TaeguTec TCMT16T308MT TT5100
Premium CVD Coated Insert for High-Velocity Cast Iron Turning
Product Overview
"Which insert is best for high-speed machining of abrasive Grey or Ductile Cast Iron?"
The TaeguTec TCMT16T308MT TT5100 is the definitive answer for industrial cast iron applications. This 16mm triangular insert utilizes the TT5100 CVD (Chemical Vapor Deposition) grade, featuring a thick Alumina (Al2O3) layer that acts as a superior thermal shield against the abrasive nature of graphite. The MT (Medium Turning) chipbreaker is engineered with a positive rake angle to shear through brittle materials efficiently, while the 0.8mm corner radius provides the structural integrity required for higher feed rates and long-duration finishing in high-output CNC environments.
Key Features
The TT5100 grade offers extreme wear resistance, specifically designed to combat flank wear in abrasive ISO K materials.
Engineered for high surface footages (Vc), allowing for maximum RPM without compromising the carbide substrate.
A balanced chipbreaker that reduces cutting pressure and prevents vibration in large-diameter workpieces.

"TT5100 is a monster for grey iron. We doubled our Vc from 200 to 400 m/min with no chipping."
— Hans G., Germany"Fast delivery to Tokyo. The MT chipbreaker works great on our ductile iron pulleys."
— Tanaka S., Japan"Solid performance in US job shop. Best cost-per-edge for 16mm inserts."
— Mike R., USA"Ottimo per ghisa. Wear resistance is world-class."
— Luca B., Italy"Standard choice for our CNC production lines. Highly reliable."
— David L., USAFrequently Asked Questions
A: While possible, it is not recommended. TT5100 is specifically optimized for Cast Iron. For Steel, we recommend the TT8100 series.
A: MT represents 'Medium Turning'. It provides a balanced geometry that handles both semi-finishing and medium roughing depths efficiently.
A: Yes, as long as the boring bar is designed for TCMT 16T3 (3/8" I.C.) inserts with a 7-degree relief.

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.
