TaeguTec TDT 4E-0.4 TT9080
The Universal 4.0mm Solution for Precision Side-Turning, Profiling, and Grooving
Product Overview
"Which 4mm insert is best for multi-directional turning and profiling in alloy steel with interrupted cuts?"
The TaeguTec TDT 4E-0.4 TT9080 is the ultimate "problem solver" for CNC workshops. While standard grooving inserts are limited to radial movement, the TDT series is engineered with a reinforced structure that allows for axial turning (side-turning) and profiling in a single setup. The TT9080 grade features a specialized sub-micron carbide substrate paired with a multi-layered PVD coating, offering incredible toughness. Whether you are dealing with the mechanical shocks of interrupted cuts or the heat of Stainless Steel, the 4E chipbreaker ensures optimal chip compression and evacuation, maintaining a superior surface finish across varying diameters.
Core Advantages
Perform radial grooving, longitudinal turning, and complex profiling with one tool, reducing turret indexing and cycle time.
Superior resistance to edge chipping and thermal cracking. Perfect for tough alloys and unstable machining conditions.
Two precision cutting edges per insert double your tool life and significantly lower your cost-per-part.

Applications & Compatibility
- Profiling & Undercutting: The TDT geometry is optimized for traversing complex contours.
- Interrupted Cuts: The TT9080 grade is the first choice for non-continuous surfaces in steel.
- Multi-Tasking: Ideal for lathes with limited tool stations as one tool does the job of two.
- Tooling System: Fully compatible with all TaeguTec T-Turn series external holders and boring bars with Seat Size 4.

"Perfect for profiling 4140 steel. The TT9080 grade is incredibly tough when hitting keyways."
— James R., USA"Sehr gute Standzeit bei unterbrochenem Schnitt. Absolut zuverlässig."
— Dieter K., Germany"Ottimo inserto per la tornitura laterale. Chips perfetti anche su inox."
— Marco G., Italy"Consistency is great. We ran 500 parts without a tool offset change."
— Tanaka S., JapanFrequently Asked Questions
A: No. TDT inserts are designed for the T-Turn system, which provides the side support required for turning. TDJ holders are strictly for radial parting/grooving.
A: Yes, it is a universal grade. While TT9030 is specialized for Stainless, TT9080 is excellent for general stainless work, especially where the cut is not continuous.
A: For 4.0mm inserts, we recommend a side-turning depth of 0.5mm to 2.0mm depending on material hardness and machine rigidity.

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.
