Each end mill is inspected under high magnification to ensure that it meets our stringent standards. 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.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,when the tool overhang length is longer,please adjust the speed.feed and cutting depth. 4. Adapt to several kinds of cooling conditions, for example oil mist,water,oil,air cooling.can be used for dry machining. 5.The design of a two flute ball end mill allows for plenty of chip evacuation making them most effective in contouring deep pockets in molds and dies. Four or more fluted ball nose end mills have less chip evacuation due to their design but with multiple cutting edges they can produce very smooth finish by running lighter chip loads, without sacrificing a high rate of production.
