Double Edged Belt Tungsten Carbide Drill Bit Set For 8D Deep Hole Drilling

Solid Carbide Drills with Double Edged Belt for 8D Deep Hole Drilling

Feature Advantage:

• This series of solid carbide drills is extremely versatile, and the same series can achieve efficient drilling of steel, stainless steel, cast iron and other materials.
• Optimized drill tip structure for better cutting performance.
• Double-edged belt design for improved drilling stability.
• ∅2 - ∅25 Diameter, 0.1 mm first gear, complete types.
• 3D, 5D, 8D, all kinds of lengths are complete.
• All specifications and models are available in both internal and external cooling to meet the requirements of various machine tools.
• AlCrN coating combines excellent wear resistance with anti-blocking properties for improved edge stability.
• The unique coating post-treatment technology effectively reduces the cutting force, making the chip removal smoother and safer.

Technical Information:

• Typical application of solid carbide drills:
  • 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, tool geometry selection, coolant pressure, capacity, and cutting parameters.
• Chip clogging can cause the drill to move radially and affect hole quality, tool life and reliability.
• The drill 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, Internally cooled drills can be increased by 10%-15% depending on the situation.
