Advantages with the B-style Back Turning Inserts

  • Low radial forces
  • Gives better roundness
  • Keeps the desired size longer
  • Chip is curled before it hits the already finished shoulder
  • Gives good chip-control by curling the chip away from the surface
  • Positive cutting rake improves production and tool-life
  • Only a narrow parting off insert is required in order to clean up the non finished cylindrical diameter
  • The final diameter is produced only 1 mm from the side of the insert and tool holder, or away from the guide bushing, resulting in good stability even when small diameters are produced

Back Turning Insert Guide

Style B These back turning inserts are for general use in back turning applications in stainless steel, titanium, nimonic, hastaloy, high temperature alloys, alloyed steel and other hard and long chipped materials where good chip control is needed.
Style BC These back turning inserts are used when higher feed rate is wanted with cutting depths up to 1,5mm. Typical applications are shafts with long parts turned down to smaller diameters.
Style BP These back turning inserts are used when machining in sticky materials when there is a chance of an built up edge that can spoil the surface finish or reduce tool-life.
Style BT These back turning inserts have a corner treatment on the leading corner that improves the tool-life in harder materials. Try it when the wear on the B-style insert comes fast on this corner.
Style C These back turning inserts are used when there is an undercut required.
Style E These back turning inserts are used for fine turning, using high rev and low feed rate. This insert will give the best possible surface finish.
