TaeguTec WNMG060408EM TT9080 Inserts
Double-Sided 6-Edge Trigon Turning | High-Toughness TT9080 PVD Grade | Box of 10 Pcs
"Which double-sided carbide insert is best for medium turning in stainless steel and tough alloys?"
The TaeguTec WNMG060408EM TT9080 is an economical, heavy-duty negative trigon turning insert engineered to deliver six indexable cutting edges per insert without sacrificing edge strength. Powered by TaeguTec's flagship TT9080 PVD coating grade, this insert combines an ultra-tough sub-micron carbide substrate with a heat-resistant nano-PVD TiAlN layer. It excels in interrupted cuts, scale removal, and gummy materials by preventing micro-chipping, thermal cracking, and Built-Up Edge (BUE). The specialized EM chipbreaker geometry features a reinforced land and positive rake trough that smoothly curls and evacuates chips across medium turning operations in austenitic stainless steel (304/316), Inconel, titanium, and alloy steels.
Core Engineering Advantages
6 Economical Cutting Edges
Double-sided 80° trigon profile provides 6 usable corners per insert, lowering cost-per-edge by up to 33% over CNMG styles.
TT9080 High-Toughness PVD
Ultra-fine grain substrate coated with smooth nano-TiAlN resists mechanical shock, notch wear, and thermal deformation.
EM Medium Chipbreaker
Engineered specifically for stainless steel and superalloys to reduce cutting forces and prevent stringy chip entanglement.

Compatible Tooling Systems
Pair these inserts with standard 06-size (3/8" IC) negative trigon turning holders such as MWLNR/L, DWLNR/L, or PWLNR/L external holders and S-MWLNR/L internal boring bars.
Industrial Applications
- External OD Turning & Facing: High-efficiency stock removal and profiling on CNC lathes and turning centers.
- Internal Boring Operations: Rigid 80° corner angle provides stability during medium-duty bore enlargement.
- Interrupted & Forged Surface Turning: High-toughness TT9080 substrate absorbs impact on castings, keyways, and cross-holes.
System Compatibility
The WNMG 060408EM (ANSI WNMG 332 EM) fits all standard ISO-compliant 80° trigon toolholders featuring a 9.525mm (3/8") inscribed circle pocket, including lever-lock (P-type), wedge-clamp (M-type), and double-clamp (D-type) turning systems.

Frequently Asked Questions
Q: What is the difference between WNMG060408 and WNMG080408?
A: WNMG060408 (ANSI WNMG332) has a 9.525mm (3/8") inscribed circle, making it more compact for smaller boring bars and medium-duty holders. WNMG080408 (ANSI WNMG432) has a larger 12.7mm (1/2") inscribed circle for heavier roughing depths.
Q: What does the "EM" chipbreaker signify on TaeguTec inserts?
A: "EM" stands for Medium machining in Stainless Steel and Exotic/Superalloys. It features a sharp cutting edge with a strong land to prevent work hardening while breaking tough, stringy chips.
Q: How many inserts are included in one box?
A: Each factory-sealed box contains 10 original TaeguTec WNMG060408EM TT9080 inserts (60 total cutting edges per box).

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
