TaeguTec DCMT11T308FG TT8115
High-Efficiency CVD Gold Grade: Optimized for Abrasive Material Finishing
Product Overview
"Which turning insert offers the best wear resistance for high-speed finishing in Gray and Ductile Cast Iron?"
The TaeguTec DCMT11T308FG TT8115 is a specialized solution for ISO K (Cast Iron) and stable ISO P (Steel). The TT8115 grade utilizes a thick CVD coating with a multi-layered alumina (Al2O3) structure, providing a formidable barrier against heat and abrasive wear. The FG (Finishing-General) chipbreaker is ground to a high-precision sharp edge, which significantly reduces cutting forces and eliminates surface scratching. With a reinforced 0.8mm corner radius, this insert balances elite surface finish with the edge strength required for continuous high-speed CNC turning.
Key Features
Thick CVD Al2O3 coating allows for maximum spindle speeds while protecting the carbide substrate from cratering.
Ground chipbreaker design ensures stable chip breaking at low depths of cut, even in materials prone to stringing.
Superior resistance to plastic deformation, ensuring dimensional accuracy throughout the tool's entire lifespan.

Global Industry Feedback
"Reliable for High Speeds"
We increased our spindle speed by 15% on our cast iron batch. The TT8115 grade didn't flinch—excellent tool life.
— CastPro Precision (USA)"Top Oberflächengüte"
Consistent wear patterns and very clean cuts. The 0.8mm radius gives great strength for high-volume jobs.
— Zerspanung Profis (Germany)"Solid Cast Iron Finishing"
The FG breaker produces perfect chips. No vibration issues at all during long finishing passes.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Is CVD coating better than PVD for Cast Iron?
Yes. CVD coatings like TT8115 are thicker and offer significantly better thermal resistance, which is critical for handling the abrasive nature of cast iron at high speeds.
2. Can I use this for Stainless Steel?
No. For stainless steel, we recommend PVD-coated grades like TT5080. CVD grades can be too brittle for the gummy nature of 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.
