Product Description:
A high-performance 3 × D solid carbide drill with internal cooling channels, designed for universal applications in aluminum, steel, stainless steel, and other alloys. The internal coolant delivers high-pressure fluid 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:

• 3 × D drilling depth → suitable for medium-depth precision holes.

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

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

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

• High-speed cutting capability → ideal for CNC machining of various metals.

• Universal application → suitable for aluminum, steel, stainless steel, and alloys.
