Deep HoleSolid Carbide Drill With Max 30D Double Guide Belt Metal Drill Bit

Deep Hole Solid Carbide Drills with Max 30D Double Guide Belt for More Reliable Guidance

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 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.
• 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.

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.
