Carbide Insert SPMG (pack of 10 1box)

SPMG specifications refer to the dimensional and performance characteristics of SPMG indexable inserts, commonly used in U-drills for drilling operations. These specifications include the inscribed circle diameter (IC), insert thickness (S), corner radius (RE), coating type, and applicable materials. Different SPMG insert models, like SPMG 060204 or SPMG 140512, will have specific dimensions and performance characteristics tailored for various applications. 

Key SPMG Specifications:

• Inscribed Circle Diameter (IC):

  This refers to the diameter of the inscribed circle within the insert's geometry, influencing the size of the hole that can be drilled. 

  
  

  • Insert Thickness (S):

    The thickness of the insert, affecting its stability and strength during drilling. 

    • Corner Radius (RE):

      The radius of the cutting edge corner, impacting the surface finish and stability of the drilled hole. 

      • Coating:

        Coatings like TiCN or PVD/TiAlN are applied to enhance wear resistance and tool life. 

        • Applicable Materials:

          SPMG inserts are designed for drilling various materials, including steel, stainless steel, and superalloys. 

          • Grade:

            Specific grades (e.g., CT5010) indicate the material composition and suitability for different cutting conditions. 

            • Cutting Width (CW):

              This refers to the width of the cutting edge and is related to the depth of cut. 

              • Hole Diameter (for insert holder):

                This refers to the diameter of the hole in the insert holder where the insert is mounted.
