TaeguTec RCMT10T300MT TT5100
Mastering Cast Iron: The High-Speed Round Insert for Superior Profiling
Product Overview
"Which round insert grade offers the best heat resistance and edge stability for profiling abrasive ductile iron at high cutting speeds?"
The TaeguTec RCMT10T300MT TT5100 is an industrial-grade solution for ISO K (Cast Iron) turning and profiling. The TT5100 grade is defined by its ultra-thick CVD Alumina coating, which acts as a thermal barrier during the intense friction of high-speed iron machining. The Round (R) geometry provides the strongest possible cutting edge, distributing cutting forces across a larger surface area to prevent chipping. Paired with the MT (Medium) chipbreaker, this insert excels in profiling operations where the depth of cut changes constantly, ensuring stable chip control and exceptional surface Ra values.
Key Features
Specifically optimized for Cast Iron, providing elite resistance to abrasive wear and high-temperature oxidation.
The Medium chipbreaker design ensures smooth chip evacuation during complex profiling and medium-duty turning.
The 10mm round profile allows for high feed rates and varying lead angles, maximizing productivity in CNC workflows.

Compatible Toolholders
This RCMT 10-series insert requires standard round-pocket holders. For heavy profiling in cast iron, we recommend: SRDCN 10 or SRGCR/L 10 series holders.
Product Applications
- Heavy profiling of automotive engine components and brake rotors.
- Turning of industrial gray and ductile iron pump housings.
- High-speed continuous turning where abrasive wear is the primary failure mode.
- Aerospace and wind energy iron casting components requiring stable profiling.

Verified Global Feedback
"Profiling Powerhouse"
We use these for ductile iron pump bodies. The round shape is so much stronger than our previous DNMG inserts. Tool life is up 40%.
— Cast Components Inc. (USA)"Top für Grauguss"
Outstanding performance on gray iron brake discs. The TT5100 coating handles the high-velocity heat perfectly.
— Bremsentechnik GmbH (Germany)"Resistenza Incredibile"
Consistent chip control and excellent finish. The MT geometry works very well on our CNC profiling passes.
— Meccanica di precisione (Italy)"Reliable Tool Life"
A very stable grade. We can run entire shifts without needing to compensate for wear on the machine.
— Sato Heavy Machining (Japan)Frequently Asked Questions
1. Can I use RCMT on Steel (ISO P)?
While it can turn steel, TT5100 is specifically optimized for Cast Iron (ISO K). For steel, TT8115 is a better choice.
2. Why use a round insert instead of a diamond shape?
Round inserts have the highest edge strength. They allow for much higher feed rates and are the best for profiling where the approach angle changes.

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.
