Scmt120408 Mrt2 Mr2500P

What is the SCMT120408 MRT2 MR2500P Insert?

The SCMT120408 MRT2 MR2500P insert refers to a carbide turning insert designed for use in CNC (Computer Numerical Control) turning machines. The alphanumeric code gives us valuable information about the insert’s size, shape, material, and coating.

• SCMT: This part of the code refers to the insert’s shape. "SCMT" stands for square inserts with a positive cutting edge, commonly used for turning operations.
• 120408: This is the size of the insert. The first three digits (120) indicate the insert’s width in 1/8 inch increments, meaning 1.20 inches. The last three digits (408) represent the insert's thickness, in this case, 0.08 inches.
• MRT2: This refers to the specific insert grade or series, which indicates the material composition, coatings, and specific cutting characteristics of the insert.
• MR2500P: The MR2500 part refers to the material grade of the insert, while P typically denotes that the insert is designed for precision turning or general-purpose applications, including machining ferrous metals, stainless steel, and alloy steels.

Key Features of SCMT120408 MRT2 MR2500P Inserts

1. Insert Geometry:

   • Shape: Square with a positive cutting edge geometry, ideal for smooth cutting and producing high-quality surface finishes.
   • Chip Control: The insert’s design features chip breakers or relief angles, which help manage chip flow during cutting and reduce the likelihood of chip build-up or clogging.

2. Material:

   • Carbide Composition: Carbide (typically tungsten carbide) is the primary material used in these inserts. Carbide provides excellent hardness, wear resistance, and heat resistance, making it suitable for high-speed cutting operations.
   • Coating: The MRT2 designation likely refers to a coating or treatment that enhances wear resistance, heat resistance, and cutting performance. Coatings such as TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), or CVD (Chemical Vapor Deposition) coatings are commonly used on carbide inserts to improve their performance.

3. Precision and Surface Finish:

   • Designed for precise, high-quality cuts, these inserts produce smooth finishes, reduce tool wear, and maintain high tolerance accuracy. This makes them ideal for machining parts that require exact specifications, such as in the aerospace, automotive, and medical industries.

4. High-Temperature Resistance:

   • Carbide inserts like the MR2500P grade are engineered to withstand the extreme heat generated during high-speed cutting operations. This resistance to heat allows for longer tool life and better cutting performance in demanding conditions.

Benefits of SCMT120408 MRT2 MR2500P Inserts
