What is Stock?

In this context, Stock refers to the German company R. Stock AG, which manufactures rotary cutting tools for metalworking. The company specializes in rotationally symmetric precision tools mainly used for drilling, threading, and milling applications in the machining industry. Stock operates as part of a larger group of companies in the tooling industry and leverages in-house research and development, as well as proprietary carbide materials and coating production.

Stock and Rotary Cutting Tools in Machining

Stock’s core expertise lies in rotary cutting tools such as twist drills, taps, milling cutters, reamers, and counterbores. These tools are made from a variety of materials including HSS, HSCo, and different carbide grades, as well as cermet and PCD solutions.

Stock’s Special Tools and Custom Solutions

In addition to standard tools, Stock manufactures custom special tools tailored to individual customer needs. These are especially useful when a machine shop wants to combine multiple operations into a single tool or optimize the process for a specific component.

In designing special tools, factors such as the material being machined, machining method, available machinery, and desired tolerance and surface roughness are taken into account. This application-specific approach supports efficient machining processes and can reduce tool changes and shorten lead times in the machine shop.

Stock’s Services and Tool Lifecycle Management

Stock offers a range of services related to their tools, including regrinding and recoating. These services help the machine shop extend tool life and manage costs more effectively. In addition, the company provides technical field service, supporting customers from tool selection through to the development of overall tool management processes.

In practice, this means machinists receive support in determining the correct cutting data, tool optimization, and process stabilization. Application support is an important part of the total solution, especially when working with demanding materials or tight tolerances.

Stock in the Global Machining Industry

Stock’s products are distributed widely to various markets and are used in industries such as automotive, machine engineering, mold and tool making, and aerospace applications. An extensive distribution network ensures technical support and product availability across many industrial sectors.

Within the machining industry, Stock is especially known for its drilling and threading tools, which combine precision, repeatability, and compatibility with automated CNC production.

Summary

Stock, or R. Stock AG, is a German manufacturer of rotary cutting tools, offering a range that includes drills, taps, milling cutters, and other precision tools.
