TaeguTec CCMT09T308MT TT8020
The Toughest PVD Solution for Interrupted Stainless Steel & HRSA Turning
Product Overview
"Which insert grade provides the maximum edge security for interrupted cuts in 316 stainless steel or when machining parts with uneven surfaces?"
The TaeguTec CCMT09T308MT TT8020 is an 80° rhombic turning insert designed as the "insurance policy" for difficult ISO M (Stainless Steel) and ISO S (Heat Resistant Alloys) operations. While finishing grades often chip during interruptions, the TT8020 PVD coating utilizes a specialized sub-micron substrate with enhanced multi-layer adhesion to absorb mechanical shocks. The MT chipbreaker (Medium Turning) features a reinforced edge geometry that prevents built-up edge (BUE) and ensures stable chip breaking across varying depths of cut, even in gummy materials.
Key Features
A multi-layer PVD coating optimized for impact resistance and high-adhesion strength in stainless alloys.
Medium-Turning design that provides excellent chip control while maintaining high edge stability during shock loads.
Offers increased edge strength and superior surface finish overlap for efficient production cycles.

Why Choose TaeguTec?
TaeguTec, as a member of the IMC Group, is at the forefront of high-performance metallurgy. The TT8020 grade was specifically developed to tackle the most unstable turning environments. While standard carbides crack under mechanical impact, TaeguTec’s multi-layered PVD technology absorbs the shock, keeping your production line running without unexpected tool failure. Choosing TaeguTec means investing in South Korean precision engineering that focuses on reducing your cost-per-part through extreme reliability.
Verified Global Feedback
"Reliable in rough cuts"
We switched to TT8020 for our interrupted stainless shaft turning. It’s the only grade that doesn't chip on the keyway cuts.
— Precision Eng (USA)"Hervorragende Standzeit"
Consistent results in 316Ti. Even with vibration, the edge stays intact. Very impressive toughness.
— Mechanische Werkstatt (Germany)"Ottimo per Inox"
Predictable wear and great chip control. We use it for all our non-stable stainless setups.
— Officina Meccanica (Italy)Frequently Asked Questions
1. Should I use TT8020 for high-speed continuous finishing?
If your setup is stable and the cut is continuous, TT7015 will offer higher wear resistance at higher speeds. Use TT8020 specifically when toughness is needed.
2. Can this be used on Titanium alloys?
Yes. It is an excellent choice for ISO S (Super Alloys) finishing where edge security is paramount.

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.
