Boring Heads & Boring Tools

What is a lathe boring head?

A lathe boring head is a tool used in machine tools such as lathes and milling machines. It is designed for boring — enlarging existing holes — and for performing precision internal machining operations. The boring head consists of a robust body fitted with cutting tools, which can be adjusted manually or automatically depending on the model. It also features a shank that allows secure mounting in the spindle of a lathe or milling machine.

Applications and functions of a milling boring head

Boring heads, especially those with automatic feed, offer advanced machining capabilities, including:

• Boring holes of various diameters – allowing adaptation to different design and material requirements, increasing versatility; precise diameter adjustment ensures high-quality finishing of every hole;

• Facing internal surfaces – produces perfectly smooth and even faces, crucial for high-precision applications and tight dimensional tolerances in machine part production;

• Turning external surfaces – ensures a smooth and uniform external finish, important for both aesthetic and functional reasons; accurate turning removes surface irregularities and imperfections;

• Cutting grooves and threading – enables the creation of connecting elements, improving tool versatility; precise thread cutting ensures durable and reliable joints;

• Multi-tool machining of internal and external surfaces – allows simultaneous use of multiple cutters, significantly speeding up production and increasing efficiency; particularly useful in serial manufacturing where speed and repeatability are essential.

Thanks to their versatility, boring heads enable a wide range of advanced machining operations. Beyond basic boring and facing, advanced models also allow multi-tool machining and precision threading. These tools are indispensable in workshops requiring high accuracy and flexibility. High-quality boring heads are a valuable investment, ensuring long-term reliability and productivity.

Universal boring heads in our range

At CORMAK, you will find universal boring heads designed to perform a variety of complex operations. Our boring heads are equipped with an automatic feed mechanism, ensuring precision while reducing machining time.

Our automatic boring heads are available in several sets, such as MK3, MK4, ISO40. Each set includes:
