducing the need for frequent blade changes on multi-penetration jobs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-3\/4 inch saw diameter for standard conduit and pipe penetrations\u003c\/li\u003e\n\u003cli\u003e1-5\/8 inch cutting depth accommodates typical panel and stud thicknesses\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across metal, steel, and wood\u003c\/li\u003e\n\u003cli\u003eConstant pitch toothed edge at 5.5 TPI for consistent, clean cuts\u003c\/li\u003e\n\u003cli\u003eCompact profile — 1.8 inches wide by 1.8 inches long by 1.6 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement hole saw compatible with standard arbors accepting 1-3\/4 inch hole saw bodies.
