Iscar 6200373 Grooving Insert HFPR4020 IC8250 4mm

Product Description

The ISCAR 6200373 is a solid carbide grooving insert from the Heliface series, designed for precision grooving and parting operations on CNC lathes and turning centers. This right-hand insert carries the HFPR4020 insert style with a 4 mm cutting width and a maximum depth of cut of 2 mm. The IC8250 grade features a PVD-applied Al2O3 coating that improves wear resistance and edge stability during interrupted or continuous cuts. A full corner radius of 2 mm and a positive rake angle of 7 degrees reduce cutting forces and minimize workpiece deflection. Machinists and CNC operators working in production environments will find this insert well suited to tight-tolerance groove work.

This insert is engineered for grooving and profiling in stainless steel and carbon steel workpieces, making it a practical choice in job shops, aerospace component shops, and general-purpose turning operations. The double-end design extends usable tool life per insert. The clamp-style insert holding method provides secure, repeatable seating in compatible ISCAR Heliface toolholders. Overall insert length is 19 mm, fitting standard Heliface slot geometries. Applications include external grooving, face grooving, and light parting on turned parts requiring controlled chip evacuation and consistent surface finish.

Key Features

• Solid carbide construction with PVD Al2O3 coating for extended wear resistance
• 4 mm cutting width with a full corner radius of 2 mm
• Maximum depth of cut range of 2 mm to 3 mm
• Positive 7-degree rake angle reduces cutting forces on stainless and alloy steel
• Double-end insert design for added value per unit
• Clamp-style holding method for secure, repeatable insert indexing

Compatibility

Designed for use in ISCAR Heliface series toolholders that accept the HFPR4020 insert style with clamp-style retention. Intended for right-hand cutting setups. Confirm toolholder slot dimensions and clamping system before installation.

Installation Notes

Installation of grooving inserts should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, locked-out condition. Use the correct torque wrench and clamp hardware specified for the Heliface toolholder to seat the insert without cracking the carbide substrate. Inspect the insert pocket for chips or burrs before seating a new insert, as debris under the insert will cause premature failure or poor tolerance. Always verify insert orientation and hand designation match the programmed tool path before resuming operation.
