Komet has specialised in the design and production of cutting tools since it was founded in 1918 by Robert Breuning, with its first indexable insert KUB drill being developed in 1977. Similarly, Ceratizit has pioneered carbide and coating solutions for the past 95 years. Bringing this depth of knowledge together has resulted in the KUB 100.
Komet’s many years of experience in developing drill bodies using FEM (finite element method) techniques enabled the team to design large chip channels without significant detriment to the drill’s rigidity or tensile strength. In tandem, Ceratizit’s indexable insert contour design and chip-breaker geometry was applied to ensure effective chip control during drilling in various workpiece materials. These geometric features have significantly improved spot-drilling results in particular, making the drilling process efficient when creating diameters from 14 to 27 mm (with a diameter to length ratio of 3xD).
One grade and one indexable insert geometry (interior and exterior) for all common workpiece materials reduces complexity in handling and inventory costs.
The KUB 100 is the first joint development project between Komet and Ceratizit.
