Iscar 5508070 CNMA544 IC5010 Carbide Turning Insert

Product Description

The ISCAR 5508070 is a CNMA544-style solid carbide turning insert carrying the IC5010 manufacturer grade and a tri-layer CVD coating of TiCN, Al2O3, and TiN. The insert features an 80-degree diamond shape with a 0 degree relief angle (clearance code N, tolerance code M) and a 1/16-inch corner radius. The inscribed circle measures 5/8 inch, insert length is 15.90 mm (0.626 inches), and insert thickness is 1/4 inch. It is designed for single-point turning operations on CNC and manual lathes and is installed by machinists and tool-and-die professionals in production and job-shop environments.

This insert is engineered primarily for turning cast iron workpieces, consistent with ISO material group K. It belongs to the Isoturn series and carries chip breaker designation A with insert size code 544. The CVD tri-layer coating provides wear resistance and thermal stability suited to continuous and interrupted turning passes on gray, ductile, and compacted graphite cast iron at moderate to high cutting speeds. It is held in toolholders using a clamp-and-pin method, compatible with standard CNMA-style pockets.

Key Features

• CVD tri-layer coating — TiCN base, Al2O3 mid-layer, TiN top coat — for crater and flank wear resistance on cast iron
• 80-degree diamond insert shape (shape code C) provides a strong cutting edge geometry
• IC5010 carbide grade optimized for ISO K (cast iron) primary workpiece material
• 1/16-inch (0.0625 inch) corner radius balances surface finish quality with edge strength
• Maximum depth of cut: 10.00 mm (0.394 inches)
• Clamp and pin holding method for secure seating in CNMA toolholder pockets
• Compliant with ISO 13399 cutting tool data representation standard

Compatibility

Designed as an OEM-style replacement and standard production insert for CNMA544-pocket toolholders within the ISCAR Isoturn series. Compatible with any toolholder accepting a CNMA style insert with a 5/8-inch inscribed circle and clamp-and-pin retention.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket and clamp surfaces are clean and free of chips before inserting to prevent seating errors that affect cutting geometry. Follow the toolholder manufacturer torque recommendations for the clamp screw — do not overtighten, as this can crack the carbide substrate.
