Value Collection 111030036 SPG422 Carbide Turning Insert

Product Description

The VALUE COLLECTION 111030036 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Manufactured to ANSI insert code SPG422 and ISO code SPG120308, this insert features a TiC and TiN multilayer coating applied via CVD process, providing wear resistance and extended tool life across a range of workpiece materials. The insert geometry is square (S-shape) with a 90-degree included angle, an 11-degree relief angle, a 0.5-inch inscribed circle, and a 1/32-inch (0.0315 inch) corner radius. The flat-top chip breaker design and positive side clearance suit finishing and semi-finishing operations. Machinists and tooling technicians specify this insert for general-purpose turning where coating durability and consistent edge geometry are required.

This insert is suited for turning applications on ferrous metals and stainless steels, corresponding to ISO primary workpiece material codes M and P. It is used in production and job-shop environments on CNC turning centers and manual lathes where a clamped, positive-clearance insert is appropriate. The CVD-coated carbide grade TCN55 covers material grades C5, C6, and C7, making it applicable across a broad range of steel and stainless turning scenarios. The flat-top, no-chip-breaker (N) geometry is appropriate where chip control is managed through feed and speed selection rather than molded breaker geometry.

Key Features

• ANSI insert code SPG422 with ISO equivalent SPG120308 for straightforward replacement sourcing
• CVD-applied TiC and TiN multilayer coating for wear resistance and extended edge life
• Square insert shape with 90-degree included angle and positive 11-degree relief angle
• 0.5-inch inscribed circle and 1/32-inch corner radius for consistent dimensional reference
• Flat-top chip breaker and clamp-style holding method for stable seating in standard toolholders
• Covers material grades C5, C6, and C7 for versatility across steel and stainless applications

Compatibility

Designed as an OEM-style replacement or direct-specification insert for SPG-style clamped toolholders accepting a square insert with a 0.5-inch inscribed circle and 1/8-inch insert thickness, per ANSI size code 422 and ISO size code 120308.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician with the machine powered down and in a locked-out state before indexing or replacing inserts. Ensure the toolholder pocket and clamping screw are free of chips and debris before seating the insert. Refer to the toolholder manufacturer's torque specification for the clamp screw. Follow applicable shop safety procedures and machine tool operating standards when setting tool offsets after insert change.
