Description
Product Overview
The ToolFlo FLG 3031R-CB carbide grooving inserts are precision-engineered for high-performance cutting in standard steels and 400 series stainless. Featuring an AC50C PVD TiAlN coating, these inserts offer exceptional wear resistance and thermal stability. Designed with a .031″ wide groove, they excel in face grooving and threading applications at medium to high SFM speeds. Suitable for dry machining environments, these inserts reduce tool change frequency and maintain dimensional accuracy over extended use.
Usage
These inserts are ideal for industrial machinists working with CNC lathes or turning centers in manufacturing facilities. They perform reliably in both production and prototyping environments, especially where dry machining is preferred to reduce coolant costs and environmental impact. Common applications include automotive parts, aerospace components, and general metal fabrication requiring precise groove dimensions.
