With a 3-3\/8 inch saw diameter and a 1-5\/8 inch cutting depth, this saw handles full-depth cuts through thick substrates including fiberglass, masonry brick, MDF, plaster, Formica, and suspended flooring. The toothed cutting edge with a constant pitch pattern delivers consistent chip clearance and reduces vibration during the cut. It is used by HVAC technicians, electricians, plumbers, and general contractors who routinely work with abrasive or composite materials.\u003c\/p\u003e\n\u003cp\u003eThis hole saw is well-suited for trade applications involving penetrations through fiberglass duct board, plaster walls, masonry brick, MDF panels, and Formica surfaces. The 3-3\/8 inch diameter makes it a practical choice for cutting openings sized for standard pipe, conduit, or duct fittings. The carbide-tipped construction is particularly valued in situations where a single cut through an abrasive substrate would destroy a standard steel blade. Licensed trades across HVAC, plumbing, and electrical regularly use this size for rough-in and finish penetration work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edge resists wear on abrasive materials including masonry brick and fiberglass\u003c\/li\u003e\n  \u003cli\u003e3-3\/8 inch saw diameter suits standard pipe, conduit, and fitting penetration sizes\u003c\/li\u003e\n  \u003cli\u003e1-5\/8 inch cutting depth handles thick panels, walls, and flooring substrates in a single pass\u003c\/li\u003e\n  \u003cli\u003eConstant pitch tooth pattern provides smooth, consistent chip clearance throughout the cut\u003c\/li\u003e\n  \u003cli\u003eRated for fiberglass, Formica, masonry brick, MDF, plaster, and suspended floor applications\u003c\/li\u003e\n  \u003cli\u003eNon-arbored design allows use with compatible arbor\/mandrel systems selected by the installer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with separately sourced arbors and mandrels compatible with standard hole saw shanks.

Secure the workpiece before drilling and use appropriate RPM settings for the material being cut, as abrasive substrates like masonry and fiberglass generate significant heat. Wear eye and respiratory protection when cutting MDF, fiberglass, or plaster, as these materials produce fine particulate. Follow applicable OSHA and local safety codes for rotary cutting tools on job sites.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Diameter\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Depth\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSaw Material\u003c\/strong\u003e: Carbide Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Constant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Fiberglass, Formica, Masonry Brick, MDF, Plaster, Suspended Floor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 65633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51693271122226,"sku":"65633","price":77.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9d2dbb73dad7c791b1132e18d589efd.jpg?v=1788309972","url":"https:\/\/voomisupply.com\/products\/starrett-65633-hole-saw-3-3-8-in-carbide-tipped","provider":"Voomi Supply","version":"1.0","type":"link"}
