Integral PCBN Standard Inserts
Integral PCBN (Polycrystalline Cubic Boron Nitride) standard inserts are one-piece solid PCBN cutting tools—the entire insert is made from PCBN rather than having only a brazed PCBN tip. This monolithic design delivers maximum hardness and thermal stability for continuous or interrupted machining of hardened steels, chilled cast iron, powder metals, and other wear-resistant alloys. Because there is no carbide substrate, the insert offers uniform PCBN properties throughout, making it ideal for aggressive cutting conditions, long production runs, and tight tolerance finishing.

Frequently Asked Questions
- What makes integral PCBN different from tipped PCBN
inserts?
Integral inserts are solid PCBN throughout, while tipped inserts have only a brazed PCBN layer on a carbide base. - Which materials are best for integral PCBN inserts?
Hardened steels, chilled/grey cast iron, sintered powder metals, and hard superalloys. - Do they fit standard tool holders?
Yes, they are manufactured to ISO/ANSI standards and fit conventional holders. - Are they suitable for interrupted cuts?
Yes. The full-PCBN body provides excellent edge strength for intermittent operations. - Can I run them dry?
Absolutely. Dry machining is preferred to avoid coolant-related thermal shock. - How does tool life compare to carbide or tipped PCBN?
Typically 4–6× longer than carbide and 1.5–2× longer than tipped PCBN in hard-steel finishing. - What surface finish can I expect?
Finishes as fine as Ra 0.2 µm, depending on feed and speed settings. - Is regrinding possible?
Minor edge honing is feasible, but major regrinding is limited; inserts are indexable. - What cutting parameters are recommended?
Speeds of 150–350 m/min and feeds of 0.05–0.25 mm/rev, depending on hardness and operation.
10.Do integral PCBN inserts require special
coatings?
No coating is needed; the PCBN itself provides extreme wear and heat
resistance.
