China 30XD Extra Long Drill Suppliers

In metal cutting, hole processing is the most common process. In hole processing, drill drilling is the basic process.

When drilling, if the hole on the workpiece is very deep, carbide Deep Hole drills should be used at this time.

Specially used for processing deep hole drills, deep hole drills. In processing, holes with an aperture ratio greater than 6 are usually called deep holes. Due to the poor rigidity of the drill rod, it is difficult to remove heat and debris during deep hole drilling, and it is easy to bend and vibrate. Cooling and cooling systems are usually used to solve cooling and chip removal problems. In the automotive, mold and aerospace industries, deep hole drill bits are very popular.
