- 4 flute spiral with maximum flute entry enable faster debris removal. - Maximised central core enables more efficient energy. transmission to the drill bit head. - Fully supported carbide head gives longer life and cleaner, more concentric holes for better fixing retention.
- For universal applications from coarse to fine grinding on materials with challenging stock removal properties, e.g. stainless steel (INOX). - Active grinding additives in the coating substantially improve the stock removal rate, prevent clogging and result in cooler grinding. - Abrasive: Aluminium oxide A-COOL.
