In order to get the best diamond core drill performances, a suitable quantity of cooling water needs to be used, according to the diameter of the diamond core drills: REDUCE THE COOLING WATER PRESSURE WHEN THE CORE DRILL DIAMETER INCREASES.

For exemple a 6 mm diamond core drill need for cooling 4 liters per minute.


These drills can be used on all the single ou double spindle flat glass drilling machines (Intermac, Bavelloni, Glaston, Schiatti, Lattuada, Zafferani, Besana.....) which have a 1/2 inche connexion and require a 75 mm length.
