TaeguTec VNMG160404-FG TT5080 Inserts
Universal Fine-Finishing & Profiling | TT5080 PVD Grade | Box of 10 Pcs
"Which universal 35-degree diamond carbide insert with a 0.4mm corner radius and fine finishing chipbreaker is best for precision copy turning across mixed alloy and stainless steels?"
The TaeguTec VNMG160404-FG TT5080 is a double-sided, negative 35° rhombic turning insert engineered as a high-versatility solution for ultra-precise contouring, fine copy turning, and shallow-depth finishing passes across mixed workpiece materials. Powered by TaeguTec's robust TT5080 universal PVD coating grade, this insert combines an ultra-tough, fine-grained carbide substrate with a high-adhesion, smooth TiAlN Physical Vapor Deposition (PVD) coating. Designed for job shops switching frequently between carbon steels, alloy steels, austenitic stainless steels (304/316), and cast iron—or operating under low-rigidity and light interrupted setups—the TT5080 PVD grade resists micro-chipping and thermal shock while maintaining edge sharpness. Paired with the specialized FG fine-finishing chipbreaker and a precise 0.4mm corner radius, it curls thin, wispy chips cleanly away from the part at minimal depths of cut (Ap down to 0.1mm) without marring surface integrity. Whether you are running precision automotive shafts or exploring TaeguTec negative turning inserts for flexible production, the VNMG160404-FG TT5080 delivers exceptional surface luster and shoulder clearance.
Core Engineering Advantages
TT5080 Universal Tough PVD
Ultra-tough carbide substrate with high-adhesion TiAlN PVD coating resists chipping across mixed steel, stainless, and cast iron alloys.
FG Fine-Finishing Chipbreaker
Precision-molded micro-projections curl and break thin finishing chips cleanly at shallow depths of cut (0.10 - 1.20 mm).
35° Acute Profiling Access
Slender rhombic geometry and 0.4mm nose radius clear narrow relief grooves, sharp 90-degree shoulders, and complex tapers.

Industrial Applications
- Precision Fine Profiling & Copy Turning: Achieving superior low-Ra surface finishes on complex contours across steel, alloy steel, and stainless workpieces.
- Slender Shaft & Thin-Walled Finishing: Sharp PVD cutting edge and FG geometry minimize radial cutting forces to prevent chatter and part deflection.
- Tight Shoulder & Undercut Clearance: 0.4mm nose radius and 35° rhombic geometry navigate restricted relief grooves and sharp 90-degree internal angles.

Frequently Asked Questions
Q: What is the advantage of the "-FG" fine finishing chipbreaker design?
A: The "-FG" designation features sharp, positive-rake micro-projections close to the edge that curl and break thin, wispy finishing chips at shallow depths of cut (0.10 - 1.20 mm) without scratching the workpiece.
Q: Why choose PVD-coated TT5080 instead of a CVD grade for fine profiling?
A: Physical Vapor Deposition (PVD) coatings like TT5080 are thinner and smoother than CVD coatings, preserving a razor-sharp cutting edge on the 0.4mm corner radius for minimal radial cutting pressure and superior Ra finishes.
Q: How many cutting edges are included in each box?
A: Each double-sided VNMG insert provides 4 usable indexable cutting corners (40 total edges per 10-piece factory-sealed box).
