Iscar 5550497 VCMT330SM IC807 Turning Insert 3/8 Inch Ic

Product Description

The ISCAR 5550497 is a solid carbide turning insert in the VCMT330SM geometry, designed for precision single-point turning operations on CNC lathes and turning centers. It carries the IC807 grade designation, a submicron solid carbide substrate with a PVD-applied TiAlN coating that delivers heat resistance and edge wear performance across a broad range of workpiece materials. The insert measures 0.6535 inches in length with a 3/8 inch (0.3750 inch) inscribed circle and a 0.008 inch corner radius. The SM chip breaker geometry promotes positive rake cutting action, helping to control chip formation during light to moderate depth-of-cut operations. Licensed machinists and CNC programmers select this insert for jobs where dimensional accuracy and surface finish consistency are critical.

The 5550497 is suited for turning ferrous metals, stainless steels, exotic alloys, and cast irons, as indicated by its primary workpiece material codes H, K, M, P, and S. The VCMT330SM geometry — a 35-degree diamond shape with a 7-degree relief angle — makes it well-matched for finish and semi-finish turning passes where positive rake and a sharp edge are required. It belongs to ISCAR's Isoturn series and is used in screw-clamp toolholders that accept VCMT-style inserts. The maximum depth of cut is 0.0984 inches (2.50 mm), placing this insert in finish to light semi-finish turning applications on both horizontal and vertical turning configurations.

Key Features

• IC807 submicron solid carbide grade with PVD TiAlN coating for extended tool life across mixed-material applications
• SM chip breaker geometry with positive rake for efficient chip control in finish and semi-finish turning
• 35-degree diamond insert shape (VCMT) with 7-degree clearance angle for access in profiling and contouring operations
• 0.008 inch corner radius balances edge strength and surface finish capability
• Screw-clamp insert holding method provides secure seating and repeatable indexing in compatible toolholders
• Conforms to ISO 13399 tooling data standards for integration with CAM and tool management systems

Compatibility

Designed for use in screw-clamp VCMT-style turning toolholders within the ISCAR Isoturn series. Compatible with setups targeting workpiece material groups H, K, M, P, and S per ISO material classification.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and all axes locked out per site lockout/tagout procedures. Seat the insert fully in the toolholder pocket before engaging the clamping screw, and verify the insert is flush and secure prior to any trial cut. Do not exceed the rated maximum depth of cut of 0.0984 inches without consulting ISCAR cutting data recommendations. Index or replace the insert at the first sign of edge chipping, built-up edge, or surface finish degradation to avoid workpiece damage or toolholder wear.
