Description
diamond drill bits are professionally produced for dry or wet drilling on all types of ceramic, especially porcelain, tile, granice, marble and other hard materials.
With the VB technology, NBB VB Diamond bits can perform both wet and dry drilling on hard porcelain and stones with higher efficiency and longer life.
NBB VB diamond drill bits with M14 thread connection can be used directly on angle grinder.
The recommended RPM for using will be 11,000-14,000RPM.
Average life of drill bits ALWAYS depends on the type of material, its thickness and good cooling and use.
NBB VB diamond drill bits can be used to drill the necessary holes for water inlets, drains, light points, etc.
The total length of NBB VB diamond drill bits is approx. 65mm (for dia.18-150mm) with diamond width of approx. 10mm.
The drilling depth can be approx. 40mm.
The total length of NBB VB diamond bits is approx. 62mm (for dia.5-16mm) with diamond width of approx. 10mm.
The drilling depth can be approx. 35mm.
NBB VB diamond drill bits(dia.5-16mm) has the special cold wax inside to ensure proper dry drilling and stable performance.
NBB VB diamond drill bits(dia.18-150mm) have an opening lateral which improves the cooling of the bit and facilitates the elimination of solid waste after each drilling.
To extend the life of the bits, please follow the correct instructions for using the method.
1. Please do not use the hammer mode of the machine.
2.Before re-drilling, we must make sure that the drill bit is properly installed on the machine, firmly and without any vibration.
3.The drill bit should be clean and free from any obstructions.
4.When you are drilling, only light pressure is needed (in the horizontal direction. The pressure of the weight of the machine will be sufficient in the vertical direction.)
All the data is measured manually, so there will be a certain deviation. Please understand.
