Value Collection ICC18540H Turning Insert SPG322 I55

Product Description

The VALUE COLLECTION ICC18540H is a solid carbide turning insert designed for single-point turning operations on CNC lathes and manual turning centers. Manufactured to ANSI insert code SPG322 and ISO insert code SPG090308, this insert features a square shape (S), a positive side clearance, and a bright uncoated finish designated grade I55. The 3/8-inch inscribed circle and 1/32-inch corner radius make it suited for moderate-depth turning passes where precision geometry and edge integrity are critical. It is held in place by a clamp-style toolholder and operates with a flat-top chip breaker profile, meaning chip control relies on workpiece material and cutting parameters rather than a molded breaker geometry.

This insert is intended for use on ferrous workpiece materials classified under primary workpiece material code P, with material grades C5 and C6. Typical applications include finish and semi-finish turning of steel and cast iron components in production and job-shop environments. Machinists and CNC operators working with clamp-style SPG-compatible toolholders will find this insert a direct fit for standard external turning, facing, and light profiling operations. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction with bright uncoated finish, grade I55
• Square insert shape (S) with 90-degree included angle and positive side clearance
• 3/8-inch (0.375-inch) inscribed circle for consistent seating in SPG-style pockets
• 1/32-inch (0.0313-inch) corner radius suitable for moderate-radius finish passes
• Flat-top chip breaker for straightforward edge geometry without complex chip-forming features
• Clamp-style holding method compatible with standard SPG toolholder seats

Compatibility

Designed for use in clamp-style toolholders accepting SPG322 inserts with an S-style square pocket. Conforms to ANSI insert code SPG322 and ISO insert code SPG090308. Intended for primary workpiece material code P applications at material grades C5 and C6.

Installation Notes

Machinist or CNC operator installation. Before indexing or replacing inserts, confirm the machine spindle is fully stopped and the toolholder is secured in the turret or tool post. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when securing the clamping finger — do not overtighten by feel alone. Inspect the insert pocket and clamp for chips or debris before seating a new insert, as contamination in the pocket will affect insert height and cutting accuracy.
