The new M2131 Sky·tec Ramping Cutter from Walter reportedly brings new, higher levels of process reliability to the machining of nonferrous metals such as the aluminum wrought alloys or aluminum lithium alloys often used in aircraft structural components. The cutter allows shorter machining time due to its high metal-removal rate and delivers long tool life thanks to the low build-up on the cutting edge.

The new M2131 boasts protection against centrifugal force at the insert contact surface, which helps ensure the tool's high level of process reliability even at maximum speeds, and its V-shaped cutting edge for ramping promotes rough milling and semi-finishing of pockets with high chip volume.

This 90° shoulder milling cutter with ramping capability has a maximum cutting depth of 0.59 in. or 0.78 in. (15 or 20 mm), a diameter range of 0.98 in. to 3.14 in. (25 to 80 mm), and a high level of radial runout accuracy. The M2131, with integral cooling for MQL or emulsion, has a finely balanced basic body, with different interfaces such as HSK, ScrewFit, cylindrical shank or shell mill mount. It has two sizes of indexable inserts with various corner radii, and employs the new milling grade WNN15, known for its extremely long tool life.
