The saw runs a 3.5 TPI tooth geometry engineered to extend tooth life in metal applications. A thermoset coating reduces heat buildup during the cut, which is especially useful when running cordless tools where battery efficiency matters. ALL-ACCESS SLOTS are machined into the body to allow faster plug removal, reducing downtime between cuts on production jobs. This is a hand tool accessory installed by electricians, plumbers, HVAC technicians, and general contractors.\u003c\/p\u003e\n\u003cp\u003eThis hole saw is suited for residential and light commercial applications where 3-1\/4-inch bored penetrations are required — conduit knockouts, pipe pass-throughs, HVAC duct penetrations, and structural framing rough-ins. The thermoset coating is optimized to deliver extended run time when paired with cordless platforms, making it a practical choice for field work where a compressor or corded tool is not available.

Secure the workpiece before drilling and ensure the arbor and pilot bit are properly seated and locked before operation. Keep cutting speeds appropriate for the material being cut to avoid premature tooth wear or overheating. Disconnect power from the drill or driver before changing the hole saw or removing a plug.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Design\u003c\/strong\u003e: 3.5 TPI bi-metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Thermoset\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 045242193370\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: MILWAUKEE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-56-0183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51383035822386,"sku":"49-56-0183","price":36.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671138.png?v=1782586257","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-56-0183-bi-metal-hole-saw-3-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
