Mitsubishi Materials Corporation has launched new smaller diameters, φ14 mm to φ16.5 mm sizes for the MVX indexable drill series.
The existing MVX drill provides excellent economy due to the 4-corner insert design and achieves a high cutting performance as well as long tool life. This is due to the optimum positioning of the outer and inner inserts on the drill body. To complement the existing sizes, the range has been expanded to include smaller sizes, φ14 mm to φ16.5 mm.
Features of the MVX drill
1. Optimum positioning of the outer insert and inner insert; A CVD coated grade with high wear resistance for the outer insert due to the higher cutting speeds and a PVD coated grade with high stability for the inner insert due to the lower cutting speeds, thereby achieving optimum balance and long tool life.
2. Increased surface hardness of the tool body prevents abrasive damage caused by chip flow. Therefore, longer tool life of the body is achieved.
3. Chip evacuation when drilling deep holes is improved with specially designed through coolant holes that maintain coolant pressure.
