Iscar 6405375 Grooving Insert TAGB608B IC806 Sumo-grip

Product Description

The ISCAR 6405375 is a solid carbide grooving insert in the Sumo-Grip series, designed for external grooving and parting operations on CNC turning centers and lathes. The insert carries ISCAR grade IC806, a submicron carbide substrate with a PVD-applied AlTiN coating engineered for cutting superalloys and titanium at elevated temperatures. With a cutting width of 5.99 mm (0.236 inches) and a maximum depth of cut of 3.61 mm (0.142 inches), it delivers consistent groove geometry in demanding aerospace and high-temperature alloy applications. The TAGB insert style features a positive rake and a chip breaker designation of B for controlled chip flow.

This insert is suited for production turning environments where superalloys, titanium, and similar high-strength materials are machined. The Sumo-Grip clamping system provides rigid insert seating, reducing deflection during interrupted or heavy grooving passes. Typical applications include aerospace component machining, medical implant turning, and high-value part production where tool life consistency and dimensional accuracy are critical. It is a single-end insert rated for re-indexing within compatible Sumo-Grip toolholders. It is installed by CNC machinists and tooling technicians.

Key Features

• IC806 submicron carbide grade with PVD AlTiN coating for superalloy and titanium cutting
• 5.99 mm (0.236 inches) cutting width with a 3.61 mm (0.142 inches) maximum depth of cut
• Positive rake geometry with B-style chip breaker for controlled chip evacuation
• Corner radius of 0.79 mm (0.031 inches) for groove-bottom definition
• Neutral hand orientation for flexible toolholder pairing
• Conforms to ISO 13399 tool data standards for CAM system integration

Compatibility

Designed for use with ISCAR Sumo-Grip series toolholders that accept TAGB-style grooving inserts. Primary workpiece material category is superalloys and titanium (ISO material code S).

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine spindle stopped and all motion axes locked. Use the appropriate ISCAR Sumo-Grip torx or hex key to seat the insert clamp to the toolholder specification. Inspect the insert pocket for chips or debris before seating a new insert, as contamination will affect insert-to-pocket contact and dimensional accuracy. Do not force the insert into the pocket; proper Sumo-Grip geometry self-locates the insert when the clamping screw is tightened correctly.
