Product Details

Solid Carbide Drills with Straight Groove for ISO K N Cast Iron / Excellent Self Centering Capability

 

 

  • The First Choice for Precision Hole Drilling in Cast Iron.

 

 

Feature Advantage:

  • Non-coated.
  • Suitable for short chip materials such as cast iron and silicon aluminum alloy.
  • Excellent self-centering capability for efficient machining and machining of workpieces with hole machining accuracy of H7.
  • The machined holes achieve high position, straightness and surface quality.
  • Optimized drill tip structure for better cutting performance.
  • ∅4 - ∅25 Diameter, complete types.
  • 5D, 15D, all kinds of lengths are complete.
  • All types are available in both internal and external cooling to meet the requirements of various machine tools.

 

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.
