Tool materail: Considering wear resistance and impact resistance, ultra-fine tungsten carbide materials with reasonable hardness and toughness are used to ensure the durability of carbide taps
Geometry: To increase rigidity and prevent edge breakage, special rake angles are designed
Chamfer length: Considering stability and toollife, the length of the cut in chamfer is usually 4-5 teeth
Machine: Suggest to use a machine tool with low vibration and the ability to choose a reasonable feed rate to achieve stable tapping
Bottom hole: Drill the bottom hole as large as possible within thread tolerance because it helps reduce the torque load and tapping becomes longer life.

OPT TOOLS offering of fully stocked solid carbide boring bars, all of which are CNC grounded, also fast delivery in customization orders.

Advantages:

  • Advanced edge preparation technologies enhance the performance and tool life
  • Helical back rake flute improves accuracy and chip flow and improve rigidity
  • Tip is grounded to sharp corner
  • CNC grounded ensure uniform microgeometry
Coated MTR carbide boring bar
  • Familiy tools

Inspection and display

Before ordering, please communicate with our pre-sales customer service:
1. Workpiece material
2. Whether product is surface treated after processing
