Solid Carbide Flat Bottom Drills for the Bottom Surface Requires a Shallow Hole In the Plane

Applicable Materials:

• All kinds of metal materials

Application:

• Holes with uneven inlet surfaces (including incomplete cuts, bevels, and circular faces).
• Thin-walled holes in hollow shaft parts.
• The bottom surface requires a shallow hole in the plane.

Feature Advantage:

• 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.
• Customized sizes according to customer requirements.

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, 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.
