VNMG Coated Carbide Turning Inserts for Stainless Steel

Quick Details

Product Description

Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to

chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert

for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit

of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide.

Most modern face mills use carbide inserts, as well as many lathe tools and end mills.To increase the life of carbide

tools, they are sometimes coated. Four such coatings are TiN (titanium nitride), TiC (titanium carbide), Ti(C)N

(titanium carbide-nitride), and TiAlN (titanium aluminum nitride). (Newer coatings, known as DLC (Diamond-like

carbon) are beginning to surface, enabling the cutting power of diamond without the unwanted chemical reaction

between real diamond and iron.)
