Ingersoll Cutting Tools 5700785 Ceramic Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 5700785 is a VNGA332 AB30 ceramic turning insert designed for precision metal cutting on CNC lathes and turning centers. It features an Al2O3 and TiCN PVD coating applied over a ceramic substrate, delivering heat resistance and wear performance suited for interrupted and continuous cuts. The insert has a 35-degree diamond shape, a neutral hand orientation, and a 0.031-inch corner radius. With four usable cutting edges and a negative rake geometry, this insert maximizes tool life per indexing cycle. It is installed and replaced by machinists and CNC operators working in production turning environments.

This insert is engineered for turning cast iron and hardened steel workpieces, where ceramic tooling outperforms carbide in high-speed, thermally demanding applications. The VNGA geometry with a negative rake and zero-degree relief angle (clearance code N) is well suited to rigid setups on production lathes. The chip breaker designation A and the inscribed circle of 3/8 inch (0.375 inches) make it appropriate for moderate depth-of-cut passes up to 0.4665 inches on medium to large diameter workpieces. Sold individually; minimum order quantity is 10 pieces.

Key Features

• Al2O3 and TiCN PVD ceramic coating for extended wear resistance on hard and abrasive materials
• 35-degree diamond insert shape (VNGA) with negative rake for stable, high-speed turning
• Four cutting edges per insert for efficient cost-per-edge value
• 0.031-inch corner radius balances edge strength with surface finish quality
• Maximum depth of cut of 0.4665 inches for versatile stock removal
• Clamp-style insert holding compatible with standard VNGA toolholders

Compatibility

Designed for use in VNGA-style clamp toolholders accepting a 3/8-inch inscribed circle, 35-degree diamond insert. ANSI code VNGA332AB30; ISO equivalent VNGA160408 AB30. Primary workpiece material codes H (hardened steel) and K (cast iron).

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct clamp screw torque as specified by the toolholder manufacturer - do not overtighten, as ceramic inserts are brittle and sensitive to clamping stress. Inspect the toolholder pocket and clamp for wear or debris before seating a new insert.
