Mitsubishi 461456 Ccgt Carbide Turning Insert 1/4 in Ic

Product Description

The MITSUBISHI 461456 is a CCGT-style indexable carbide turning insert designed for precision metal cutting in CNC and manual lathe applications. Featuring an 80-degree diamond (rhombic) insert shape with a 7-degree relief angle and a 0.40 mm (1/64 inch) corner radius, this insert is optimized for finishing and medium machining operations. The HTI10 grade carbide substrate is uncoated (bright finish), delivering high wear resistance with moderate toughness. It carries a neutral hand orientation and provides two usable cutting edges per insert. Installed by machinists and toolroom professionals, this insert seats into compatible CCGT toolholders used in production and job-shop turning.

This insert is suited for turning cast iron (ISO material group K) and aluminum or non-ferrous materials (ISO material group N), where high wear resistance is the primary requirement. The AZ chip breaker geometry supports finishing and medium machining passes, producing controlled chip formation at lighter depths of cut and moderate feed rates. Typical applications include finish turning of aluminum alloy components, cast iron housings, and non-ferrous bar stock on CNC turning centers and manual lathes.

Key Features

• HTI10 carbide grade with bright/uncoated finish for high wear resistance in non-ferrous and cast iron cutting
• CCGT insert style with 80-degree diamond shape and 7-degree positive relief angle for reduced cutting forces
• 0.40 mm (1/64 inch) corner radius for fine surface finish on finishing passes
• AZ chip breaker geometry optimized for finishing and medium machining operations
• Neutral hand orientation for flexible toolholder compatibility
• Two cutting edges per insert for extended tool life per unit

Compatibility

Designed for use in toolholders accepting CCGT21.51 (ANSI) or CCGT060204 (ISO) insert geometry with a 1/4 inch inscribed circle and positive side clearance. Confirm toolholder pocket specifications before installation.

Installation Notes

Installation is performed by machinists using the appropriate torque wrench and insert screw specified by the toolholder manufacturer. Power down and lock out the machine spindle before seating or replacing inserts. Inspect the toolholder pocket for debris or damage that could affect insert seating and cutting-edge alignment. Follow the toolholder manufacturer's clamping torque guidelines to avoid insert cracking or improper seating.
