HSS round turning tool steel bars are special-purpose tool steel bars used for making tool parts with high straightness and diameter tolerance. We monitor every steel bar, optimizing it to work at its most stable and ensuring optimal cutting results in machining with lower scattering.
Key Product Features:
Round Tool Steel The straightness control of each round turning tool steel bar is given a strict tolerance standard, and the required tolerance standard can be made into further processing. By using the CNC precision machining and optimizing production processes, it is possible to effectively reduce radial runout during machining, thus greatly improving boring stability and accuracy. Such precise direct high straightness and low diameter pass ingredients are indispensable for ensuring high quality machining results.
By controlling the dimensions to be exactly on target, the diameter tolerance of each steel bar is controlled within h6, providing high stability and accuracy in machining. This makes the steel bars compatible with high-precision equipment, providing greater machining performance, whether in cutting, grinding or other precision processes, always with more success.
Our special heat treatment process gives the toughness and wear resistance needed for effective operation, specifically optimizing the HSS heat-treated steel bars to enhance the durability and cutting capacity. We have heat treated the steel bars in order for it to offer excellent high temperature and heavy load performance, and providing the tool with a longer service life.
HSS round turning tool steel bars can be used to manufacture Drill bits, End mills, Face mills, and Chamfering tools. They provide ideal cutting ability in different machining surroundings. These steel bars allow manufacturing efficient high-precision tools, increasing production efficiency and extending tool lifetime.

We add hardness, wear resistance, red hardness and make the material more rugged giving it the ability to withstand extreme machining conditions through our optimized heat treatment process.
Heat Treatment Process:
Dependable Hardening：The heat treatment (hardening and tempering) process is fully monitored to provide premium hardness that greatly increases the tool wear resistance and durability of the tool in heavy-duty/ high-temperature machining.
Stress Relieval: The process is meant to relieve internal stresses so that the steel is not bent and distorted when machined, which is vital in applications with carefully engineered tolerance requirements.

Benefits of Heat-Treated HSS Round Turning Tool Steel Bars:
Stress relieving after hardening enhances the toughness of these tool steel bars, which accordingly make tools more durable and able to withstand high-speed cutting conditions for a long time.
The heat treatment process increases the HDH steel’s capacity to withstand elevated temperatures while still retaining sharp cutting edges, thus making it well-suited for high-performance cutting tools used in power tools, as well as heavy-duty and high-stress machining applications.
Thanks to the superior wear resistance and red hardness of heat-treated HSS round turning tool steel bars, customers can enhance the durability of their tools and decrease the frequency of replacements leading to reduced production costs.
Each round turning tool steel bar is high-tolerance controlled in straightness and diameter jump to ≤0.1mm by turning, minimizing the runout in the radial direction during machining and significantly improving the cutting performance.

(1)Projector Precise measurement:
This is an experimental system based on precise projection technology, the shape and curvature of the steel bar can be clearly displayed on the screen, which is conducive to the judgment of straightness. Due to the high straightness tolerance requirement of the steel bar, it can immediately show that the bending or deviation on the projector. Both straightness tolerance is rigorously maintained to hold the bars in the most ideal alignment at all sets and to minimization of radial run out to the best possible degree for ensuring structure stability during cutting operations. Furthermore, the tolerance for jump (diameter) can be controlled as low as ≤0.1mm, which greatly increases the homogeneity&quality of end product. This detailed measuring, cutting, heat treatment and entering process cannot be found in standard blank bars which are processed only through grinding with blasting are guaranteed to produce top precision for steel bar for precision machining.
