Iscar 6002425 Dgn 6303C IC-328 Carbide Cutoff Insert

Product Description

The ISCAR 6002425 is a solid carbide cutoff and grooving insert from the Do-Grip series, identified by catalog designation DGN 6303C in grade IC-328. The insert features a 0.250 inch (6.35 mm) cutting width, a neutral lead angle, a 7-degree relief angle, and a 0.014 inch (0.35 mm) corner radius. The PVD coating in IC-328 grade is formulated for demanding workpiece materials, particularly superalloys. It is a double-ended insert held in place by a clamp-style toolholder. Licensed machinists and CNC operators install this insert in grooving and parting applications where precise width control and edge integrity are critical.

This insert is designed for grooving and parting operations on CNC lathes and turning centers. Its primary workpiece material rating covers superalloys along with steel and stainless steel applications per ISO material codes P, M, and S. The Do-Grip clamping system secures the insert mechanically, eliminating the need for screws and allowing fast indexing. The double-ended geometry doubles usable cutting edges per insert, making it well suited for production environments where tooling cost per part matters.

Key Features

• Solid carbide construction with PVD coating in IC-328 grade for extended tool life in superalloy and steel cutting
• 0.250 inch (6.35 mm) cutting width for consistent groove and parting dimensions
• Double-ended insert provides two usable cutting edges per piece
• Neutral lead angle and 7-degree relief angle reduce cutting forces and improve chip clearance
• C-style chipbreaker geometry controls chip flow in grooving and parting cuts
• Clamp-style holding method via Do-Grip toolholder for secure, repeatable seating
• Conforms to ISO 13399 standards for insert identification and interchangeability

Compatibility

Designed for use with Do-Grip series clamp-style grooving and parting toolholders that accept the DGN insert style in size code 6303. Compatible with ISO material grades C2, C3, C5, and C6 application ranges.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the Do-Grip toolholder pocket is clean and free of chips before seating the insert, as debris under the insert will affect cutting geometry and edge life. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert style.
