TaeguTec CNMG190612RT TT5100
Master of Heavy Cast Iron: Large-Format CVD Grade for Aggressive Roughing
Product Overview
"Which extra-large insert is most capable of high-speed roughing in abrasive gray iron without suffering from premature flank wear?"
The TaeguTec CNMG190612RT TT5100 is an industrial-strength solution purpose-built for ISO K (Cast Iron). Utilizing the advanced TT5100 CVD coating, this insert features a thick, heat-resistant alumina layer that thrives in the abrasive environment of gray and nodular iron. The RT (Roughing-Tough) chipbreaker is specifically engineered with a reinforced land and high-stability geometry, making it the premier choice for large-scale roughing where productivity and edge reliability are paramount.
Key Features
Thick-layered coating technology provides maximum abrasive wear resistance for gray iron turning at extreme speeds.
A reinforced edge design that withstands the mechanical shocks of rough surfaces and heavy interruptions in large castings.
The 19.05mm IC size offers superior heat dissipation and mechanical strength for high-torque CNC lathe operations.

Compatible Heavy-Duty Toolholders
This massive 19.05mm IC insert requires high-rigidity external holders such as DCLNR/L 19, PCLNR/L 19, or MCLNR/L 19 series for maximum stability.
Product Applications
- Heavy roughing of large-diameter automotive engine components.
- Machining of heavy industrial pump housings and large valves.
- First-stage turning of nodular iron castings for mining and agricultural equipment.
- High-torque removal on large scale gray iron flywheels and rotors.
TaeguTec Grade Comparison (Cast Iron Focus)
| Grade Name | Main Benefit | Best Use Case |
|---|---|---|
| TT5100 (CVD) | Extreme Wear Resist | High Speed: Gray Iron continuous roughing. |
| TT5080 (PVD) | High Impact Toughness | Heavy Interruptions: Low speeds, rough surfaces. |

Verified Global Feedback
"Gray Iron Monster"
Roughing huge gray iron housings used to kill our tools in minutes. The TT5100 grade at high Vc speeds is unbeatable.
— Heavy Industrial Works (USA)"Stable on Ductile"
Outstanding performance on ductile iron gear boxes. The RT geometry keeps the cut stable even when the surface scale is heavy.
— Machinery Fabrik GmbH (Germany)"Consistent Quality"
Very predictable wear life on long runs. Makes our production planning much easier in a high-volume shop.
— Precision Foundry (Japan)Frequently Asked Questions
1. Is dry or wet machining better for TT5100?
Cast iron is traditionally machined dry to prevent thermal shock and dust slurry. TT5100 is specifically designed to excel in high-heat dry environments.
2. How does the RT breaker handle interruptions?
The RT (Roughing-Tough) breaker features a specialized T-land that reinforces the cutting edge against the mechanical shocks of scale and interrupted cuts.

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.
