The number of flutes varies; fewer flutes provide better chip-carrying capacity, while more flutes produce a finer finish. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering greater resistance to heat and abrasion. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials.\nThe 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The tool’s square end has straight cutting edges that create sharp, unrounded cuts, while the center-cutting design has cutting teeth at the end of the tool that support making pocket cuts, profiling, and slotting. Cutting diameter tolerance is +0.001” to -0.000”. The end mill has a Weldon shank.\nEnd mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flu\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Augusta Warehouse","offers":[{"title":"Default Title","offer_id":50852952473657,"sku":"AW-B00075G0XE","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0833\/2846\/7001\/files\/61nYWdmWunL.jpg?v=1792418329","url":"https:\/\/augustawarehouse.com\/products\/niagara-cutter-n52121-cobalt-steel-square-nose-end-mill-inch-weldon-shank-uncoated-bright-finish-finishing-cut-30-degree-helix-4-flutes-0-375-cutting-diameter-0-375-shank-diameter","provider":"Augusta Warehouse","version":"1.0","type":"link"}
