The Seco Double Quattromill 14 is available in 45° and 68° lead angle versions for depths of cut up to 6 mm (0.236 in) and 8 mm (0.315 in), respectively. The 45° angle, which excels in weak or unstable fixturing, provides better chip thinning and higher feed rates. The 68° angle reaches high depths of cut with the same size inscribed circle (I.C.) on the insert as the 45° angle, but with better clearance to avoid sidewalls or part fixturing. Unlike the inserts on standard tangential-type face mills, the Double Quattromill 14 offers free cutting to lower cutting forces and machine power consumption while it extends tool life.

Double Quattromill 14 cutter bodies come in fixed-pocket and cassette styles, with standard or close pitch along with metric or inch versions. Seco also applied its new surface texture technology to the Double Quattromill 14’s cutter body flute surfaces for enhanced chip control and evacuation as well as durability.

The Double Quattromill 14 offers three insert ranges with various edges and grade options. The ME10 geometry works with sticky materials such as titanium and stainless steel. The M10 geometry includes sharper edges and smaller T lands for reduced cutting force that excels at lower horsepower levels, working with sticky materials, some tool steels and superalloys. The M16 provides the best edge protection of the three insert geometries when machining abrasive materials such as steels, tool steels and cast irons.
