Value Collection ICP27250B Turning Insert CNMG642 TCN55

Product Description

The VALUE COLLECTION ICP27250B is a solid carbide turning insert designed for single-point turning operations on CNC and manual lathes. Conforming to ANSI insert code CNMG642 and ISO code CNMG190608, this insert features an 80-degree diamond (rhombic) shape with a negative side clearance geometry. The inscribed circle measures 3/4 inches (0.7500 inches), insert thickness is 1/4 inch (0.2500 inches), and the corner radius is 1/32 inch (0.0312 inches). Grade TCN55 carbide construction and a G-style chip breaker make it suited for a range of turning applications across common workpiece materials. Holding method is clamp and pin.

This insert is intended for use in metalworking operations on CNC turning centers and manual lathes in industrial, toolroom, and production machining environments. It is installed by machinists and tooling technicians. Per the ANSI specification, primary workpiece material codes are M and P, covering stainless steel and carbon or alloy steel respectively. The material grade designation is C5, placing it in the finishing-to-medium turning range. Individual inserts are sold as single units with a minimum order quantity of 10 pieces.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when seating the clamp to avoid insert cracking or improper seating. Inspect the toolholder pocket and locating pin for wear or contamination before installing a new insert.
