The teeth are attached to a carbon steel body by a\nprocess called electron beam welding. The result is a tool composed of two\ntypes of metal welded edge-to-edge - also know as bi-metal construction.\nBecause the IRWIN Hole Saws are engineered and manufactured for exceptional\nsharpness and durability, they will cut much more than wood. These saws will\nalso cut holes in aluminum, copper, iron, stainless steel and zinc. The hole\nsaws also have a tooth \"pitch\" that varies from 4 to 6 teeth per inch. This\nreduces harmonics and improves performance. Also, the variation in depth of\ngullets between the blade's teeth provides more efficient chip clearance,\ngiving you greater cutting speed.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eBI-MTL 4-1\/2IN HOLESAW IRWIN\u003c\/li\u003e\n \u003cli\u003eBI-MTL 4-1\/2IN HOLESAW IRWIN\u003c\/li\u003e\n \u003cli\u003eBI-MTL 4-1\/2IN HOLESAW IRWIN\u003c\/li\u003e\n \u003cli\u003eBI-MTL 4-1\/2IN HOLESAW IRWIN\u003c\/li\u003e\n \u003cli\u003eBI-MTL 4-1\/2IN HOLESAW IRWIN\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-09-16T00:27:45+10:00","created_at":"2026-09-09T16:53:59+10:00","vendor":"IRWIN","type":"Hole Saws","tags":["industrial_Sep2026"],"price":22500,"price_min":22500,"price_max":22500,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":50652447736045,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B0002YQSMS","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Irwin Tools IRWIN Hole Saw, Bi-Metal, 4-1\/2-Inch (373412BX)","public_title":null,"options":["Default Title"],"price":22500,"weight":499,"compare_at_price":null,"inventory_management":"shopify","barcode":"024721001252","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/leoforward.com\/cdn\/shop\/files\/B0002YQSMS.jpg?v=1788936842","\/\/leoforward.com\/cdn\/shop\/files\/31bhHfC-kLL.jpg?v=1788936841","\/\/leoforward.com\/cdn\/shop\/files\/41s3aKCFlML_554be352-f373-4f6d-b040-638bd42fbb91.jpg?v=1788936841"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/files\/B0002YQSMS.jpg?v=1788936842","options":["Title"],"media":[{"alt":null,"id":41959832060141,"position":1,"preview_image":{"aspect_ratio":0.604,"height":500,"width":302,"src":"\/\/leoforward.com\/cdn\/shop\/files\/B0002YQSMS.jpg?v=1788936842"},"aspect_ratio":0.604,"height":500,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/B0002YQSMS.jpg?v=1788936842","width":302},{"alt":null,"id":41959832092909,"position":2,"preview_image":{"aspect_ratio":1.404,"height":356,"width":500,"src":"\/\/leoforward.com\/cdn\/shop\/files\/31bhHfC-kLL.jpg?v=1788936841"},"aspect_ratio":1.404,"height":356,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/31bhHfC-kLL.jpg?v=1788936841","width":500},{"alt":null,"id":41959832125677,"position":3,"preview_image":{"aspect_ratio":1.778,"height":360,"width":640,"src":"\/\/leoforward.com\/cdn\/shop\/files\/41s3aKCFlML_554be352-f373-4f6d-b040-638bd42fbb91.jpg?v=1788936841"},"aspect_ratio":1.778,"height":360,"media_type":"image","src":"\/\/leoforward.com\/cdn\/shop\/files\/41s3aKCFlML_554be352-f373-4f6d-b040-638bd42fbb91.jpg?v=1788936841","width":640}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eIrwin Tools IRWIN Hole Saw, Bi-Metal, 4-1\/2-Inch (373412BX)\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eIRWIN 373412BX BI-MTL 4-1\/2IN HOLESAW IRWIN From the\nManufacturer The IRWIN 373412BX 4-1\/2\" Bi-Metal Hole Saw is crafted from the\nhighest quality bi-metal.
