SPMG07T308 Carbide Drill Inserts with Two Uses of One Insert and Smooth Cutting

 

 

Technical Information:

  • Typical applications for indexable insert bits:
    • Compared with drills of other structures, the use of indexable insert drills for hole drilling is more efficient and economical.
    • Medium tolerance requirements
    • Medium and large diameter holes
    • Need flat bottom blind hole
    • Insert drilling or boring
  • Cooling pressure values ​​are important, and low pressures can cause vibration and shorten insert life.
  • The two common types of insert wear are flank wear and crater wear.
  • Usually flank wear is a form of natural wear, especially for outer inserts with higher cutting speeds. However, this wear will eventually result in the cutting edge of the insert not being able to machine the required tolerances and high surface quality.
  • For safe production, the insert should be replaced in time when the flank wear and crater wear exceed a certain value.
  • Chip formation and chip removal depend on the workpiece material, insert geometry selection, coolant pressure, capacity, and cutting parameters, which are important issues in drilling.
  • Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.

 

Feature Advantage:

  • High toughness ultra-fine cemented carbide substrate with good edge strength.
  • Optimized cutting edge design, the cutting process is more stable and the chip breaking is better.
  • The combination of grades and chipbreakers makes all kinds of machining problems easy to solve.
  • The same insert can be installed on the center edge and the outer edge, while meeting the requirements of the center and outer edge, economic and efficiency.
  • Square insert, four cutting edges, more economical.

 

  • Grade MP2253:
    • Special coating process makes the surface of the insert smooth, effectively reducing friction and making chip removal smoother.
    • Both the inner and outer edges can meet the physical performance requirements of the insert.
    • Unique nanostructured coating, the coating is more tightly bonded to the substrate, and has higher toughness and hardness.
    • Special surface treatment technology after coating to remove harmful stress and improve the surface quality of the insert.

Recommended Cutting Parameters:

  • The following cutting parameters are the recommended range values, which should be adjusted as appropriate after considering the following factors:
    • Specific physical properties of the material being processed
    • Power and rigidity of the machine tool
    • Clamping rigidity of tools and workpieces
    • Balance between tool life and processing efficiency
