90°,2pcs,M2AI HSS,Industry Chamfering Chamfer Metal Countersink End Mill Deburring Drill Bit Tool Hole Screws Cutter (Ø30mm×10mmShank×71mmOAL 1Flute)

1.Widely used in hardness from aluminium,cast iron,brass,copper,magnesium alioy,plastics under HRC32(HRA66),or more processing soft materials.It is not suitable for materials that are too thick or too hard. 2.Full grinded cutter offer obtain accuracy and fine finish than other substrates. 3.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,air cooling. 7.Countersinks cut a cone-shaped opening to install screws and rivets flush with a surface or hold workpieces between centers on a lathe. They can also be used for chamfering and deburring. 8.The single flut:cutting edges can better chip evacuation,the cutting edges is not easy to blunt,does not vibrate at high speeds for faster cutting than multiple flutes.These countersinks are often used for cutting smaller holes. 9.Two, Three, or Four Flutes:fine finish face,Each additional flute increases the tool life by distributing the cutting load over more edges. However,fewer flutes provide better chip clearance when machining stringy materials such as plastic. 10.The countersink body diameter must be equal to or larger than the head diameter of the screw, center, or rivet being countersunk. Use a pilot hole that's larger than 10% of the countersink body diameter.
