Hello world.

Introducing GC4325 for steel turning.
A breakthrough in material science: the first grade featuring Inveio.

 

Featuring Inveio:

Performance beyond what the eye can see

An elaborate technology, designed by the smallest element. Inveio is the achievement of uni-directional crystal orientation: the true innovation that is redefining the world of metal cutting. It is here, where the atoms are more tightly packed towards the cutting edge that the greatest single effect on insert strength, wear resistance and tool life is achieved.
Simply Inveio.

Superior endurance

Securing maximum output

Combining high cutting data capability with a proven tool life increase is the key to GC4325. Put simply, GC4325 just keeps going and going, taking you on a direct route to machining excellence.

After rigorous testing, the results are clear. GC4325 has more to give when other inserts reach the end of their life.

Outstanding predictability

Have a stress free day (and night)

Insert wear will always happen but the key is being able to limit and control it. This is a true advantage of GC4325: a stronger edge line that lets you run your machines at night, or keep them going smoothly without stopping, all day long.

We guarantee the same reliable performance time after time.

Quality guaranteed,
reliability ensured.

Green light machining

Redefining ISO P25

One grade to cover what you do most

Steel is the most common material for many components, so a widely applicable grade will reduce tool inventory and related costs. Whatever type of steel you work with, be it bar materials to forgings or castings to pre-machined parts, in continuous or interrupted cuts from roughing to finishing; GC4325 has it all covered.

Innovation never sleeps

In 1969, the same year as the first moon landing Sandvik Coromant introduced the world’s first CVD-coated, cemented carbide insert - an ISO P25 grade. Since then we have continued to lead the way in tool material- and process development. GC4325 is the 7th generation of that grade and is once again a ground-breaking technological breakthrough: follow the twists and turns of its story here

Good for productivity, good for the environment

Balancing the need for technological advancement with the need for global sustainability is a difficult challenge, but GC4325 makes it that bit easier. Not only has GC4325 been improved in every performance area; new, high technology processes ensure that its carbide substrate contains a high proportion of recycled carbide material.

Just one more reason to choose GC4325 and Sandvik Coromant to meet your future challenges.

GC4325 opens the door to all of your machining goals and doubles your chances to excel in productivity.

Metal cutting efficiency

Time savers

  • Higher metal removal rates

The GC4325 advantage

  • Ability to increase cutting data
  • GC4325 has the ability to run at higher cutting data than other P25 grades
y) Metal cutting efficiency – chip volume/min x) Machine utilization - % Performance
y) Metal cutting efficiency – chip volume/min x) Machine utilization - % Performance

Machine utilization

Time killers

  • Insert change time
  • Production interruptions
  • Finding the right insert for each application

The GC4325 advantage

  • More pieces per edge
  • Fewer stops for insert change
  • Same tool life every time and no sudden breakage
  • Less rework and scrap
  • Broader coverage of application area in ISO P
