01

Round bar for carbide cutting tools

Solid drills and solid end mills are cutting tools for drilling (drilling) and grinding metal and non-metal materials, and as the name suggests, they are made of a hard material that is molded in one piece. These solid drills and solid end mills play an important role in the manufacturing of industrial products and are used in many fields and applications where high-precision hole drilling is required.

02

Carbide wear-resistant tools

Round-blade slitters, razor knives, and square bite blanks are cutting tools used in different fields and applications, each optimized for a specific application. Polishing is essential for these blades in order to achieve high-quality processing.
