With a 3-1\/2 inch diameter and a 1-5\/8 inch cutting depth, it handles a wide range of trade applications where standard bi-metal saws fall short. The toothed cutting edge runs at a constant pitch for consistent chip removal. It is a non-arbored design, meaning the appropriate arbor must be sourced separately. HVAC installers, plumbers, and general contractors reach for this saw when working through dense substrates that would quickly wear down lesser tooling.\u003c\/p\u003e\n\u003cp\u003eThis hole saw is suited for trade work involving fiberglass panels, Formica laminate, masonry brick, MDF, plaster, and suspended flooring. Common applications include cutting penetrations for duct collars, pipe sleeves, electrical boxes, and drain rough-ins. The 3-1\/2 inch diameter is a standard size for many duct and pipe openings in both residential and light commercial installations. The 1-5\/8 inch cutting depth accommodates most wall, ceiling, and floor panel thicknesses encountered in typical service and new-construction work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting teeth for extended life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch saw diameter — standard size for duct collars, pipe sleeves, and electrical openings\u003c\/li\u003e\n  \u003cli\u003e1-5\/8 inch cutting depth handles standard panel and framing material thicknesses\u003c\/li\u003e\n  \u003cli\u003eConstant-pitch toothed edge promotes consistent cutting and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNon-arbored design allows use with a separately selected compatible arbor\u003c\/li\u003e\n  \u003cli\u003eRated for fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor applications.

Confirm the correct arbor is fitted and secured before operation. Wear appropriate eye and respiratory protection when cutting masonry, fiberglass, or MDF, as these materials produce fine particulate.
