Kennametal 7093059 Spg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093059 is a square carbide turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Built to the SPG style with a neutral hand orientation, this insert features an AlTiN (aluminum titanium nitride) coating and is manufactured in the KCU10B grade, making it well suited for demanding turning operations where heat resistance and edge retention are priorities. The insert has a 0.5 inch inscribed circle, a relief angle of 11 degrees, and delivers four usable cutting edges per insert, reducing tooling cost per edge in production environments.

This insert is appropriate for general turning applications in ferrous and non-ferrous materials where an SPG-style seat is specified. With a 90-degree included angle and a 1/32 inch (0.0313 inch) corner radius, it is suited to light to medium finishing passes. The neutral hand design allows use in both left- and right-hand toolholders equipped with the corresponding SPG-style pocket. Licensed machinists, toolroom operators, and CNC programmers typically select this insert for precision turning operations requiring tight tolerances and consistent surface finish.

Key Features

• AlTiN coating improves heat resistance and extends tool life in high-speed turning
• KCU10B carbide grade provides a balance of hardness and toughness for turning applications
• Four cutting edges per insert maximize value in production tooling setups
• 11-degree relief angle reduces flank contact and minimizes cutting force
• 1/32 inch corner radius supports finishing and light semi-finishing passes
• No chip breaker geometry for unobstructed chip flow in open-groove toolholders

Compatibility

Designed as an OEM-style replacement insert for toolholders with SPG-style square insert pockets accepting a 0.5 inch inscribed circle and 1/8 inch insert thickness.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque specifications for the clamp screw. Always index or replace inserts with the machine in a stopped and locked-out state. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to ensure proper edge height and prevent premature edge failure.
