Sumitomo 19DYW29 Turning Insert CCMT32.52ESU AC700G Carbide

Product Description

The SUMITOMO 19DYW29 is a CCMT-style indexable turning insert manufactured from solid carbide and coated with aluminum oxide (Al2O3) via CVD process under the AC700G manufacturer grade. The insert features an 80-degree diamond shape, a 3/8-inch inscribed circle, and a 1/32-inch corner radius, making it well suited for precision turning operations where tight tolerances and consistent chip control are required. The ESU chip breaker geometry and positive rake angle of 8 degrees support stable cutting action across a range of feed rates. The neutral hand orientation allows flexible toolholder pairing. This insert is sold individually and requires a minimum order of 10 units.

The 19DYW29 is designed for turning applications on cast iron and steel workpieces, covering material grades C7 and C8. The AC700G grade with Al2O3 CVD coating provides thermal resistance and wear performance suited to both continuous and interrupted cuts on ferrous materials. Typical applications include OD turning on CNC lathes in production and job-shop environments. The insert seats via screw-holding method and conforms to ANSI and ISO 13399 standards, ensuring compatibility with standard CCMT toolholder systems. ISO code CCMT09T308N-SU cross-references this insert for sourcing and replacement purposes.

Key Features

• AC700G solid carbide grade with Al2O3 CVD coating for thermal and wear resistance on ferrous materials
• ESU chip breaker geometry promotes controlled chip formation at standard turning feeds
• 80-degree diamond insert shape (CCMT style) with 7-degree relief angle and positive rake for reduced cutting forces
• Neutral hand orientation compatible with a wide range of standard CCMT screw-lock toolholders
• Conforms to ANSI and ISO 13399 standards; ISO code CCMT09T308N-SU for cross-reference
• Screw-holding method provides secure insert seating and repeatable positioning

Compatibility

Designed for use in standard CCMT screw-lock toolholders accepting a 3/8-inch inscribed circle insert. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P), material grades C7 and C8. Cross-references to ISO code CCMT09T308N-SU and ANSI code CCMT32.52ESU.

Installation Notes

Installation is performed by machining professionals using standard indexable toolholder hardware. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or debris before placing the new insert to ensure proper seating and accurate tool offset registration.
