About Sandvik Coromant COROMILL Carbide Milling
The Sandvik Coromant R245 GC1030 right-hand carbide indexable milling insert has a square shape, is available with a PL chipbreaker, ML chipbreaker, PM chipbreaker, or wiper flat, and provides a balance of resistance to shock and wear in light or medium machining and mirror finishing of steel in average machining conditions where the tool may be unstable. A combination of carbide and a thin coating of titanium aluminum nitride (TiAlN) and titanium nitride (TiN) applied through physical vapor deposition (PVD) performs well when a tool is unstable, such as in short engagements, long overhangs, and when there is a risk of chip jamming. In general, coatings extend insert life and provide better wear resistance than uncoated inserts. Inserts with PVD coatings maintain a sharper cutting edge than those with chemical vapor deposition (CVD) coatings. This positive insert is used with the CoroMill 245, a screw-style insert holding system for use in face milling and mirror-finishing applications. The insert has a square shape that provides strong cutting edges. The chipbreakers available with this insert provide a range of edge performances. The light-machining ML and PL chipbreakers are available with an E edge performance type for highest sharpness and precision. The ML chipbreaker has a sharper, less rounded cutting edge and the PL chipbreaker has a stronger, more rounded cutting edge. The PL chipbreaker is also available with an M edge performance type for highest security. The medium-machining PM chipbreaker is available with an M edge performance type. The mirror-finishing wiper flat (W) is available with an E edge performance type. Wiper flat inserts interspersed with chipbreaker inserts throughout a facemill improve the finish on a workpiece. The insert has a hole in the center and a 29-degree clearance angle. The ML, PL, or PM chipbreaker insert has four cutting edges; the wiper flat insert has one cutting edge.
