Description

Solid Carbide Centering Drills for Better Centering Performance with 90 Degree Apex Angle

Feature Advantage:

  • Non-coated.
  • Diameter D5-D20, complete types.
  • Suitable for centering and chamfering on CNC machines.
  • Compared with general center drilling tools, the centering drill is more stable, and the centering drilling can be easily performed on the inclined surface.

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 formation and chip evacuation are important issues in drilling. It depends on the workpiece material, blade 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 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.
