Sandvik Coromant U-MAX Carbide Milling Insert, R215 Style, Rectangular, GC235 Grade, TiCN Coating, R2154415T308MWH,0.156" Thick, 0.032" Corner Radius (Pack of 10)

Used with the Sandvik Coromant U-Max 215.44 long edge milling insert holder for light or heavy machining on austenitic stainless steel and stainless steel castings in difficult-to-average machining conditions
GC235 grade is a chemical vapor deposition (CVD) coating of titanium carbon nitride (TiCN) and titanium nitride (TiN) over carbide that provides shock resistance without limiting wear resistance, offers toughness and good edge security, and performs well at low to moderate cutting speeds
Choice of light-machining (WL) or heavy-machining (WH) chipbreaker helps prevent chip buildup
Parallelogram shape provides two strong cutting edges
Long edge milling cutters offer a high metal removal capacity for edging and side milling applications
Maximum cut depth: 0.591 inches

The Sandvik Coromant R215.44 GC235 right-hand carbide indexable milling insert has a parallelogram shape, is available with a WL or WH chipbreaker, and provides shock resistance without limiting wear resistance for light machining of austenitic stainless steel and stainless steel castings in difficult-to-average machining conditions. GC235 grade is carbide and a thin coating of titanium carbon nitride (TiCN) and titanium nitride (TiN) applied through chemical vapor deposition (CVD). It offers toughness and good edge security, and performs well at low to moderate cutting speeds. In general, coatings extend insert life and provide better wear resistance than uncoated inserts.

This positive insert is used with the U-Max 215.44 long edge milling insert holder, a screw-style holding system for edging and side milling. It is available with a WL chipbreaker for light machining or a WH chipbreaker for heavy machining. It has an edge performance type M for highest edge security. The parallelogram shape provides two strong cutting edges. The insert has a hole in the center and an 11-degree clearance angle.

Milling inserts are coded according to their specific cutting and application capability (e.g., R215.44-090208M-WL). Each section of the code represents details of the insert: right or left hand, compatible toolholder series, size, thickness, corner radius, edge performance, and chipbreaker style. Tolerance of the inscribed width (iW) of the insert is + or - 0.002”. Insert thickness tolerance is + or - 0.001”. Insert shapes and sizes may have different cutting depths, speeds, lead angles, and feed rates. Generally, as the insert size and the iW become larger, the maximum cutting depth increases. Cutting depth influences the metal removal rate, the number of cuts, chip evacuation efficiency, and power required when using the insert. Indexable inserts are small cutting tools designed to remove material in external and internal cutting applications such as turning, milling, drilling, and grooving. They are held by an insert holder, have multiple cutting edges, and can be rotated when one edge wears down. Multiple inserts can accomplish a variety of cuts in one operation. An insert is either positive or negative, which refers to the rake or clearance angle at which the insert removes material.

Sandvik Coromant produces tools for turning, milling, and drilling. Headquartered in Sweden, the company manufactures tools used throughout the metalworking field, including the automotive and aerospace, die and mold, and general engineering industries.
