Benefits of Precision Ground Tungsten Carbide Rods

Introduction

Precision ground tungsten carbide rods are essential raw material for manufacturing drills, end mills, punches, and wear components. Their dimensional accuracy and surface quality directly affect final tool performance.

Tight Tolerances

Precision ground rods are held to diameter tolerances of plus or minus 0.005 millimeters and straightness of 0.002 millimeters per 100 millimeters. This reduces grinding time for tool makers and ensures consistent performance.

Surface Finish

Ground rods achieve surface finishes around Ra 0.2 to 0.4, while h6 tolerance ground rods may reach Ra 0.1. Smooth surfaces improve chip flow and reduce built-up edge in cutting applications.

Available Grades

Carbide rods are available in fine-grain grades for finishing tools, medium-grain for general machining, and coarse-grain for heavy-duty interrupted cuts. Blank rods and preformed rods with coolant holes are also available.

Applications

These rods are used to make solid carbide drills, end mills, reamers, punches, pin gauges, and wear pins. They serve aerospace, automotive, mold making, and general machining industries.

Custom Options

Beyond standard diameters, manufacturers can supply rods with coolant through holes, in various lengths, or as custom preforms. This reduces final machining cost for specialized tooling.

Conclusion

Precision ground carbide rods deliver consistent quality and reduce downstream processing. Choosing the right grade and tolerance is essential for optimal tool performance.
