Product Description

WCMT080412 Carbide Drill Inserts for General Drilling with Smooth Cutting

 

 

Technical Information:

  • Typical applications for indexable insert bits:
    • Medium and large diameter holes
    • Medium tolerance requirements
    • Need flat bottom blind hole
    • Drilling or boring
  • Chip formation and chip evacuation are important issues in drilling. It depends on the workpiece material, insert geometry selection, coolant pressure, capacity, and cutting parameters.
  • Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.
  • 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 drilling, for safe production, the insert should be replaced in time when the flank wear and crater wear exceed a certain value.
  • The value of the cooling pressure is very important. If the pressure is too low, it will cause vibration and shorten the life of the insert.
  • Drilling holes using indexable insert bits for high efficiency and economy.

 

Feature Advantage:

  • The use of a triangular insert for optimum centering performance and high precision of the machined hole.
  • Optimized cutting edge design, the cutting process is more stable and the chip breaking is better.
  • 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.
  • The combination of grades and chipbreaker makes all kinds of machining problems easy to solve.
  • High toughness ultra-fine cemented carbide substrate with good edge strength.

 

  • Grade MP2252:
    • Special coating process makes the surface of the insert smooth, effectively reducing friction and making chip removal smoother.
    • 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 blade.
    • Both the inner and outer edges can meet the physical performance requirements 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 machining efficiency
