Delivered in individual protection plastic cylinder. To prevent delivery problems. 

Iron brass. Connection half inche. Précision on diameter +/- 5 %. The rotation speed for the spindles and the drilling speed are indicated in the technical information menu  (on the left). Also available with length 95 mm. Other lengths available. Please contact us (same selling price and delivery time than for 95 mm length). 


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. Possible also on Janbac drilling machines which generally require 95 mm length.
