Product Description

Solid Carbide Drills for Stainless Steel Drilling with Inner Cooling

 

 

The First Choice for Stainless Steel Drilling.

 

 

Feature Advantage:

  • The first choice for mild steel and stainless steel drilling.
  • The sharp cutting edge avoids the formation of built-up edge and is suitable for high performance drilling.
  • The optimized drill tip structure enhances the strength of the chisel and inner edges, makes the cutting lighter and the chip breaking is better.
  • Nano-TiAlN coating for excellent wear and high temperature resistance.
  • The unique groove structure has large effective chip space, smooth chip removal and stable drilling.
  • D3.0-D20.0 diameter
  • The length includes 3D and 5D.
  • Each model has two types: internal cooling and external cooling.

 

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.
