Tungaloy Corp. introduces TungTri-Shred, a new shoulder milling cutter for highly productive machining. With today's dramatic growth in the performance of machine tools, high-speed machining is often the first choice for manufacturers.

Tungaloy Corp. offers TungForce-Rec, the indexable miniature shoulder milling cutter. The TungForce-Rec insert has a unique V-shaped bottom to enhance the insert's resistance to centrifugal force, assuring reliability and high productivity during high-speed machining, according to the company.

Tungaloy Corp. offers MillQuadFeed, a new high-feed milling cutter. With a depth of cut up to 0.098" (2.5mm) and a feed rate up to 0.078" (2.0mm) per tooth, MillQuadFeed accomplishes astounding metal-removal rates in rough milling operation, according to the company.

DoTriple-Mill is Tungaloy's latest facemilling cutter, featuring an innovative dovetail clamping system that will reportedly dramatically reduce insert lift up and excessive shear force imposed on the screws during heavy-duty milling. Compared with the last generation of facemilling platforms, DoTriple-Mill delivers stable machining and consistent tool life.
