Duracarb TNMG160408 46 DC5010

• Geometry & Size: TNMG 160408 — a 60° negative (triangular) insert, inscribed circle (IC) approx. 9.52 mm, thickness ~4.76 mm, corner (nose) radius RE = 0.8 mm.
  
  Chip Breaker / Style: Type “46” chip breaker — balanced for medium to robust turning applications, delivering good chip control even under varying feeds. (Based on Duracarb catalogue families.)
  
  Grade / Coating: DC5010 – Duracarb’s high-wear, high-toughness grade (PVD/CVD-like behaviour) designed to resist abrasion, chipping, and edge fracture. While exact coating chemistry is proprietary, DC-series grades in Duracarb’s catalog are built for demanding turning. 

• Cutting Applications: Ideal for turning (external), especially medium to finishing cuts on steel, alloy steels, and general engineered parts. (Duracarb’s ISO turning line includes TNMG inserts in DC / DP grades for such use.)

• Extended Tool Life: The DC5010 grade provides superior wear resistance and toughness, meaning you change inserts less often — reducing downtime and saving costs per component.

• High Stability + Less Chipping: The 46 chip breaker ensures stable cutting, even with interrupted cuts or variable depths, with lower risk of edge fracture.

• Better Surface Finish: Consistent edge retention helps maintain high-quality surface finish, reducing rework and boosting part consistency.

• Reliable Quality: Duracarb (part of the IMC / Taegutec family) adheres to stringent quality standards (ISO 9001, etc.) in its manufacturing

This insert is particularly well-suited for:

• Automotive: Machining shafts, axles, gear blanks, engine components.

• Aerospace: Turning alloy-steel airframe parts, structural components.

• Die & Mold: Finishing and semi-finishing of mold inserts and tooling.

• General Engineering: Shafts, frames, fasteners, valve bodies, and other precision parts.
