Value Collection 111030006 SPG422 Carbide Turning Insert

Product Description

The VALUE COLLECTION 111030006 is a solid carbide turning insert designed for use on CNC lathes and manual turning centers. Manufactured to ANSI insert code SPG422 and ISO insert code SPG120308, this uncoated bright-finish insert features a 0.5-inch inscribed circle, a 1/8-inch thickness, and a 1/32-inch (0.0315-inch) corner radius. The square insert shape (S) with a 90-degree included angle and 11-degree relief angle provides positive side clearance and a flat-top chip breaker geometry. It is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for turning operations on ferrous workpiece materials in the P material group classification. The I55 manufacturer grade with C5 and C6 carbide material grades makes it appropriate for medium to finishing passes on steel and similar materials. The clamp-style holding method is compatible with standard SPG-style toolholders, and the flat-top geometry handles a range of chip formation conditions in both roughing and semi-finish turning applications.

Key Features

• ANSI code SPG422 and ISO code SPG120308 for broad toolholder compatibility
• Solid carbide construction in material grades C5 and C6
• Uncoated bright finish for sharp edge retention on finishing cuts
• 90-degree square insert shape with positive side clearance (clearance code P)
• 11-degree relief angle with 1/32-inch corner radius for reduced cutting forces
• Flat-top chip breaker geometry with clamp-style insert holding method

Compatibility

Designed for use with SPG-style turning toolholders that accept a square insert with a 0.5-inch inscribed circle and clamp-style retention. Verify toolholder pocket geometry against ANSI code SPG422 before installation.

Installation Notes

Installation is performed by machinists using standard insert clamps and torx or hex keys appropriate to the toolholder manufacturer's specifications. Power down and lock out the lathe spindle before seating or indexing the insert. Inspect the toolholder pocket for wear or debris before installing a new insert. Follow the toolholder manufacturer's clamping torque guidance and confirm insert seating is flush before resuming cutting operations.
