PVD Coated Double-Sided Carbide Insert for Heavy-Duty Steel Milling CNC Milling Tool

Product Overview

The GESAC SNMU120612GM GA4230 is a high-performance double-sided square indexable carbide milling insert from GESAC (Xiamen Golden Egret Special Alloy Co., Ltd.) – a leading Chinese manufacturer of premium tungsten carbide cutting tools. Designed for heavy roughing to semi-finishing of steels, stainless steels, cast irons, and high-hardness materials (up to HRC 55), it features a GM chipbreaker and robust GA4230 PVD coating for exceptional impact resistance, chip control, and long tool life in demanding CNC milling applications.

Key Features
  • Model: SNMU120612GM GA4230
  • Brand: GESAC (Xiamen Golden Egret, China)
  • Geometry: SNMU = Square, double-sided, 4 usable edges, negative rake angle
  • Dimensions: 12 = IC 12.7 mm; 06 = thickness 6.35 mm; 12 = corner radius 1.2 mm
  • Chipbreaker: GM – optimized for heavy cutting, large chip space, efficient evacuation
  • Grade: GA4230 – high-strength ultrafine carbide substrate with PVD coating
  • Coating: Advanced PVD coating, excellent heat, wear, and adhesion resistance
  • Edges: 4 usable cutting edges (double-sided design), high rigidity for interrupted cuts
Workpiece Materials
  • Carbon steels (P20–P40) – primary
  • Stainless steels (M20–M30, 304/316/420)
  • Alloy steels (4140, 42CrMo4, HRC < 55)
  • Grey & ductile cast irons (K10–K30)
  • Hardened steels (HRC 50–55)
Typical Applications
  • Heavy face milling & shoulder milling
  • High-feed milling & roughing (large depth of cut)
  • Slotting, ramping, and profiling (interrupted cuts)
  • General-purpose CNC milling (mass production & heavy job shops)
  • Dry machining (excellent thermal stability)
