Iscar 6405248 Grooving Insert 0.1575 in Cut-grip

Product Description

The ISCAR 6405248 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the Cut-Grip series standard, this double-ended insert carries an IC8250 grade with a CVD-applied Al2O3 coating and a UR chip breaker geometry. The cutting width measures 0.1575 inches (4.00 mm), and the corner radius is 0.0787 inches (2.00 mm). A positive rake angle of 8 degrees supports cleaner chip formation and reduced cutting forces. The insert is clamp-held and suits right-hand cutting orientations. Machinists and CNC operators working in job shops and production turning environments install this insert type.

This insert is rated for primary use on stainless steel (ISO material code M) and steel (ISO material code P), making it a practical choice for general turning operations on those alloys. The double-end design extends usable insert life by providing two cutting edges per insert. Its compact overall length of 0.6181 inches (15.70 mm) and overall width of 0.1575 inches fit standard Cut-Grip toolholders used in both light and moderate-duty turning applications. This insert is sold individually and must be ordered in multiples of 10.

Key Features

• Solid carbide construction with CVD Al2O3 coating for heat and wear resistance on steel and stainless steel
• IC8250 manufacturer grade engineered for consistent performance on ISO M and P workpiece materials
• UR chip breaker geometry promotes controlled chip evacuation during grooving cuts
• Double-end design provides two usable cutting edges per insert
• Positive 8-degree rake angle reduces cutting forces and tool pressure
• Conforms to ISO 13399 tooling data standards for integration with CAM and tool management systems

Compatibility

Designed for use with Cut-Grip series clamp-style toolholders that accept GIPI insert style inserts with size code 40020. Confirm toolholder compatibility with the insert style and size code before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to tighten the clamping screw — do not overtighten. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper seating and edge repeatability.
