Built around a 3.5 TPI tooth geometry, this hole saw is engineered for extended tooth life in metal applications. A thermoset coating reduces friction at the cut, allowing faster material removal and optimized performance with cordless tool platforms. Licensed electricians, plumbers, HVAC installers, and general contractors use this saw for drilling clean, accurately sized holes through a wide range of substrates.\u003c\/p\u003e\u003cp\u003eThis hole saw fits residential and commercial installation work where repeatable, clean-bore holes are required. The 3.5 TPI design handles sheet metal, conduit knockout work, pipe rough-in, and structural lumber drilling. All-access slots along the body allow plug removal without stopping to use a separate tool, reducing downtime between consecutive holes. An open slot design also improves pilot bit visibility for accurate placement and promotes chip ejection to keep the cut cool during extended use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5 TPI bi-metal tooth design engineered for extended life in metal cutting applications\u003c\/li\u003e\n\u003cli\u003eThermoset coating reduces friction and delivers up to 25 percent more holes per battery charge on cordless tools\u003c\/li\u003e\n\u003cli\u003eAll-access slots allow fast plug removal and improved pilot bit visibility for accurate hole placement\u003c\/li\u003e\n\u003cli\u003eOpen slot geometry promotes chip ejection to reduce heat buildup during use\u003c\/li\u003e\n\u003cli\u003eLifetime Tooth Break Warranty covering tooth breakage under normal use conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with arbors TV 138-923 and TV 139-793.

Ensure the pilot bit is fully seated and the arbor is properly torqued before beginning a cut. Always de-energize circuits and relieve system pressure before drilling into panels, pipe chases, or pressurized assemblies. Use appropriate PPE including eye protection and gloves when cutting metal or composite materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 2-1\/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\u003eWeight\u003c\/strong\u003e: 9.94 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Milwaukee Electric Tool Corp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-56-0132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51524622876978,"sku":"49-56-0132","price":305.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7a2817b9ca6e01bd9a4cfff776fa7d3.jpg?v=1785453281","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-56-0132-bi-metal-hole-saw-2-1-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
