Seco Tools LLC expanded its Highfeed series of indexable-insert milling cutters with two new models, Highfeed 2 and 4, that present more teeth per diameter, thus allowing machine tool operators to achieve higher speeds and feeds for processing hard and tough workpiece materials.

Dubbed the world’s smallest high-feed milling cutter with indexable inserts, Highfeed 2 is prescribed for applications that require a high ramping angle or superior plunging performance. It features LP05 single-sided inserts with two cutting edges for cutter bodies that range from 0.5 to 0.75 in. diameter.

Available in three different geometries (ME, M and MD), these positive LP inserts easily handle sticky materials such as stainless steels, titanium and super alloys. Mounting types include Combimaster heads and cylindrical shanks.

Highfeed 4 cutters feature LO06 double-sided inserts with four cutting edges for cutter bodies that range from 1.00 to 2.50 in. diameter. Available in four different insert geometries (ME, M, MD and D), these close-pitch and negative-pocket LP inserts cost effectively machine common workpiece materials. Mounting types include Combimaster heads, cylindrical shanks and shell ends.

Seco designed both the Highfeed 2 and 4 cutters to reduce vibrations for smooth, stable cutting and increased productivity. The cutters also efficiently evacuate chips, for “worry-free” operation. Furthermore, Highfeed 2 and 4 cutters truly excel when processing challenging materials at high speeds on smaller machines with high-speed, low-torque spindles.

According to Seco, its Highfeed series of milling cutters, in general, permit up to three times faster machining than conventional methods. They provide shallow depths of cut with high feed per tooth rates to deliver greater metal removal rates for an overall boost in productivity.
