SUMIBORON Grooving Tools for Hardened Steel

GWB

  • Characteristics
  • Improved tool rigidity by adopting a vertical-use insert
  • The holder uses a newly developed double clamp and has improved stabiity through its continuous/interrupted cut. It can also do traverse machining.
  • By utilizing coated SUMIBORON BNC30G that is grooving machining grade, you get a long tool life through its interrupted cut. (We recommend BN2000 for continuous machining.)
  • It can handle grooving machining of various hardened steel with an abundance of edge widths from 1.5mm-6.0mm.
