The performance boost in the cutting area!

Freeform chip breakers for small part manufacturing and micro cutting

Lack of chip breaking and insufficient chip removal are major challenges during metal-cutting machining. The focus is also on high productivity, process reliability and the longest possible tool life.

Perfect chip control is therefore a central issue in all modern production. These requirements are often difficult to fulfil with ground chip breakers.

New manufacturing technologies which are ideally suitable for generating any three-dimensional shapes have increased the degree of design freedom tremendously in comparison to grinding technology. The new G-LINE at multidec® has highlighted the use of this new freeform design technology. Well thought-out chip breaking geometries, fitted to the well-tried inserts of the multidec®-CUT 1600 and -CUT 3000 series, provide maximum performance.

Freeform-modelled chip breakers achieve significant improvements in a wide range of materials in comparison to ground ones. This advantage is particularly evident with materials which are difficult to machine such as super-alloys.

As well as significantly improved chip control, cutting values that are up to 30 % higher and a tool life that is up to 50 % longer can be achieved using the G-LINE inserts in comparison to ground chip breakers.


  • improved chip control

  • better cutting values

  • longer tool life

  • smaller chip volume

  • better process reliability

  • wear-resistant and tough carbide substrate with two heavy-duty coatings

  • sharp and rounded cutting edges

  • can be used on all multidec®-CUT 1600 and multidec®-CUT 3000 holders


Success story

Operation grooving and turning with the “GC20” chip breakerIn a comparison between the new G-LINE “GC20” chip breaker and a ground chip breaker which has been established for a long time, perfect rolled chips and an extremely neat finish were achieved on the workpiece with consistent cutting data. The tool life was increased by 200 %, from 3000 to 9000 parts.
