Start with your machining goal.
CY grades provide a starting point for cast iron and hardened steel enquiries. The exact grade–model combination requires confirmation.
General machining
A starting point for general machining of hardened steels and cast irons. Include interruption level and machine stability in the review.
High-speed fine finishing
For high-speed fine finishing enquiries in hardened steels and cast irons. Confirm setup, parameters and edge preparation before trials.
A suitable insert starts with the application.
Cast iron turning
Identify gray, ductile or alloy cast iron, together with hardness, allowance and interrupted surfaces.
Hardened steel turning
Provide steel designation, hardness and dimensional tolerance. Compare the ceramic and CBN options where appropriate.
Edge & holder compatibility
Provide the holder code, current insert and edge requirements. Match seat, clamp and specification before ordering.
Questions about CNGA ceramic inserts
Will this insert fit my existing holder?
Confirm the full insert and holder codes, seat geometry, thickness and clamping arrangement. A CNGA family name alone does not establish compatibility.
Which grade should I select?
Start with your material, hardness and operation. Include interruption level, speed, feed, depth of cut and finish requirements. If uncertain, choose “Recommend a grade” in your enquiry.
Are all listed models in stock?
The specification table is a reference range. Send your model, grade and quantity for supply and lead-time confirmation.
Can I use CNGA ceramic inserts for interrupted cutting?
This depends on the grade, edge preparation, workpiece and rigidity. Send details of the interrupted surfaces before deciding.
Can you review a custom specification?
Send a drawing or sample details with your machining requirements for a feasibility review.
