Tungaloy Launches Small Diameter Indexable Shoulder Milling Cutter

Tungaloy has expanded its TungForce-Rec series of indexable square shoulder milling cutter. The series’ high insert density now includes 6 mm (.236″) diameter cutter bodies, which is said to be the smallest indexable shoulder mill available in the market, as well as size-04 inserts that are designed for axial cutting depths of up to 4 mm (.157″).

Featuring the V-bottom design of TungForce-Rec inserts in a compact form, the new size-04 inserts enable the cutter body to have a large core diameter and ample insert support, providing high tool rigidity and stability contrary to the small diameter.

The small size-04 inserts also enable TungForce-Rec04 to have a higher teeth density than conventional shoulder cutters of the same size, boasting two teeth for an 8 mm diameter cutter and three for a 10 mm. This reportedly enables TungForce-Rec04 to run higher feed speed than competitors when being fed at the same rate per tooth, enabling increased productivity.

The insert design provides the flank face with an obtuse clearance angle for enhanced cutting edge strength and sharpness. Two insert grades are available: AH3225 is the first choice for steel and AH120 is suited for cast iron. According to Tungaloy, both provide high reliability and long tool life for extremely high shoulder milling productivity. 16 new inserts and cutter bodies are introduced in this expansion.
