Iscar 5568857 Turning Insert DNMG431-F3M IC806 Carbide

Product Description

The ISCAR 5568857 is a DNMG431-F3M grade IC806 carbide turning insert designed for precision metal removal in CNC and manual turning applications. The insert features an AlTiN coating applied via PVD process under ISCAR's proprietary SumoTec technology, which enhances wear resistance and thermal stability during cutting. The 55-degree diamond shape (DNMG style) delivers a positive rake geometry that reduces cutting forces. With a 0.4 mm corner radius and a maximum depth of cut of 1.50 mm, this insert is suited for finishing and semi-finishing passes on difficult-to-machine materials, particularly those in the S workpiece material group, which includes superalloys and titanium.

This insert is intended for right-hand turning operations on CNC lathes and turning centers in metalworking environments. It belongs to ISCAR's Isoturn series and carries the F3M chip breaker geometry, optimized for controlling chips during light-to-moderate material removal rates on heat-resistant alloys. Machinists and tooling engineers working on aerospace, medical, or energy components will find this insert appropriate for their finishing operations. It is sold individually with a minimum order quantity of 10 pieces.

Key Features

Compatibility

Designed as an OEM-style replacement and standard fitment insert for DNMG-style turning toolholders with a 55-degree diamond pocket accepting the 431 insert size designation. Confirm toolholder pocket geometry and clamping style before ordering.

Installation Notes

This insert is installed by a machinist or tooling technician into a compatible DNMG-style toolholder. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Use the appropriate torx or clamp screw torque per the toolholder manufacturer's specification. Inspect the insert seat and clamp for debris or wear before installation to ensure proper seating and clamping force.
