Original Press Release:


Long Edge Milling Cutter Doubles Throughput Of Slotting, Edging, And Shoulder Milling


Sandvik Coromant's new CoroMill® 390 long edge indexable milling cutter doubles productivity in slotting, edging and deep pocket milling operations. The latest additions to the CoroMill 390 family of milling cutters also improve chip removal and reduce horsepower requirements. Contouring steel castings, for instance, the quiet, stable cutter achieved 804 sfm, twice the speed of comparable cutters, yet drew just 45% of the machine power. The versatile cutters are available with 11 mm and 18 mm inserts for light to heavy machining of materials ranging from aluminum to hardened steels.

The CoroMill 390's cutter body is machined from pre-hardened steels and features high precision insert pockets for accurate 90° edge positioning with minimal runout and mismatch. The helical arrangement and refined cutting edge of the inserts minimize vibration while the efficient flute design maximizes chip evacuation. When used with the strong, stable Coromant Capto modular toolholding system, the 390 long edge cutter provides free, smooth cutting with optimum access to deep cuts.

The 11 mm insert cutter is 1.25 to 2 in. diameter, 1.42 in. to 3.9 in. length of cut and ideal for light cutting and lower horsepower machines. Designed for heavy machining, the 18 mm version comes 1.69 in. to 3.9 in. diameter, 1.5 to 8 in. length of cut. Sandvik custom-engineered Tailor Made versions are also available to meet specific milling requirements.
