The latest addition to Tungaloy’s TungMeister changeable-head end mill system is a line of modular heads for TungForce-Rec, the indexable miniature shoulder-milling cutter series.

TungForce-Rec features a V-shaped insert, designed to avoid movement under high centrifugal force while delivering reliability, even when used at a high metal removal rate. The insert’s large rake angle ensures light cutting action, while the obtuse angle of the insert’s flank face strengthens the cutting edge and helps prevent chipping. The pockets in the body design are said to be more compact and sturdy than other cutters with flat-bottom inserts, enabling the small tool diameter to retain a large core diameter. The miniature shoulder mills are suited for applications including shouldering, slotting and 3D profiling.

The inserts feature a 6-mm (0.24") maximum depth of cut and are available in three different grades (AH3135, AH120 and KS05F) for a range of materials. Tool diameters are available from 8 to 16 mm (0.32" to 0.63").

TungMeister’s lineup of TungForce-Rec modules feature secure coupling with minimal bending at the flange and tapered shank contacts. Available standard shank materials include cemented carbide, steel and vibration-damping pure tungsten.
