Carbide Rods

As a specialist in cemented carbide, Nihon Hard Metal Co., Ltd is always striving for the manufacture of high-quality and high-value-added products, quick delivery, development of new products and the reduction of total costs to meet market needs.

Straight Rods

There are two types of straight rods: Solid and with Holes.

Our straight rod material is used in a wide range of applications, such as drills, taps, end mills, reamers, etc. To maximize the capacity of cutting tools, we provide a large number of products suitable for tool configuration, coating and work materials.

Twisted Coolant Hole Rods

There are two types of spiral oil holes: 2-holes and 3-holes.  

The material with oil holes for cooling requires a hole that must be precisely located and whose helix angle must be precisely determined to prevent hole breakdown during groove processing. The variations in manufacture of the helix angle and lead precision of our twisted hole material are very low and the material enjoys a reputation for world-class quality.
