Wokesi 4mm Cutting Dia,4mmShank Dia,75mmOAL,Extra Long,HRC45 4Flutes TiAlN Coated Solid Carbide Square End Mill Flat Endmill CNC Router Bits Cutting Tools for Slotting Milling(4mmDia×4mmShank×75mmOAL)

1.Widely used in hardness from copper,cast iron,aluminium alloys,titanium alloy,mold steels,stainless steels,alloys steels, tools steels to the high hardness of HRC45 or more processing materials. 2.Sharp cutting edges design and long shank for deep cavity machining. 3.Solid carbide tools offer long tool life and faster cutting speeds than other substrates,but more brittle.Make sure work piece and machine are stable,use hydraulic chucks,high quality collet chucks,or shrink fit chucks. 4.Please adjust the speed,feed and cutting depth according to actual cutting conditions. 5.Tool overhang,please use the required amount of minimum size,amount of long overhang is high vibration,turn it to lower the number of feed. 6.Adapt to several kinds of cooling conditions, for example oil mist,water,oil,air cooling.can be used for dry machining.
