The teeth are attached to a carbon steel body by a process called electron beam welding. The result is a tool composed of two types of metal welded edge-to-edge - also know as bi-metal construction. Because the IRWIN Hole Saws are engineered and manufactured for exceptional sharpness and durability, they will cut much more than wood. These saws will also cut holes in aluminum, copper, iron, stainless steel and zinc. The hole saws also have a tooth \"pitch\" that varies from 4 to 6 teeth per inch. This reduces harmonics and improves performance. Also, the variation in depth of gullets between the blade's teeth provides more efficient chip clearance, giving you greater cutting speed\u003c\/span\u003e\u003c\/p\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e4\/6 Variable pitch teeth for reduced noise and improved performance\u003c\/li\u003e\n\u003cli\u003eBi-metal construction for toughness and long life\u003c\/li\u003e\n\u003cli\u003eVariable depth gullets provide more efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eElectron beam weld for stronger, longer lasting teeth\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHole Saw\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 4.700 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 5.500 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.300 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.224 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Bi-Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch:\u003c\/strong\u003e 4-6 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeld Type:\u003c\/strong\u003e Electron Beam Welded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":47737159975099,"sku":"DT373412BX","price":0.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/wiscocatalog.myshopify.com\/products\/dt373412bx-irwin-373412bx-hole-saw-4-12-in-bi-metal-electron-beam-welded-variable-pitch-teeth","provider":"Wisco Catalog","version":"1.0","type":"link"}
