The bi-metal construction combines a hardened high-speed steel tooth band with a flexible alloy steel body, delivering durability under repeated use. Rated at 115 RPM, it is suited for controlled-speed drilling through wood, aluminum, copper, iron, stainless steel, and zinc. Electricians, plumbers, and HVAC technicians reach for this saw when cutting clean, accurate holes in both structural and mechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis hole saw fits typical trade install scenarios where multi-material cutting is required in a single job — running conduit through framing, cutting pipe penetrations, or sizing knockouts in sheet metal enclosures. Its 3-inch diameter is a common size for pipe and conduit rough-in work in residential and light commercial construction. The bi-metal design reduces the need to switch between saws when moving from wood substrate to metal backing on the same penetration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBi-metal construction with high-speed steel teeth for extended tooth life across hard and soft materials\u003c\/li\u003e\n  \u003cli\u003e3-inch cutting diameter suits common conduit, pipe, and knockout applications\u003c\/li\u003e\n  \u003cli\u003eCuts wood, aluminum, copper, iron, stainless steel, and zinc in a single tool\u003c\/li\u003e\n  \u003cli\u003e115 RPM operating speed rating supports controlled cutting to reduce heat buildup\u003c\/li\u003e\n  \u003cli\u003eSold individually — each unit is one hole saw\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard arbor-style hole saw mandrels compatible with 3-inch bi-metal hole saws.

Secure the arbor firmly before use and confirm the workpiece is clamped or otherwise restrained to prevent rotation during cutting. Use cutting fluid or wax when working through ferrous metals to reduce heat and extend tooth life. Wear appropriate PPE including eye protection when operating any hole saw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 115 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Material\u003c\/strong\u003e: Bi-metal (high-speed steel teeth)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Wood, aluminum, copper, iron, stainless steel, zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: IRWIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 373300BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51347897319730,"sku":"373300BX","price":68.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499625.jpg?v=1782115742","url":"https:\/\/voomisupply.com\/products\/irwin-373300bx-bi-metal-hole-saw-3-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
