Product Description

Solid Carbide Drills with Multi Series Selection for All Types of Material Drilling

 

 

 

Feature Advantage:

  • It includes general processing series, stainless steel special series, high temperature alloy special series, deep hole drilling series, etc. A variety of series options, can achieve efficient processing of steel, stainless steel, cast iron, aluminum alloy, high temperature alloy and other materials.
  • Optimized drill tip structure for better cutting performance and improved machining stability.
  • ∅ 2 - ∅ 25 Diameter, complete types.
  • 3D, 5D, 8D, 12D, etc., all kinds of lengths are complete.
  • All types are available in both internal and external cooling to meet the requirements of various machine tools.
  • The coating combines excellent wear resistance and anti-blocking properties to improve edge stability.
  • The unique coating post-treatment technology effectively reduces the cutting force, making the chip removal smoother and safer.

 

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.
