Product Description

Solid Carbide Drills for Drilling and Milling Thread Compound Drilling




Feature Advantage:

  • Efficient cutting: threaded bottom hole, hole chamfering and thread milling with one knife.
  • High precision and long life: the thread is bright, the accuracy level is adjustable, the coaxiality is high, and the service life is up to 200m.
  • Unique structure: unique internal cooling structure, central internal cooling plus blade partial flow.


Technical Information:

  • Typical application of integral alloy drill bits:
    • Small diameter hole
    • Tight or precision tolerance hole
    • The hole shorter than a deep hole
  • Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.
  • Chip formation and chip evacuation are important issues in drilling. It depends on the workpiece material, blade geometry selection, coolant pressure, capacity, and cutting parameters.
  • The drill bit is mounted on the shank chuck and its circumferential runout must be less than 0.02 mm.


Recommended Cutting Parameters:

  • When using this series of tools for the first time, the cutting is performed according to the recommended cutting speed of 90% or the feed rate of 85%. When the cutting condition is stable, the cutting speed and the feed are increased one by one.
  • Cutting parameters are recommended for water soluble cutting fluids.
  • Use a defect-free, clean chuck when installing the drill and control the drill runout to within 0.02 mm.
  • The recommended cutting parameters are for applications where the hole depth is below 5D.
  • The recommended cutting parameters are externally cooled drills, which can be increased by 10%-15% depending on the situation.
