Value Collection 111030136 SPG423 Carbide Turning Insert

Product Description

The VALUE COLLECTION 111030136 is a solid carbide turning insert designed for precision metal cutting operations on CNC and manual lathes. Manufactured to the ANSI insert code SPG423 and ISO code SPGN120312, this insert features a square shape (S) with a 90-degree included angle and an 11-degree relief angle for positive side clearance. It carries a TCN55 grade designation and is CVD-coated with TiC and TiN layers to extend wear resistance and tool life during moderate to heavy turning applications. Qualified machinists and tool-and-die technicians install this insert type in compatible indexable turning toolholders.

This insert is suited for turning operations on steel and stainless steel workpiece materials, corresponding to ISO primary workpiece material codes P and M. The flat-top chip breaker geometry (code N) promotes controlled chip flow in continuous cutting passes. Typical applications include OD turning, facing, and light profiling on ferrous metals in production and job-shop environments. The clamp-style holding method (code C) is compatible with standard SPG-style toolholder pockets.

Key Features

• Solid carbide substrate with CVD-applied TiC and TiN coating for extended wear resistance
• Square insert shape with 90-degree included angle and 11-degree positive relief angle
• 0.5-inch inscribed circle diameter for standard SPG-pocket toolholders
• 3/64-inch (0.0472-inch) corner radius for general turning and light profiling
• Flat-top chip breaker (code N) promotes chip control in continuous cuts
• Material grade range C5, C6, C7 covering a broad range of ferrous turning applications

Compatibility

Designed as an OEM-style replacement insert for SPG423-style indexable turning toolholders accepting a square insert with positive clearance and clamp-style retention. Compatible toolholder pockets must conform to the SPG423 ANSI size code and SPGN120312 ISO size code specifications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when securing the insert in the pocket. Inspect the toolholder pocket and clamp for wear or damage before seating a new insert, and confirm the insert is fully seated before resuming cutting operations.
