Product introduction

A carbide single straight hole round bar is a kind of carbide bar made by powder metallurgy technology, which has the characteristics of high strength, high hardness, good wear resistance, and bending strength. Its manufacturing process mainly includes mixed powder preparation, pressing, sintering, and processing steps, single straight-hole round rod is mainly used for manufacturing high-precision, high-hardness tools, tools, measuring tools, wear-resistant parts, and structural parts. For example, it can be made into various specifications of drills, tools, and sealing rings through secondary processing to meet the needs of different fields.
