It features a 1-1\/2 inch saw diameter and a 1-9\/16 inch cutting depth, making it suitable for standard-depth penetrations through sheet metal, conduit knockout work, pipe notching, and similar tasks. The toothed cutting edge runs a variable pitch pattern, which reduces vibration and helps prevent tooth stripping on harder metals. The arbored design with a 1\/4 inch shank diameter provides a secure connection to a standard hole saw arbor or mandrel. Electricians, plumbers, HVAC technicians, and general contractors commonly use this saw for rough-in work and panel cutouts.\u003c\/p\u003e\u003cp\u003eThis hole saw fits into everyday trade workflows where a reliable, repeatable cut through metal is required. It is well suited for residential and light commercial installations, including electrical box knockouts, pipe penetrations through metal studs, and conduit entry points through metal enclosures. The 1-1\/2 inch diameter is a commonly called-for size in mechanical and electrical rough-in, and the 1-9\/16 inch cut depth accommodates typical wall and enclosure thicknesses encountered in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2 inch saw diameter for standard trade knockout and penetration work\u003c\/li\u003e\n\u003cli\u003e1-9\/16 inch cutting depth handles typical metal panel and stud thicknesses\u003c\/li\u003e\n\u003cli\u003eBi-metal construction provides durability when cutting through steel and other metals\u003c\/li\u003e\n\u003cli\u003eVariable pitch tooth pattern reduces vibration and extends tooth life\u003c\/li\u003e\n\u003cli\u003eArbored design with 1\/4 inch shank diameter for secure mandrel attachment\u003c\/li\u003e\n\u003cli\u003eToothed cutting edge delivers clean, consistent cuts in metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard hole saw arbors accepting a 1\/4 inch shank diameter.
