Iscar 6004438 Cutoff Insert Tang-grip 4.05 Mm

Product Description

The ISCAR 6004438 is a solid carbide cutoff and grooving insert in the Tang-Grip series, designed for parting and grooving operations on CNC lathes and turning centers. It carries the TAGN4A insert style designation and the IC20 manufacturer grade, an uncoated carbide grade suited for universal workpiece materials including steel, cast iron, stainless, non-ferrous metals, and high-temperature alloys. The cutting width is 4.05 mm (0.1594 inches) with a neutral lead angle and a 0.24 mm corner radius. This insert uses a clamp-style holding method and is installed by qualified machinists and toolroom technicians performing parting or profile grooving work.

The 6004438 insert is used in both production and job-shop turning environments where repeatable parting and grooving performance is required. The neutral hand and neutral lead angle configuration make it adaptable across a range of groove geometries. Its universal primary workpiece material designation covers ISO material groups H, K, M, N, and S, meaning it performs on cast iron, stainless steel, carbon steel, non-ferrous, and superalloy workpieces. The A chipbreaker geometry is appropriate for standard grooving and cutoff cycles at typical production depths and feeds.

Key Features

• Tang-Grip series clamp-style insert for secure radial and axial load resistance during parting
• 4.05 mm cutting width with 0.24 mm corner radius for consistent groove profiles
• IC20 solid carbide grade, uncoated, suitable for universal workpiece materials
• Neutral lead angle and neutral hand for flexible application in standard grooving setups
• 7-degree relief angle reduces rubbing and supports clean cutoff on a range of materials
• Single-end insert; sold individually with a minimum order quantity of 10 units

Compatibility

Designed as an OEM-style replacement insert for Tang-Grip series grooving and parting toolholders accepting TAGN4A-style inserts. Verify toolholder seat specification against insert style and size code 4 before ordering.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing the insert. Ensure the Tang-Grip toolholder pocket is clean and free of chips or debris before clamping the insert. Follow the toolholder manufacturer torque guidance for the clamping screw; do not overtighten, as solid carbide inserts are brittle and can crack under excessive clamping force.
