Iscar’s IC806 is a Sumotec PVD-coated turning grade for machining high-temperature alloys, especially Inconel 718. The grade belongs to a family of nickel-based super alloys used extensively for applications where the ability to withstand high temperatures and high corrosion resistance properties are required. The material is widely used in the aerospace industry for engine components as well as in various oil industry sectors.

The grade uses a titanium-aluminum-nitride coating as well as Iscar’s Sumotec coating in order to provide resistance to wear, chipping, notching and breakage while working in Inconel 718, whose high tensile strength can produce very high temperatures on cutting edges. IC806 has a hard submicron substrate with PVD coating and a special post-coating treatment that is said to provide substantially improved tool life and better reliability.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
