TaeguTec SOMT060204DP TT8020
Mastering High-Feed Milling: PVD Performance for Stainless and Exotic Alloys
Product Overview
"Which milling insert is the best for high-feed rates in gummy stainless steels while maintaining long tool life and preventing thermal cracks?"
The TaeguTec SOMT060204DP TT8020 is the answer for high-productivity milling. The TT8020 grade features a specialized sub-micron substrate paired with a high-density PVD coating, offering exceptional resistance to built-up edges and oxidation. The DP (General Purpose) chipbreaker is designed with a reinforced cutting edge that allows for aggressive high-feed milling without the risk of catastrophic fracture. Optimized for ISO M (Stainless) and ISO S (Exotics), this insert ensures stable machining even in deep pocketing or long-overhang applications.
Key Features
Optimized for thermal stability and toughness, preventing micro-chipping in materials prone to work-hardening.
The general-purpose DP breaker offers high edge strength, making it perfect for ramping and plunging.
Designed for high metal removal rates (MRR) by directing cutting forces axially toward the spindle.

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.
