New technology for indexable drilling

December 20. 2013

MVX drills offer high rigidity with 2, 3, 4, 5 and 6 times L/D availability.

Technical Information:
  • Economical insert with 4 cutting edges
  • Unique insert design includes a wavy design chip breaker which provides excellent chip control.
  • Insert design also includes a wiper type geometry; this will help achieve excellent wall accuracy.
  • CVD grades MC1020 and MC5020 are recommended for the periphery position for higher speeds and wear resistance.
  • PVD grade VP15TF is recommended for the center position suitable for lower speeds while providing fracture resistance.
  • The above recommended insert positions control deformation and vibration; also enabling maximum drill depth of 6xs' L/D.
  • Drill body has increased surface hardness providing high rigidit.y, resistance of deformation and abrasion.
  • Extra body thickness behind inner edge helps resist principal forces preventing twisting and deformation.
  • Inclined through coolant holes improve chip evacuation and maintain coolant pressure.

Applications to Target:
  • Drilling in mild, carbon and alloy steels, austenitic stainless steels, ductile and cast irons.
  • Drilling of open and blind holes along with angled or radial surfaces.
  • Unconventional internal and external turning applications
  • Flat bottom drilling
