Kennametal 7093251 Dnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093251 is a DNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Built from a solid carbide substrate with an AlTiN coating and KCU10B manufacturer grade, this insert delivers thermal resistance and edge durability across a range of turning applications. The diamond-shaped insert geometry features a 55-degree included angle, a 0.40 mm corner radius, and four available cutting edges, making it a cost-effective option for shops running high production volumes. It is installed in standard DNMG-compatible toolholders and is handled by machinists and CNC setup technicians.

This insert is suited for external and internal turning operations on ferrous and non-ferrous workpiece materials where a sharp, neutral-hand geometry is required. The FW chip breaker geometry assists with chip control during light to medium turning passes. The 0.40 mm corner radius makes it appropriate for finishing operations or applications with tighter shoulder transitions. Each package contains one insert, with a minimum order quantity of five units.

Key Features

• DNMG insert style with diamond shape and 55-degree included angle for versatile turning geometry

• FW chip breaker for controlled chip evacuation during light to medium depth-of-cut passes
• Neutral hand orientation fits standard DNMG right- or left-hand compatible toolholders
• Four cutting edges per insert extend usable tool life per unit
• 0.40 mm corner radius suited for finishing and contour turning applications

Compatibility

Designed as a replacement-style turning insert for use in standard DNMG-compatible toolholders accepting an inscribed circle of 0.5000 inches and an insert thickness of 0.1875 inches. Confirm toolholder seat geometry and clamping style before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC technician with the machine powered down and the spindle locked. Use the appropriate torque wrench or insert-clamping tool specified by the toolholder manufacturer when securing the insert clamp or screw. Inspect the toolholder seat and clamping surfaces for debris or wear before seating a new insert. Never attempt to re-sharpen or modify a coated carbide insert.
