Internal profiles
These internal broaches are used in advanced industries such as precision engineering, aerospace, automotive and manufacturing, where precise internal fits are essential for the proper functioning of gears, shafts and other critical components. Used on CNC lathes and automated machining centres, they ensure consistent performance and dimensional repeatability even during high-speed machining. Engineers and professionals choose these tools for their reliability, wear resistance and versatility, making them an indispensable element in optimising production processes and improving the efficiency of internal broaching operations. The most common internal profiles used in broaching are square profile broaches, which are used to hold bars or handles and levers with square shanks. Internal hexagon broaches are typically used to create an internal hexagon on threaded screws, valves and inserts, where the internal shape allows actuation using Allen keys. A final common internal profile is the Torx profile, which is widely used in the automotive, medical and aerospace sectors, and is increasingly found in many other industrial applications. The Torx shape is created on threaded components such as screws, valves and inserts, where the internal geometry allows tightening and releasing with specific Torx wrenches, facilitating assembly and maintenance in various mechanical assemblies.
