If the runout accuracy exceeds 0.01mm, correct it before cutting.  \u003cbr\u003e\nKeep the tool extension from the collet as short as possible. If a longer extension is necessary, reduce the speed, feed rate, or cutting volume.  \u003cbr\u003e\nIf abnormal vibrations or noises occur during cutting, reduce the speed and feed rate until the situation improves.  \u003cbr\u003e\nFor cooling, mist or air spray methods are recommended to enhance milling effectiveness.","brand":"Dr.Cutter","offers":[{"title":"Default Title","offer_id":48690671157476,"sku":"BD550GPR-2Sd12L55-D12L150","price":136.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/0988\/4132\/files\/e6b0d34ead9b67757eb0837f3ec0fc89.jpg?v=1775704643","url":"https:\/\/www.dr-cutter.com\/products\/hrc55-carbide-square-end-mills-2-flute-tisin-coated-for-milling-alloy-steels-hardened-steel-metal-etc-d12-150mm","provider":"Dr.Cutter","version":"1.0","type":"link"}
