Iscar 5500347 Dcmt 3-2-14 IC20 Turning Insert Solid Carbide

Product Description

The ISCAR 5500347 is a solid carbide turning insert in the DCMT style, designed for external and internal turning operations on CNC and manual lathes. This uncoated carbide insert carries the IC20 grade designation and belongs to ISCARs Isoturn series. It features a 55-degree diamond insert shape, a positive rake geometry, and a screw-style insert holding method. The corner radius measures 1/32 inch (0.0315 inch), and the inscribed circle diameter is 3/8 inch (0.3748 inch). Insert length is 11.60 mm (0.4567 inch), and insert thickness is 5/32 inch (0.1563 inch). These dimensions make it a compact, precision-ground insert suited for finishing and semi-finishing passes in controlled cutting conditions.

This insert is intended for use in turning applications where uncoated solid carbide is preferred, such as when cutting non-ferrous metals, cast iron, and certain stainless and heat-resistant alloys. Primary workpiece material designations include K (cast iron), M (stainless steel), and N (non-ferrous). The DCMT geometry with a 7-degree relief angle and positive rake supports lower cutting forces, making it a common choice for light-to-medium material removal on precision turning centers and toolroom lathes in both production and maintenance environments.

Key Features

• 55-degree diamond (D) insert shape with positive rake for reduced cutting forces
• IC20 uncoated solid carbide grade suited for non-ferrous, cast iron, and stainless applications
• Corner radius of 1/32 inch (0.0315 inch) for fine finishing and controlled edge geometry
• Screw-style clamping (DCMT style) for secure, repeatable indexing
• Maximum depth of cut of 3.00 mm (0.1180 inch)
• Conforms to ISO 13399 standard for tool data representation

Compatibility

Designed for use in DCMT-style screw-clamp turning toolholders within the ISCAR Isoturn series. Specific toolholder compatibility should be verified against the ISCAR Isoturn toolholder catalog using the DCMT 3-2-14 insert seat specification.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Before indexing or replacing inserts, power down the machine and confirm the spindle is fully stopped. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturers specified feel — do not overtighten, as this can crack the carbide insert. Verify insert seating and shim condition before returning the tool to service.
