Introduction

A helical coolant holes carbide rod is a type of solid carbide rod that incorporates two helically-shaped coolant holes drilled along its length. These unique coolant holes are designed to optimize coolant flow and chip evacuation during machining operations. By providing improved cooling and efficient chip removal, these rods help to enhance tool life, reduce heat buildup, and improve overall machining performance. They are commonly used in high-speed machining and applications where effective cooling and chip control are critical.

Composition and Structure

Composition: The tungsten carbide particles make up the majority of the composition, providing the rod’s hardness and wear resistance. The binder material, such as cobalt or nickel, acts as a matrix that holds the tungsten carbide particles together.

Structure: The structure of a helical coolant holes carbide rod is typically dense and uniform due to the sintering process used during manufacturing. Sintering involves heating the green compact to a high temperature, allowing the tungsten carbide particles to bond together and form a solid structure. The helical coolant holes are precision-drilled along the length of the rod, creating a spiral pathway for coolant flow.
