In a nutshell
The right choise for
With the Spit 622200 sharpening stone for diamond core bits, you quickly restore the optimal cutting speed of glazed or dull diamond segments. Intensive drilling in hard materials can polish the segment matrix, reducing drilling progress and causing excessive friction. By simply drilling dry a few centimetres into this dressing stone, you wear away the bonded matrix and expose fresh diamond grit. This straightforward site maintenance re-sharpens both wet and dry diamond core drills instantly, preventing overheating and premature wear while extending the working life of your drilling equipment.
