The precision-ground, trigonal insert boasts a large core cross-section and maximum cutting length. The design of the cutting edges produces a positive cutting geometry despite the negative insert angle. The six cutting edges on each indexable insert provide excellent value for money for each edge.

The DA62 system can also be used for roughing and finishing. During trials, the milling system resulted in excellent surface finishes. Selecting the axial and radial angles has enabled a lower torsional moment and lower transverse loading of the spindle to be achieved compared with previous systems. This allows the DA62 to be used on less powerful machines. A further advantage of the selected axial angle is its excellent ability to remove chips, particularly in the case of helical plunge milling.

The cutting edge shape generates a precise 90° corner angle with a maximum cutting depth of 4.5 mm (0.177"). The inserts are currently available with corner radii of 0.4 mm and 0.8 mm (0.015" and 0.031"). They use the tough, tried-and-tested carbide substrate SA4B, which is a useful all-rounder for milling steel, stainless steel, cast iron and aluminium. The inserts are also available in SD6A, which is especially well suited to machining cast iron. Both carbide grades are held in stock.

The milling bodies are available in diameters of 20, 25 and 32 mm (0.787", 0.984" and 1.259"), with a Weldon toolholder (DIN 1835 B) or as a screw-in milling cutter. In these variants, the milling tools are equipped with two, three and four inserts. The tools are available as arbour milling cutters (DIN 8030 A) with cutting edges of 40, 50, 63 and 80 mm (1.574", 1.968", 2.480" and 3.149"), equipped with five, six, eight or ten inserts. All bodies have internal cooling directed at the point of cutting.

The DA62 milling system ensures process reliability for a broad range of applications, maximum performance and economic benefit for the customer.
