What are the superior performance of deep hole drills?

 With the development of the processing industry, honing machines are also widely used in the industry, and honing technology has also been recognized by the industry.

So what are the superior performances of the deep hole drill as one of the honing machines?

Deep hole drills using high-quality deep hole drill products are divided into external chip removal and internal chip removal according to the chip removal method. The external chip removal has gun drills and integral alloy deep hole drills (which can be divided into cooling holes and no cooling holes. The internal chip removal is divided into three types: BTA deep hole drilling, jet suction drilling and DF system deep hole drilling. Deep hole drills combine the flexibility of high-speed steel drills with the long life of solid carbide drills. The advantage of this deep hole drill is that it is not easy to break due to positioning errors during drilling.

This advantage is based on a new type of cemented carbide and unique geometric shapes. The drill bit is designed with a flexible drill rod, which enables the drill bit to withstand the bending deformation far exceeding the solid carbide drill bit. This flexibility makes deep hole drilling with small diameter tools simple and easy.
