Built to a 1-1\/8-inch cutting diameter, this hole saw features a 3.5 TPI tooth geometry engineered to extend tooth life in demanding metal applications. A thermoset coating reduces friction during the cut, which is especially effective when running cordless tools — the coating is optimized to deliver more holes per battery charge compared to standard uncoated saws. Electricians, plumbers, and HVAC technicians will find this saw appropriate for everyday rough-in and panel work where accurate, repeatable hole sizing is required.\u003c\/p\u003e\u003cp\u003eThis hole saw is suited for residential and light commercial applications where a 1-1\/8-inch opening is needed in sheet metal, steel enclosures, wood framing, or drywall assemblies. The all-access slots on the body allow for faster plug removal between holes, reducing downtime on the job. The slot design also provides improved pilot-bit visibility for accurate placement on a layout mark, and aids chip ejection to keep the cutting zone cooler during extended use. Compatible arbors include TV 138-921 and TV 145-615.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/8-inch cutting diameter for standard trade rough-in applications\u003c\/li\u003e\n\u003cli\u003e3.5 TPI bi-metal tooth design engineered for extended life in metal cutting\u003c\/li\u003e\n\u003cli\u003eThermoset coating optimized for cordless tool use, improving cuts per charge\u003c\/li\u003e\n\u003cli\u003eAll-access slots allow fast plug removal and improved pilot-bit visibility\u003c\/li\u003e\n\u003cli\u003eSlot geometry promotes chip ejection to reduce heat buildup during the cut\u003c\/li\u003e\n\u003cli\u003eLifetime Tooth Break Warranty per manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with arbors TV 138-921 and TV 145-615.

Secure the workpiece before drilling and ensure the pilot bit is properly seated before beginning the cut. Always wear appropriate eye protection and gloves when cutting metal. Follow applicable NEC or IPC requirements when sizing penetrations through structural or rated assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-1\/8 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\u003eWeight\u003c\/strong\u003e: 4.5 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-56-0052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51524899406130,"sku":"49-56-0052","price":200.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78eacfc56a9124d0b6e81b01cccf9119.jpg?v=1785461078","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-56-0052-bi-metal-hole-saw-1-1-8-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
