Iscar 3347725 Carbide Cutoff Insert 3mm Tang-grip

Product Description

The ISCAR 3347725 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the Tang-Grip self-gripping series, this single-end insert features a 3.00mm (0.118 inch) cutting width with a neutral lead angle and a 0.40mm (0.0157 inch) corner radius. It carries a TiAlN/AlTiN/TiN PVD coating applied under the IC830 manufacturer grade, optimized for cutting superalloys and other demanding workpiece materials. Machinists and tool-and-die professionals installing this insert will find it suited for tight-tolerance groove work where consistent width and reliable clamping are critical.

This insert is intended for grooving and parting applications across a range of workpiece materials, with the primary designation targeting superalloys (ISO material codes M, P, and S). The HF chipbreaker geometry is engineered for controlled chip formation in these materials. The Tang-Grip self-grip holding method provides secure seating in compatible Tang-Grip toolholders without additional clamping hardware, making tool changes straightforward on the shop floor. Typical installations include OD grooving and full parting cuts on production turning equipment.

Key Features

• Solid carbide construction with IC830 PVD-coated grade (TiAlN/AlTiN/TiN) for wear resistance in superalloy cutting
• 3.00mm cutting width (0.118 inch) with a tight width tolerance of 0.04mm for accurate groove sizing
• 0.40mm (0.0157 inch) corner radius for controlled groove profile
• Neutral lead angle and neutral hand for straightforward radial parting and grooving setups
• HF chipbreaker geometry designed for effective chip control in difficult-to-machine materials
• Tang-Grip self-grip holding method — no extra clamps required in compatible toolholders

Compatibility

Designed for use in Tang-Grip series toolholders compatible with TAG-style inserts. Verify toolholder pocket specifications against the 3mm insert size code before installation. Conforms to ISO 13399 standards for cutting tool data representation.

Installation Notes

Installation should be performed by a qualified machinist with the machine in a full stop and lockout-tagout procedures applied before accessing the turret or toolholder. Seat the insert fully into the Tang-Grip pocket until the self-grip mechanism engages; do not force the insert with excessive lateral pressure. Inspect the insert seat and toolholder pocket for chips or debris before each insert change to maintain accurate seating and prevent premature edge failure.
