Product Description

Solid Carbide Drill for 9D Deep Hole Stainless Steel With Internal Cooling High Precision

 

 

Technical Information:

  • The special drill point structure optimized for deep hole drilling can process deep holes up to 9 times the drill diameter.
    Sharp cutting edge, smooth chip removal, light cutting, effectively improve the surface quality of the machined hole.
    Excellent special coating and cutting edge treatment technology significantly increase the service life of the drill.

 

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.The recommended cutting parameters are externally cooled drills, Internally cooled drills can be increased by 10%-15% depending on the situation.
