Iscar 5700623 Ceramic Turning Insert Cnga 432T Isoturn

Product Description

The ISCAR 5700623 is a CNGA 432T ceramic turning insert designed for precision finishing operations on cast iron and hardened materials. It carries an Al2O3 and TiCN ceramic coating applied via PVD process, delivering high wear resistance in demanding cutting environments. The insert measures 12.9 mm (0.508 inches) in length with a 0.5 inch inscribed circle and a 1/32 inch (0.0315 inch) corner radius. The 80-degree diamond shape and negative side clearance geometry make it well suited for stable, high-speed finishing passes where surface finish and tool life are critical. CNC machinists and turning center operators typically install this insert.

This insert is intended for finishing applications on cast iron workpieces (ISO material group K) and hardened materials (ISO material group H), where high wear resistance is the primary requirement. The maximum depth of cut is 0.40 mm (0.0157 inches), confirming its role as a light-finishing insert rather than a roughing tool. It fits standard CNGA-style toolholders that accept clamp or pin holding methods. The Isoturn series designation indicates compatibility with ISCAR Isoturn toolholder systems. ANSI insert code is CNGA 432 and the ISO insert code is CNGA 120408.

Key Features

• Al2O3 and TiCN ceramic coating via PVD process for high wear resistance
• 80-degree diamond (rhombic) insert shape with negative side clearance for stable finishing cuts
• Manufacturer grade IN420 optimized for cast iron and hardened material applications
• Maximum depth of cut of 0.40 mm (0.0157 inches) for precise finishing passes
• Chip breaker style T for controlled chip formation during finishing
• Compatible with clamp and pin insert holding methods

Compatibility

Designed for use in ISCAR Isoturn series toolholders accepting CNGA-style inserts with clamp or pin holding. ANSI insert code CNGA 432 and ISO insert code CNGA 120408 govern toolholder compatibility. Verify toolholder insert seat geometry and clamping method before installation.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians on turning centers or lathes. Power down the machine and confirm zero energy state before changing inserts. Seat the insert fully and evenly against the toolholder pocket surfaces before tightening the clamp or seating the pin, as an improperly seated insert can fracture under cutting loads. Ceramic inserts are brittle compared to carbide; avoid interrupted cuts, heavy depths of cut beyond the rated maximum, or impact loading that can cause chipping or catastrophic insert failure.
