Tungaloy's DoFeedTri high-feed milling cutter includes six total cutting edges

Tungaloy has introduced DoFeedTri high-feed milling cutters that use double-sided inserts with six total cutting edges.

The inserts come in a trigonal shape with a greater contact face that achieves secure insert retention when screw-clamped on the cutter, eliminating insert movement during machining, according to the company.

Ramping down, the cutter first bottom-cuts the surface with the leading insert, then further cuts the same surface with its trailing insert. A reduced entry angle of the cutter eliminates chatter, improving stability during machining with long overhang tool setup.

Two insert grades are available: AH3225, the first choice for steel promising exceptionally long tool life and AH8015 that demonstrates superior performance in hardened steel and heat-resistant superalloys. Cutters are offered in the diameter range from 16 to 50 mm in metric sizes and from 5/8 to 2 in. in imperial sizes. A total of 26 new cutters and inserts have been introduced.
