Mitsubishi Materials Indexable drill MVX

[Combination insert of outer blade CVD & inner blade PVD]
By placing a highly wear-resistant CVD-coated carbide grade on the outer blade, which has a high cutting speed, and a highly stable PVD-coated carbide grade, on the inner blade, which has a low cutting speed,
Optimize wear balance and achieve long life.
[Highly rigid body]
The surface hardness has been increased compared to conventional products, and the abrasion resistance against chips has been strengthened, resulting in a long service life.
Optimal insert placement suppresses holder deformation and chatter. This makes it possible to drill holes with a maximum of L/D=6.
[Optimal groove cutting position to suppress holder deformation]
By providing a wall in the direction of the main cutting force of the inner blade at the cutting position of the groove, deformation of the holder is suppressed when the insert bites.
[Adoption of slanted coolant hole]
By adopting an inclined coolant hole with relatively little loss of coolant momentum, it supports chip evacuation from deep holes.
Drilling of steel, stainless steel, cast iron, nonferrous metals, and high hardness steel
*When using VP15TF for the outer cutter, lower the cutting speed vc to around 70%.
*For external lubrication, the maximum machining depth should be L/D=3. Other machining depths are not recommended.
*When machining stainless steel, be sure to use internal lubrication.
