Unique system for wide grooving and wide profile grooving

TungHeavyGroove efficiently reduces machining time on wide-width grooving and forming of complex profiles

Applications & Features

External groovingProfilingCoolant hole

1. Easy insert clamp operated from front face

Indexing can be operated from front face of toolholder, reducing insert changing time and machine downtime.

2. Highly rigid lever-clamping provides stable grooving

Dovetail structure prevents insert movement during wide grooving operations.

3. Profile grooving inserts and tools

  • Inserts are supplied in width (W) 10 – 25 mm.
  • The insert length is extended for profile shapes up to 5.5 mm depth.
