The success of unibor broaching (or annular) cutters is proven in their daily use in many kinds of application throughout the world.

By removing only the metal at the periphery of the hole and ejecting a solid slug at the end of the cut, less material is converted into 'chips', requiring much less power than conventional twist drills. The unique geometry of Unibor cutters also helps to achieve faster feed, lower cutting resistance, greater accuracy, longer tool life and a better finish.

The video clip below shows identical machines cutting 25mm holes in the same piece of steel - the broach cutter on the right cuts two holes in the time a standard twist drill cuts one! Doubling your productivity!

Available in a wide range of standard sizes in high speed steel and tungsten-carbide.


cutters significantly reduce your cost per cut!
