Product Description

Solid Carbide Drills with 20D Double Guide Belt for Deep Hole Drilling

 

 

Suitable for Deep Hole Drilling of Steel, Cast Iron & Other Materials.

 

 

Feature Advantage:

  • The optimization of the tool structure is achieved by cutting simulation analysis.
  • The design of the variable-parameter spiral groove takes into account the rigidity and chip removal performance of the tool.
  • The ultra-fine alloy matrix with good strength, toughness and wear resistance combined with the nanostructured TiAlN coating optimized for drilling ensures the high toughness and strength of the tool.
  • The unique coating process gives the tool a smooth surface and extremely high wear resistance.
  • Outstanding thermal stability and chemical stability provide effective protection for the cutting edge.
  • The unique cutting edge design can show good chip breaking performance and versatility even for viscous materials.
  • Double guide belts for more reliable guidance and more stable machining.
  • Nano-coating with good self-lubricating properties, excellent wear resistance and high temperature resistance.
  • D3.0-D11.60 diameter.
  • The length includes 12D, 20D, 30D.
  • The whole series is cold inside.
  •  

Technical Information:

  • 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.
  • Typical application of integral alloy drill bits:
    • Small diameter hole
    • Tight or precision tolerance hole
    • The hole shorter than a deep hole

 

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.
