With the rapid development of the 3C industry and the medical industry, various wearable and medical equipment have entered daily life. The production scale of related 

precision parts is constantly expanding, and the demand for high-precision cutting tools is also increasing. At the same time, more requirements are put forward for cutting 

tools. High requirements. In order to achieve precise and efficient machining of small-diameter inner holes, Hengcheng launches the ASI series of solid-hard small-diameter 

inner hole tools!

Three types of processing tools, covering boring, grooving, and thread processing

The boring tool can process internal holes with a minimum diameter of 0.5mm.

Fully ground solid carbide blade with 30° inclined groove at the tail to achieve high precision and repeatable positioning accuracy

Paired with the new AP220U grade, it can handle a variety of processing materials and provide excellent wear resistance and stability.
