The average life of the drills depends, ALWAYS, on the type of material, its thickness and the correct cooling and use.

The drilling depth can be about 35 mm.
The NBB VB diamond drill bits can be used to drill the necessary holes for water inlets, drains, light points, etc. Without damaging on the ceramic and stones.
The NBB VB diamond drill bits (diam.6mm to 14mm) has the special cold wax inside to insure appropriate dry drilling and stable performance.
The NBB VB diamond drill bits (diam. 20mm to 75 mm) have a lateral opening that improves the cooling of the bit and facilitates the elimination of solid waste after each drilling.
To make the drill bits last longer life, before making a new perforation, we must ensure that the bit is clean and free of any obstruction.
