TaeguTec VNMG160408EM TT9080 Inserts
High-Toughness Stainless Steel & Interrupted Profiling | TT9080 PVD Grade | Box of 10 Pcs
"Which 35-degree diamond carbide insert is best for interrupted cuts and tough profiling in stainless steel and heat-resistant alloys?"
The TaeguTec VNMG160408EM TT9080 is an ultra-tough, negative 35° rhombic turning insert engineered for demanding CNC copy turning, contouring, and medium-to-heavy stock removal under unstable or interrupted cutting conditions. Powered by TaeguTec's specialized TT9080 PVD coating grade, this insert combines a high-toughness, shock-absorbing sub-micron carbide substrate with an advanced nano-structured PVD shield. Because a slender 35° diamond corner is inherently vulnerable to mechanical shock and thermal fatigue, the TT9080 grade prevents chipping, micro-fractures, and Built-Up Edge (BUE) when machining austenitic stainless steels (304/316), precipitation-hardening steels, and nickel-based superalloys with cross-holes or scale. Paired with the sharp, positive-rake EM medium-turning chipbreaker and a sturdy 0.8mm nose radius, it ensures smooth chip evacuation across variable depths of cut. Whether you are contouring complex shafts with intermittent features or exploring TaeguTec negative turning inserts for heavy-duty shop environments, the VNMG160408EM TT9080 delivers maximum edge security.
Core Engineering Advantages
TT9080 High-Toughness PVD
Shock-resistant carbide substrate paired with smooth nano-PVD coating absorbs mechanical impact during interrupted cuts.
EM Exotic-Alloy Chipbreaker
Sharp positive cutting edge with a reinforced land shears sticky stainless chips cleanly without work-hardening the component.
35° Acute Profiling Access
Slender rhombic geometry clears steep shoulders, narrow relief grooves, and complex contours inaccessible to 55° or 80° inserts.

Industrial Applications
- Interrupted Stainless Steel Profiling: Absorbing mechanical impact on stepped shafts with keyways, cross-holes, and uneven forgings in 304/316 stainless.
- Superalloy & Forged Contour Turning: Multi-directional OD copy turning on Inconel, titanium, and heat-resistant aerospace alloys.
- Undercutting & Relief Grooves: Slender 35° rhombic geometry accesses steep shoulders and tight back-angles cleanly.

Frequently Asked Questions
Q: When should I choose TT9080 over TT9215 for stainless steel turning?
A: Choose TT9080 when your operation involves interrupted cuts, scale, or unstable setups where a high-speed grade like TT9215 might experience chipping. TT9080 provides superior substrate toughness.
Q: What does the "EM" chipbreaker stand for on TaeguTec inserts?
A: "EM" designates Medium machining in Stainless Steel and Exotic/Superalloys. It combines a sharp cutting edge with a supportive land to shear gummy alloys cleanly without work hardening.
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).
