About Wokesi Pack Of 3Pcs,4 6 8mm Cutting Diameter,Ball

3Pcs Ball Nose Endmills Size: A.R2 Cutter:Blade Diameter=4mm,Flute Length=25mm,Shank Diameter=4mm,Overall Length=75mm. B.R3 Cutter:Blade Diameter=6mm, Flute Length=30mm,Shank Diameter=6mm,Overall Length=75mm. C.R4 Cutter:Blade Diameter=8mm, Flute Length=40mm,Shank Diameter=8mm,Overall Length=100mm. 1.Widely used in hardness from copper,cast iron,aluminium alloys,titanium alloy,mold steels,alloys steels, tools steels to the high hardness of HRC45 or more processing materials. 2.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. 3.Please adjust the speed,feed and cutting depth according to actual cutting conditions. 4.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. 5.Adapt to several kinds of cooling conditions, for example oil mist,water,oil,air cooling.can be used for dry machining.
