TaeguTec TCMT110208MT TT8020
Engineered for Toughness: Maximum Edge Strength for Stainless Steel and Interrupted Cuts
Product Overview
"Increase your feed rates in difficult materials with the reinforced 0.8mm corner and the impact-resistant TT8020 substrate."
The TaeguTec TCMT110208MT TT8020 is a versatile 11mm triangular turning insert optimized for Stainless Steel (ISO M) and Low-Carbon Steels. This configuration is specifically designed for machinists who need more durability than a standard finishing insert. The 0.8mm corner radius significantly strengthens the cutting edge, making it highly resistant to chipping during interrupted cuts or when machining parts with scale. The TT8020 PVD-coated grade provides excellent resistance to built-up edge (BUE) and thermal shock, ensuring reliable performance in both wet and dry machining environments. Featuring the MT (Medium Turning) chipbreaker, this insert maintains superior chip control even at varying depths of cut.
Core Advantages
A sub-micron PVD grade that excels in toughness, preventing premature breakage in unstable setups or heavy interruptions.
The larger radius allows for higher feed rates (fn) and provides a more robust edge for machining tougher alloy and stainless steels.
Designed with a positive rake angle to reduce cutting forces and minimize work-hardening of the stainless steel workpiece surface.

Frequently Asked Questions
1. Should I use the 0.8mm radius instead of the 0.4mm?
Choose the 0.8mm radius (this model) if you are experiencing edge chipping or if you want to increase your feed rates. Use the 0.4mm radius for very fine finishing or if the part is thin-walled and prone to vibration.
2. How does TT8020 handle work-hardening?
TT8020 is engineered with a sharp, positive MT geometry. This allows the tool to slice through the material rather than rubbing it, which is the primary cause of work-hardening in stainless steel.

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.
