Sumitomo 19P7CCE Turning Insert VNMG332 AC8025P Carbide

Product Description

The SUMITOMO 19P7CCE is a solid carbide CVD-coated turning insert designed for precision metal turning operations on CNC and manual lathes. Carrying ANSI insert code VNMG332 and ISO code VNMG160408, this insert features a 35-degree diamond (rhombic) shape with a negative rake and negative side clearance. The AC8025P grade delivers high wear-resistance to moderate wear-resistance and toughness, making it well suited for steel and cast iron workpieces. Corner radius measures 0.0313 inches (1/32 inch), and the inscribed circle diameter is 0.375 inches (3/8 inch). Licensed machinists and CNC operators install this insert in appropriate toolholders for finishing and light machining applications.

This insert is intended for finishing and light machining passes on steel (ISO material group P) and cast iron (ISO material group K) workpieces. The ESE chip breaker geometry promotes controlled chip evacuation during low-depth, tight-tolerance cuts. It is held in place using a clamp or pin-type toolholder. The neutral hand orientation allows use in both left- and right-hand setups where the toolholder geometry permits. Typical applications include external turning, facing, and contouring in production and job-shop environments.

Key Features

• AC8025P CVD-coated carbide grade for high wear-resistance on steel and moderate wear-resistance on cast iron
• 35-degree diamond (rhombic) insert shape for sharp cutting geometry in finishing operations
• ESE chip breaker optimized for finishing and light machining passes
• Negative rake with negative side clearance for rigid, stable cutting action
• Neutral hand orientation for flexible left- or right-hand toolholder compatibility
• Meets ANSI and ISO 13399 standards; ISO code VNMG160408N-SE

Compatibility

Designed for use in VNMG-style toolholders that accept a 332 (ANSI) or 160408 (ISO) size insert with clamp or pin holding method. Verify toolholder pocket specifications before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC technician. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torque wrench and clamp screw per the toolholder manufacturer's specification — do not overtighten the clamp screw, as this can fracture the insert. Inspect the insert pocket for debris or damage before seating the new insert.
