TaeguTec TDJ 4 TT9080
Heavy-Duty 4.0mm Universal Insert for Reliable Parting & Deep Grooving
Product Overview
"Which 4mm parting insert provides the highest reliability for interrupted cuts on large diameter steel bars?"
The TaeguTec TDJ 4 TT9080 is engineered for machinists who demand zero-failure performance. When dealing with large diameters or interrupted surfaces (like hex or square stock), the tool faces significant mechanical shock. The TT9080 grade features a specialized sub-micron PVD-coated substrate that excels in absorbing these impacts while maintaining a sharp cutting edge. The TDJ chipbreaker is designed with a high-positive rake that narrows the chip width, ensuring that the 4.0mm chips do not weld to the groove side-walls, even during deep radial operations in Stainless Steel and Alloy Steel.
Core Advantages
TT9080 is a multi-material grade that maximizes tool life in Steel, Stainless, and Cast Iron, streamlining your inventory.
The tough substrate prevents premature edge chipping, making it the safest choice for unstable setups or rough surfaces.
The 4.0mm neutral geometry ensures balanced cutting forces, reducing chatter and improving surface finish on large parts.

"The TT9080 is the only grade that doesn't explode when we part off 4140 hex bar. Rock solid."
— Mike R., USA"Hervorragende Standzeit bei Edelstahl. Die Spankontrolle bei 4mm ist perfekt."
— Dieter K., Germany"Ottima affidabilità. Usiamo questo inserto per tutta la nostra produzione di alberi in acciaio."
— Stefano V., Italy"Very stable in deep grooving. Reduced our tool breakage costs significantly."
— Kenji Y., Japan"Universal indeed. Works on everything we throw at it. Excellent value."
— Arthur P., UKFrequently Asked Questions
A: While it can cut Aluminum, the TT9080 grade is PVD coated for toughness in harder metals. For Aluminum, we recommend the K10 uncoated grade for a sharper edge and zero material welding.
A: No. The TDJ series is specifically for radial grooving and parting. For turning and grooving, consider the TDC or TDT series.
A: Yes, as a neutral (0°) insert, it will leave a small center pip. For a flat-face finish on the part, you would need a lead-angle version (e.g., 6R/15R).

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.
