Solid carbide deep hole drill is an effective deep hole machining tool, which is widely used in metal machining, and can be used for metal cutting,  like: aluminum, steel, cast iron, cast iron, and copper, Brass, stainless steel and other materials. In metal machining, the hole with a ratio of hole depth to hole diameter greater than 6 is usually called a deep hole.  When drilling deep holes, heat dissipation and chip removal are the two main problems, so the pressure cooling system is generally used to solve the cooling and chip removal problems.

Generally speaking, carbide deep hole drills are equipped with internal cooling holes. The coolant oil has two functions, one is to cool down, because a lot of heat is generated during the processing process, and the other is to punch out the chips in the hole,In case the drill bit will be broken.
