JW Blade CNMG120404-GM JT4125 For Steel Parts Cutting/black Wear-resistant

JW CNMG120404-GM JT4125 Black Wear-Resistant CNC Insert for Steel Machining

Manufactured by JW Tools, this CNMG120404-GM 80° diamond turning insert is equipped with a GM-type chipbreaker and premium JT4125 carbide grade. It features a black wear-resistant coating, specially engineered for roughing and semi-finishing of carbon steel, alloy steel and structural steel.

The JT4125 grade combines a tough tungsten carbide substrate with thick multi-layer CVD black coating, delivering excellent abrasion resistance, edge toughness and thermal stability. It effectively resists crater wear and impact fracture in both continuous and interrupted steel cutting.

Its double-sided diamond structure provides 4 usable cutting edges per insert, significantly boosting cost efficiency for high-volume production. Fully interchangeable with standard CNMG tool holders, it is widely applied in machinery, automotive, mold and hardware industries.
