internal coolant Carbide Drill Bits for metal materials

The Carbide drill bit is a hole-drilling tool made from tungsten carbide material. They provide the best combination of penetration rate and precision. It can be used in drilling holes out of all kinds of metal materials like steel, aluminum, and bronze along with other non-metal materials like wood, concrete, masonry, tile, and more.


We manufacture and stock carbide drills for different applications. Our standard ones are 3D and 5D carbide drills for general purposes with bronze coating. The drill bits’ substrate material, geometry, and coating can determine their drilling performance in certain materials. And we can manufacture as per your requirements.


The internal coolant carbide drill is always preferred to avoid chip jamming when drilling deeper holes (4-5 × DC),especially in long chipping materials.


Our carbide drill bits are for industrial use in materials such as aluminum, steel, nonferrous heavy metal, and stainless steel.  Carbide drill bits maintain a sharp cutting edge longer than HSS or Cobalt and are run at higher speed rates as they absorb heat more efficiently.


Compared to HSS Drills

Our carbide drill bits are for industrial use in materials such as aluminum, steel, nonferrous heavy metal, and stainless steel.  Carbide drill bits maintain a sharp cutting edge longer than HSS or Cobalt and are run at higher speed rates as they absorb heat more efficiently.

We supply both solid and coolant through carbide drills in a wide range of sizes.  Our coolant drills are standard with AlTiN coating to perform a higher cost per drilled hole.
