Ceramic / Cermets / Silicon Nitride

Black & White Ceramics

Part No.	Description
NS410	Our WHITE ALUMINA CERAMIC grade mainly applicable for finishing cast iron and steel in higher surface speed operations. Available with hole for pinlock.
NS400	Our STANDARD BLACK CERAMIC grade is a composite with Alumina Matrix containing Titanium Carbide which is known for it's excellent wear and strength characteristics. Available with hole for pinlock.
NS405	Our BLACK CERAMIC grade for cutting high hard metals (Rc58 and above), chilled cast iron and powdered metals. This insert has replaced some grinding operations in hardened steel (Rc 58-62). Available with hole for pinlock.
NS405C	Our GOLD-COATED BLACK CERAMIC grade for cutting metals with a hardness of Rc58 and above; also chilled irons. A smart choice compared to PCD or CBN. Equivalent/superior to Kennametal's Kyon 4400, Ceratip's A66N, and Toshiba's LX-11. Available with hole for pinlock.

Cermet

Part No.	Description
NS428	Our HARDEST CERMET grade recommended for turning, boring, threading and grooving. The best choice for finish machining of steels, stainless steels and cast irons.
NS429	Our TOUGHEST CERMET grade is tough enough for milling and light roughing; also turning of carbon, alloy and stainless steels, as well as ductile and cast irons.
NS430	Our BEST OVERALL 'SUPER' CERMET grade with the widest application area is relatively tough, but hard. It is recommended for turning, boring, threading, and grooving. The best choice for semi roughing to finishing of carbon, alloy and stainless steels, and cast irons. Also suitable for light milling of cast iron and steels.

Silicon Nitride

Part No.	Description
NS482	Our MEDIUM SILICON NITRIDE grade. Great for general purpose machining of irons. Available with hole for pinlock.
NS483	Our TOUGHEST SILICON NITRIDE. Great for HIGH-SPEED IRON CUTTING with VERY HEAVY INTERRUPTIONS in milling, turning, boring and facing. Available with hole for pinlock.
NS462	One of our NEWEST and BEST OVERALL SILICON NITRIDE grades. Great for HIGH-SPEED IRON CUTTING with HEAVY INTERRUPTIONS in milling, turning, boring and facing. It's very hard, but tough also. Available with hole for pinlock.
NS484	Our NEWEST SILICON NITRIDE grade. Very hard grade with excellent wear resistance. Great for high production machining of any iron.
NS461	One of our HARDEST SILICON NITRIDE grades. Great for HIGH-SPEED IRON CUTTING in continuous cuts or slight interruptions in turning, boring and facing. Available with hole for pinlock.
NS462	Our SILICON NITRIDE grade for MILLING cast iron. It is also a good grade for turning, boring and facing of cast irons. Its high fracture toughness and excellent thermal shock resistance make it a good choice in adverse conditions, such as rough scale interrupted cuts. Available with hole for pinlock.
NS462J	Our HARDEST SILICON NITRIDE grade for turning, boring and facing of cast irons. This grade is equivalent/superior to Toshiba's FX-105 and the microwave MW-43. Available with hole for pinlock.
NS447	Our SILICON NITRIDE grade for cutting EXOTIC AEROSPACE METALS such as Waspaloy, Hastelloy, Stellite, etc. Available with hole for pinlock.
