Sumitomo 19RB297 Turning Insert VNMG332ENG AC830P Carbide

Product Description

The SUMITOMO 19RB297 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI code VNMG332ENG and ISO code VNMG160408N-UG, this insert features a 35-degree diamond shape (V) with a neutral hand orientation. The AC830P grade uses a CVD coating process for enhanced wear resistance and thermal stability. With a 3/8-inch inscribed circle and a 0.0313-inch corner radius, it is sized for medium-duty turning applications. Licensed machinists and CNC operators install this insert as part of a clamp-and-pin toolholder system. It is rated for use on stainless steel (M) and carbon and alloy steel (P) workpiece materials.

This insert fits standard VNMG-style toolholders using a clamp and pin holding method. It is suited for residential and industrial machine shop environments where consistent chip control and surface finish are required. The ENG chip breaker geometry is designed for general-purpose turning on steel and stainless steel, making it a practical choice for production turning and job shop work. The AC830P material grade aligns with C5, C5A, and C6 carbide classifications, covering a broad range of cutting conditions on steel and stainless workpieces.

Key Features

• CVD-coated AC830P solid carbide grade for extended tool life on steel and stainless steel
• 35-degree diamond insert shape (ANSI code V) with negative rake geometry
• ENG chip breaker for controlled chip evacuation in general turning operations
• Neutral hand orientation for use in both left- and right-hand toolholders
• Clamp and pin holding method compatible with standard VNMG-style toolholders
• Meets ANSI and ISO 13399 standards for interchangeability and documentation

Compatibility

Designed for use in VNMG-style toolholders with clamp and pin holding systems. Compatible with workpiece materials coded M (stainless steel) and P (carbon and alloy steel). Material grades C5, C5A, and C6 apply. Refer to the ANSI code VNMG332ENG and ISO code VNMG160408N-UG when cross-referencing toolholder and insert catalogs.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the machine powered down and all axes at a safe position. Use the appropriate torx or hex key to secure the clamp screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Never exceed the recommended depth of cut or feed rate for the grade and geometry as specified in the toolholder and insert documentation.
