5D Stainless Steel Solid Carbide Drill with Internal Cooling

Product Description:
A high-performance 5 × D solid carbide drill designed specifically for stainless steel and other hard-to-machine alloys. Equipped with internal cooling channels, this drill delivers high-pressure coolant directly to the cutting edges, ensuring efficient heat dissipation, smooth chip evacuation, and superior hole quality. Optimized cutting geometry and polished flutes provide high-speed cutting capability, stability, and long tool life.

Key Features:

• 5 × D drilling depth → suitable for medium-depth precision holes in stainless steel.

• Solid carbide construction → high rigidity, excellent wear resistance, long service life.

• Internal cooling channels → direct coolant delivery for efficient cooling and chip removal.

• Optimized cutting geometry & polished flutes → smooth chip evacuation, reduced built-up edge.

• High-speed cutting capability → ideal for CNC machining of stainless steel and alloys.

• 
  

Applications:

• Aerospace stainless steel components.

• Automotive engine blocks, cylinder heads, and chassis parts.

• Food processing and medical device stainless steel components.

• Industrial machinery and equipment stainless steel assembly or fluid passage holes

• Parameter table
