Tangential Geometry for Fast Metal Removal

Iscar is introducing a new family of tools for high production milling. The new MINITANG inserts from Iscar applies the tangentially clamped design of the larger TANGMILL tool to the smaller MINITANG inserts. These inserts feature four helical 0.315" long cutting edges. Due to the small size of the T490 LNMX 0804 PN-R inserts and their tangential orientation in the pocket, these tools have a larger core diameter design than regular radially oriented inserts. This combination of features produces Fast Metal Removal results on a variety of milling applications.

The T490 E90LN endmills can be used for machining 90° shoulders at high feed rates with no mismatch. Due to the helical cutting edge and positive rake angle, these inserts feature a soft and clean cut. In addition, the design of the new MINITANG tools makes it possible to use them on side plunging applications as well.

Currently the new T490 E90LN family of endmills is available in a variety of sizes. The smallest tool diameter available is 0.625", and the largest is 1.50". These are available with either coarse or fine pitch configuration for each diameter.
